How To Calculate IP Camera Bandwidth

November 10, 2010 by Nathan Miloszewski

In a vacuum IP cameras are more powerful than their analog/CCTV cousins. However the strength and reliability of a network can bring an IP camera to its knees if the proper amount of bandwidth is not available to handle the information being processed.

A reason why IP cameras are gaining in popularity is because network infrastructures are constantly growing in size and capabilities as are internet speeds.  Just like uploading or downloading images or video to/from the internet, speed plays a crucial role in the quality of that experience.  The same goes for accessing stored or live images from your computer’s network or, accessing them remotely via the internet.

IP Camera Project – Mix of Fixed and Dome IP Cameras

November 5, 2010 by Nathan Miloszewski

Axis Q1755Sometimes a security solution calls for only only type of IP camera such as this high school application that only required Dome IP Cameras.  But in a lot of other applications security needs differ from location to location within a single complex.

When the city of Ningbo in the Zhejiang province of China built a tennis center with the intent to hold international matches and the corresponding daily exercises and daily events, they turned to Axis IP Cameras for their solution.

The Ningbo Tennis Center includes a central court, indoor tennis hall and an outdoor tennis court.  It is a large-scale stadium where, as you can imagine, security is a paramount issue.

3CX Versus Asterisk

November 2, 2010 by Ying-Hui Chen

Note: This blog post was updated on August 7th, 2018 to provide the most comprehensive and accurate information. The post was originally written by GARRETT SMITH.

We all know the capabilities and endless feature set of Asterisk. It’s a powerful, software-based PBX, that’s possibilities are endless. Asterisk is distributed in a number of ways, the first being the open sourced distribution that is command line driven. This distribution, 15.5.0 being the latest stable version can be downloaded from here for free, then compiled with a version of Linux, such as UBUNTU or Centos, and then administered from the command Line CLI interface.

The Flavors of Asterisk

Then we have your open sourced asterisk-based distributions freely available to the public for download. These versions would include trixbox CE, Elastix, FreePBX, PBXinaFlash, and Asterisk Now, which just names a few. The separator between these software applications as compared to the command line asterisk distribution is that while asterisk source code is running in the background, the majority of configuration changes can be made via a Graphical Web GUI interface from both a user and administrators perspective. These software applications also allow for asterisk cmd line access or CLI access in order to make changes if required. Companies such as these have taken the asterisk source code and “rounded” it to their own unique application.

And last but not least, we have our commercial asterisk based PBX’s. Most notability would be Switchvox SMB or SOHO software which is asterisk based, but no access is granted to the asterisk CLI. Rather all configuration changes are done via a web GUI interface. Software from Switchvox is considered a “paid” commercial product, which distinguishes itself from any of the open source based distributions mentioned above.

With all flavors of asterisk, each meets its own unique need and fulfillment in individual VoIP deployments. When it comes to purchasing an IP PBX, you have your choice of asterisk software and also hardware to go along with it. In all regards, whether you choose the free open source cmd line version of asterisk or pay for Switchvox’s award winning SMB software, all solutions present you with a powerhouse feature set and customizability to meet your unique business needs. A short list if asterisk’s feature sets can be found here .

Linux is a Dominant Force

Until most recently, the majority of IP PBXs being deployed were of an asterisk flavor based on a Linux operating system. While companies such as trixbox, Elastix, Switchvox, and many others have made great efforts to take the Linux programming piece out of the picture, the solutions are still Linux based meaning when it came time for your choice of hardware or server to run your asterisk solution, you needed to make sure the motherboard and peripheral components were compatible. See my previous blog posts relating to Open Source Hardware Requirements for more information. If you were not designing your own server platform, of course you could always purchase a Switchvox appliance for your SOHO or SMB solution, or a Rhino or Phoneboch’s appliance preloaded with your desired version of trixbox CE, Elastix, or other open sourced based software. This, however, adds to the cost of your solution.

For the following comparison, I would like to focus on Switchvox SMB software and its comparisons against a new Windows-based PBX, 3CX. The reason for this is that both solutions are “paid” commercial software based applications. Pitting these 2 up against one another would make the most sense from a cost, feature set, and positioning standpoint, so onward to the comparisons.

