First Look: SIPDroid Open Source SIP Client for Android Mobile Phones

April 28, 2009 by Garrett Smith

SIPDroid is a java based, open source SIP client that has recently been developed for use with mobile devices based on Google’s Android platform.

Based upon a Java SIP stack contributed by MJSip, SIPDroid is currently in public beta.

The SIPDroid Users forum can be found here. The SIPDroid Developers forum is located here.

From the SIPDroid.org website:
After completion of the closed alpha stage this project will publish the software for free under the terms of GNU General Public License v3. The first beta version will be for software testing. So please allow for some issues and incompatibilities at the beginning.

Although SIPDroid will likely mature quickly, it is currently only fully supported using virtual PBX service from PBXes.com. PBXes.com offers a free basic account registration for their service.

Once you have created a basic account with PBXes.com you can set up additional SIP providers/registrars within the Trunks section of their web based UI.

PBXes allows you to register several trunks from multiple telephony service providers of your choice. PBXes routes incoming calls over SIP and the PSTN to you. If you are online you can take a call as VoIP, and if you are offline the call will fall back to GSM.

Beyond their free basic service, a paid account additionally allows for handoff of calls between networks. PBXes also supports NAT.


To install Sipdroid you need version 1.5 “Cupcake” of Android. It is already available from HTC for Android Developer Phones. Visit this link for details on updating the OS. An OTA (over the air) update for the other phones has been announced for coming in the beginning of May.

Tragically, most of us here at The VoIP Insider are Apple iPhone users, but we have procured an Android mobile phone from Yannick Tessier, our head of engineering, for testing purposes. We will attempt to get SIPDroid working this week with Asterisk and let you know how we fare.

Win one of three new IAX phones!

April 22, 2009 by Garrett Smith

A few days ago Insider Cory Andrews leaked information about a new VoIP phone that landed at VoIP Supply which supports the IAX2 protocol. For quite some time Asterisk lovers and open source nuts have been clamoring for a quality IAX compatible VoIP phone.

Well, today we’re proud to unveil the new Citel C4110 and announce a contest that could land you one of these bad boys for FREE (before anyone else) and a custom IAX GIAX (Eeks Geeks) T-Shirt!

Before we get to the contest, let’s look at the C4110.

The Citel C4110 is a stylish business class VoIP phone with two line appearances, dual Ethernet ports, Power over Ethernet, SIP and IAX2 protocol support. The C4110 can also be configured via a web gui or auto-provisioned using TFTP.

All of this for only $99 USD! (Plug: We are now accepting pre-orders. Supply is limited.)

And let’s not forget the IAX GIAX (Eeks Geeks) T-Shirt:

With that out of the way, it’s on to the contest.

The theme of this IAX phone contest is, “Why do you use IAX protocol?”

In order to enter the contest, you must do one of two things (or both if you want two chances):

  1. Leave a comment below about why and or how you use IAX protocol in your VoIP deployment(s).
  2. Write an article on your website, post on your blog, tweet on your Twitter or post a note on your Facebook about the differences between IAX and SIP with a link back to this contest.

This contest will run until Monday, April 27th at 5pm EST. At that time, the Insiders will meet and pick three winners (probably from a hat).

So if you’re interested in getting your hands on an FREE Citel 4110 before others can even buy it and your custom IAX GIAX T-Shirt spend 5 minutes of your time leaving a comment below about why and how you use IAX protocol or use your own site to let the world know about the differences between IAX and SIP!

5 Ways to Minimize the "Hassle" of Switching to VoIP

April 20, 2009 by Garrett Smith

Earlier today Doug Mohney wrote a piece at FierceVoIP about the resistance to migration many cable providers are facing from business customers. In the word’s of one cable company exec, “Nobody wakes up and says, ‘Today I’m going to change all the phones in my business.”

While this may be true, switching to VoIP isn’t a hassle.

At least it doesn’t have to be, since here are a number of things that businesses (and those serving them) can do to minimize the hassle of switching to VoIP.

Labs: Setting Up the Polycom VVX 1500 with Switchvox

Earlier this week we unboxed the new Polycom VVX 1500 Video Phone and promised to share some details of our experience in integrating the VVX 1500 with Switchvox SMB 4.0, the IP PBX that we currently run in production at VoIPSupply.com.

Getting the voice side of things up and running was easy, but we quickly ran into a few issues while trying to make video calls. The Polycom VVX 1500 is currently not supported on the Switchvox platform by Digium/Switchvox or Polycom. There are known issues with the VVX 1500 on Switchvox and both Digium/Switchvox and Polycom are working toward being able to fully support the product.

Being impatient types, we rolled up our sleeves to see if we could come up with a workaround. Shame to have the VVX sitting on my desk and not being able to utilize video calling. Big thanks to our head product engineer and VoIPSupply Labs mad-scientist-in-residence Chris Heinrich for coming up with the following solution. (more…)

One Slick Conference Phone

The folks over at Kicker Studio think conference phones suck.

As such, they decided to go about designing a very slick touchscreen conference phone. Now the folks over at Kicker didn’t just fire-up Photoshop – they went to great lengths to flesh out the hardware and user interface design.

What they came up with is something that you might just be able to buy some day.

Kicker’s touchscreen conference phone combines the humanity of in-person meetings with the convenience of efficient technology. Features include:

  • Synchronizes with calendars and contacts for one-tap dialing
  • Quickly see who’s talking on a call and who wants to speak
  • “Hand Raising” to indicate a desire to speak
  • “Poking” to nudge other callers
  • Recording and marking of calls
  • Multi-line dialing
  • Adjusting individual lines for the best overall conference call quality
  • Comes in four different colors (silver, red, orange, and green)

Who said VoIP hardware was boring?

Update on Polycom VVX 1500

April 15, 2009 by Garrett Smith

Earlier today I wrote a brief piece on the Polycom VVX 1500.

After a smooth and easy setup on the voice side of things, we could not get the video component working. The VVX 1500 performs fine as a SIP endpoint for voice, and the HDVoice audio quality is buttery, as advertised. We could not negotiate video streaming between the two VVX 1500’s we had registered as extension off our Switchvox 4.0 plant however. I contacted Switchvox and quickly learned that the Polycom VVX 1500 is not currently supported on Switchvox 4.0, and that the problems with video negotiation are a known issue that they are working on with Polycom. There is currently no ETA on a fix.

I felt like a kid on Xmas morning opening up a super cool toy, only to find that it takes a non standard battery that they don’t sell in stores where you live. That being said, we are going to test point to point video calls and voice/video calls on Trixbox and Elastix later in the week and I’ll let you know how that goes.

I guess for me it’s back to my beloved Cisco SPA525G….hopefully Polycom and Switchvox are able to complete interop on the video side of things soon.
