Everyone remembers the old days before VoIP when PSTN lines ruled the business telecommunication world.  PSTN lines were, let’s just say, a lot less advantageous than what we have today.

One thing we can all remember is putting people on hold. We can still do this today with VoIP, but now there is something more advanced called Call Parking.  This has the same concept of placing a call on hold but gives you more options.

What Is Call Parking And How Does It Work?

In this video, Marc Spehalski will not only talk about the differences between Call parking and putting someone on hold, but he will also demonstrate Call Parking in action using FreePBX!

The latest version of Switchvox, version 6.5.2, is now available! This release includes several bug fixes and Digium Phone Firmware 1.4.6 for the D80.

See the issues have been resolved here:

• Third-party devices (such as a SIP door phone) no longer drop calls when the device cannot accept a SIP UPDATE message. Switchvox now sends INVITE to a device that does not allow UPDATE.
• Queue calls that are assigned to a specific member, while the member is on pause and the caller is receiving a queue announcement, will now correctly ring the member when the member becomes available.
• Correction for the permissions to Manage Admins. Sub-admin accounts requiring Read/Write access to Manage Admins will need to have permission granted again by primary Admin account following the update.
• Modifying a phone-user Ring All action in Call Rules now correctly displays the external numbers that will ring.
• A logging setting that could create excessive logs is turned down. (Larger log files will be rotated away and deleted, so this will not be an ongoing issue.)
• Digium Phone Firmware 1.4.6 for the D80.

VoIP adapters are small, simple devices, but they play an important role for residential VoIP service. We received a lot of inquiries about VoIP adapter. What is it? How does it work? Why is it important? Let’s find out!

What is VoIP Adapter?

A VoIP adapter is a device that converts analog voice signals into digital IP packets for transport over an IP network. A VoIP adapter also converts digital IP packets in analog voice streams.

Standard VoIP adapters connect to analog telephones via an FXS port. The VoIP adapter then connects to your Local Area Network (LAN) with an Ethernet cable via an RJ45 port. Some adapters also feature an FXO port so you can connect to the Publicly Switched Telephone Network (PSTN).

How does a VoIP Adapter work?

Think of VoIP adapters as a bridge between an IP network and an analog station device and/or the PSTN. Depending on where the voice traffic originates from, a VoIP adapter converts voice traffic into the proper form for receipt by the destination network or device:

If the voice traffic originates from an analog telephone or the PSTN, the VoIP adapter will convert the analog voice signal into a digital signal. This signal then is compressed using a codec and broken into a series of packets that will be transferred across the IP network using signaling protocol.

If the voice traffic is from an IP network, the adapter will decompress the digital packets into a digital signal that is converted into an analog signal for receipt by the station device or sent across the PSTN.

Standard Features of a VoIP Adapter

• Compliant with multiple protocols including SIP, H.323 and MGCP
• Support for G.711, G.723.1, G.726, and G.729A voice codecs
• T.38 compliant (for faxing)
• Echo cancellation, Jitter Buffer, VAD and CNG
• Web-based administration/management
• Automatic provisioning via TFTP/HTTP

These are just standard features found in the majority of VoIP adapters. Each VoIP adapter has its own unique differences.