3CX and Asterisk Comparison

3CX is a Windows-based IP PBX platform that is becoming very popular in the VoIP world. A few benefits of 3CX include:

  • It’s Windows-based. Most of us are used to Windows-based operating systems and applications
  • It is completely software-based and allows you to use existing Windows servers in your existing environment if available.
  • Windows Application Integration support– applications such as Microsoft Exchange, Outlook, Unified Messaging, Microsoft CRM, and SalesForce CRM are all fully supported on 3CX version 9.
  • Feature-rich –  functions and feature sets of 3CX are very comparable to an Asterisk distribution. See here for a complete set of features.
  • Free and Paid commercial versions are available to experiment with and test. Free versions of 3CX software are easily upgradable to any commercial paid version.
  • User Dashboards– the 3CX assistant provides each 3CX user a PC based presence application where they can easily set their calls rules, answer calls; listen to voicemails, and chat.
  • Hotel Billing and PMS integration- On top of their paid software platforms, administrators can add the 3CX Hotel Billing, or the full-blown Hotel PMS integration module to easily integrate Hotel PMS platforms with 3CX. This is a huge hit in the hospitality industry. More information on this support can be found here. For pricing on the software add-ons, see the billing and PMS products on VoIPSupply.com.
  • Non proprietary, SIP Standards-based – Since the 3CX solution is based upon SIP protocol, administrators have the ability to use any SIP-based endpoints such as IP Phones, Gateways, ATA’s ,and DECT Phones . Furthermore 3CX has fully tested a large number of these endpoints and offers full support including auto-provisioning. If you are looking to add some PCI cards to the solution, you will want to go with a Sangoma PCI FXO or T1 Netborder Express card with echo cancellation.
  • Smartphone Apps- 3CX offers and fully supports a softphone application specifically designed for Android and Apple products

Digium Switchvox SMB Advantages

Now onto the Switchvox SMB platform.

  • Third Party Application Integration support– Switchvox SMB integrates very easily with Salesforce CRM, Sugar CRM, Fire Dialer for Firefox users, Notifier Suite to integrate Switchvox to outlook and other Windows applications, and finally an Outlook plug-in to allow click to call from your outlook contacts. More information can be found here. If that’s not enough, Switchvox offers a developer API
  • Feature Support- I always like to refer the SMB platform as Switchvox’s “Big Daddy” PBX, the reason behind it is simple; it is jammed packed with features for both users and administrators. A full list of SMB feature set can be found here.
  • Multiple software versions available- If SMB is too much for you, you can opt for Switchvox SOHO or HOME versions which are more limited in functionality and cheaper in costs as compared to the SMB solution. Also, Digium offers a FREE 60 Day Trial of the full-blown SMB software, so you can “test drive” the actual SMB solution before making your purchase. If you are interested in test driving the SMB solution, contact our VoIP experts at 1-800-398-8647 for details!
  • User Dashboards- Personally, The Switchvox Switchboard, ONLY available with SMB is one of the most intuitive presence applications on the market, and it all comes bundled with your SMB solution. From the Switchboard, users can drag and drop calls to other users, see other users real-time call state, access VM messages, customize to see Google Maps, integration with CRM accounts, Queue status, CDR, Chat, and the list goes on. If you would like to see the switchboard in action, just watch it here.
  • Nonproprietary SIP-based endpoints- While SMB has built-in auto provisioning support via is Provisioning Token system for all Polycom and Snom IP Phones, it is SIP-based, so any SIP endpoint including IP Phone, gateway, ATA, etc will function. If you are looking to add some PCI cards to the solution, you will want to go with any Digium PCI card for your FXO/FXS, or T1 connectivity. Echo cancellation models should also be considered.
  • Smartphone Apps- Digium Switchvox offers a Smartphone application for both apple based products and Blackberry’s. For you Droid users, sit tight, you will get yours soon. The application allows users to create and modify their call rules, access VM, and call into the Switchvox PBX. More information can be found here.

So what do you think? Cost aside, which one would you choose and why?

VoIP Failover with Xorcom Twinstar

October 29, 2010 by Garrett Smith

Introducing Twinstar
what do you know about Failover!!!

If you are new to the VoIP game or are a seasoned veteran, we all know that in business
we need to be able to make and receive phone calls. Most businesses rely on this type of communication to handle the day to day business activities. Also, it is required in most cases of an emergency.  With the introduction of IP PBX’s and VoIP, we all know that there are great ways to reduce costs as they relate to your recurring  traditional phone “bills”, but what happens if your  IP PBX decides it wants to crash and fail. In either case, this is a recipe for disaster. What if you can’t make phone calls? Can you run your business? How much down-time can you afford? These are all questions you must ask yourself and consider when deploying a VoIP solution
because these are all very real scenarios that have happened and could happen to you, that is, if you don’t protect yourself.

IP Camera Types

October 28, 2010 by Nathan Miloszewski

ACTi ACM4201An IP camera, also called a network camera, is a camera with an IP network connection. It can also be described as a camera and computer combined into one unit.  Captured video is transported over an IP network via network switches and is recorded to a PC server with video management software.

That sounds simple enough but when you’re trying to choose the right IP camera you’ll begin to notice how many different types of cameras there are:

That list can be even further segmented but you get the idea.  It can be a dizzying process to wade through the available choices.  But, there’s a reason for all the options and in our ongoing discussion of how to find the right IP camera for your project I’ll be detailing the camera types and how/where they are used.

Oftentimes it’s not just one camera type that’s needed but rather a mix of camera types are utilized to fit the intricate needs of a surveillance system solution.

SOHO DECT Systems

DECT Solutions for your SOHO Environment

So after reading my first two posts on DECT technology and how to design a DECT system, you are now ready to move forward with a solution that fully meets your needs from a hardware perspective. There are a few solutions that are viable to meet your needs with more on the brink. Since DECT phones are becoming more popular by the minute in the VoIP industry, we are seeing manufacturers entering this market and delivering robust cordless solutions that can meet the needs of any SOHO application. Below, we will detail a few of these solutions.

Panasonic DECT Solutions for the SOHO

panasonic_voip

The first solution is actually a new solution and actually a new “player” in the SIP DECT world. Panasonic who is well known for their analog cordless handsets which are very popular in your large retail chain stores such as Best Buy, Target, or Wal Mart have introduced 2 cordless SIP DECT Solutions to the market. The first solution is the KX-TGP550 which is a corded desk IP phone that ships with 1 additional DECT handset which pairs to the base phone. If you are familiar with the Aastra CT solutions, this is very similar EXCEPT, the KX-TGP550 can supply up to 6 additional KX-TPA50 DECT handsets and EACH handset can be allocated as its own individual unique SIP extension unlike the Astra solution that only allows 4 handsets and each handset inherits Line1 configuration of the base phone. Here is a good look at how the KX-TGP550 and KX-TPA50 handsets function.

panasonic_dect_system

The solution allows for 8 individual SIP extensions but SIP extensions may also be shared between each handset and/or base unit. A good look at how this is configured via the web GUI interface is below:
panasonic_dect_screenshot

The KX-TGP550 base phone can also act as BLF/Speed dial application as it contains 6 keys which are each dedicated to a unique handset paired to it. Receptionists can use these buttons to see if the person is on a call or available to take a call and even press that users handset button to speed dial them. They can also press a “ALL” button which essentially calls every handset on the DECT network.  A good look at how this is setup and displayed is below:

panasonic_dect_system_closeup

The next solution offered by Panasonic in the SIP DECT world is the KX-TPG500 which offers a DECT base station that physically connects to your LAN network via cat5 and transmits DECT signal as well handles the SIP registration between the paired DECT KX-TPA50 handsets and the SIP Call server or provider. The KX-TPG500 ships with a single base station and handset. It can support a total of 6 DECT KX-TPA50 handsets and 8 SIP registrations. Here is a good look at how this solution is setup:
panasonic_dect_key_system
Both solutions are viable for SOHO applications and can completely transform your home or small office into an entire cordless mobile phone system. The only downside to these solutions is that there are currently no DECT repeaters available to extend DECT signaling to greater ranges.

snom_logo

The next DECT SOHO solution is manufactured by Snom and has been around for quite some time. The Snom DECT solution is called the Snom M3. The M3 ships with a DECT base station that transmits DECT signal and also handles SIP registration between the 8 additional M3 handsets that can be paired to it. It ships with 1 handset and each handset can be programmed with its own unique SIP extension. The base can handle 3 concurrent calls at any time and unlike most DECT solutions, the M3 DECT solutions offers DECT repeater options that can be spread out within the main base’s DECT frequency to offer a greater range of DECT signal coverage. The base can support up to 6 additional DECT repeaters which can be purchased separately. Below is a good example of the Snom M3 solution and how the DECT repeaters offer greater signal coverage.

snom_m3_dect

Each Snom handset supports a speakerphone option, 2.5mm headset jack, customizable ring/vibrate options, color LCD, out of range notification, low battery notification, and ships with its own desktop charger.
aastra_logo

Aastra also offers a SIP DECT Solution called the MBU-400. The MBU-400 ships with a single MBU-400 DECT base station that broadcasts DECT frequency and handles 8 unique SIP registrations between each paired Aastra DECT 420d handset. The MBU-400 ships with 1 420d handset and can handle up to 8 total 420d handsets which can be purchased separately. The base is unique to other DECT solutions because it can handle 4 concurrent calls, 3 VoIP over the LAN connection, and 1 PSTN via its FXO port. This is also useful in cases where your network may go down. The FXO port is also utilized as a lifeline and calls are automatically routed over to the FXO port if the base loses its SIP registration or network connectivity.

aastra_sip_dect

Each 420d handset offers a speakerphone, 2.5mm headset jack, ring and vibrate options, out of range indications, low battery indications, ships with its own desktop charger, color LCD, distinctive ringing, customizable phonebook, and over the air updates. The downside to the Aastra MBU-400 is it doesn’t offer any DECT repeater option.

siemens_gigaset_logo

And last but not least, we have Siemens Gigaset which offers 2 SOHO SIP DECT solutions, the A580IP and S675IP. Pictured below the A580 IP ships with (1) A58H DECT handset and 1 DECT base station that interfaces with your LAN network. The base can support up to 6 total Siemens Gigaset DECT handsets and Siemens provides a few different models linked and pictured below. All handsets support Wideband voice quality through HDSP technology which is a feature that sets this solution apart from any of the DECT solutions talked about previously.
gigaset_a580

Additional Handsets that are supported on the A580 IP solution and can be mixed and matched include the following:

siemens_gigaset_dect_handsets

The second SOHO DECT solution offered by Siemens Gigaset is the S675 IP. The S675 IP solution ships with 1 S67H DECT handset and like the previous solution can support up to 6 total DECT handsets paired to the S675 IP base unit. The base unit contains a single LAN port to connect to your network as well as 1 FXO port to connect to your local land line. It supports 3 concurrent calls, 2 VOIP and 1 through the FXO port via PSTN. This is also used for failover. Below is a picture of the S675 IP and a listing of its supported HDSP DECT handsets.
siemens_gigaset_s675_ip
Additional Handsets that are supported on the A580 IP solution and can be mixed and matched include the following:

And that about does it for SOHO IP DECT solutions. Stay tuned for my nest post which will describe a few enterprise level DECT solutions.

Digium Announces Asterisk SCF

Nothing like kicking off Astricon with a bang!

In what is becoming a yearly tradition at Astricon, Digium announced it’s latest open source innovation Asterisk SCF.

Asterisk SCF or Asterisk Scalable Communications Framework is an open platform for telephony developers to create voice, video and text  applications that require high levels of availability, scalability, extensibility, fault-tolerance and performance.

Prior to the announcement and development of Asterisk SCF Digium had been consistently dogged by developers and competitors for Asterisk’s lack of “scalability” and “reliability” when put to use for enterprise or carrier applications.

With the release of SCF, Digium hopes to change that.

“The Asterisk community asked for easier ways to use Asterisk in larger and more complex applications,” said Mark Spencer, creator of Asterisk and Digium’s founder and chief technology officer. “They want to make massive scalability and fault tolerance simple, they want rich APIs for developing applications, and they want performance that effectively utilizes modern systems and architectures. Rather than trying to ‘grow’ Asterisk to address these areas, Digium and a committee of Asterisk developers decided that a companion product would be the most effective approach, since it allowed us to consider the widest range of tools, platforms and architectures.”

Asterisk SCF will not be a replacement for the Asterisk software, but a parallel platform for those developers and solution providers who need additional functionality that straight Asterisk does not provide.

For more information about Asterisk SCF or to download a BETA version visit Asterisk.org.
