VoIP Users Conference Nov 7: HD Conference. Are You Ready?

This Friday’s edition of the weekly VoIP Users Conference call  is all about wideband audio (aka HD Voice) as mentioned in my review of the Polycom IP650 / 550 SIP phones back in August.

The guest for this call is David Frankel, CEO of ZipDX a commercial service that specializes in wideband conferencing. We expect an interesting call touching on many aspects of VoIP going beyond the traditional phone service, conference bridges, technical standards, device compatibility, etc.

The conference call will be held as usual on the Talkshoe service for people calling in from normal phones. Anyone with G.722 capable phones (Polycom, Snom, Cisco, Avaya, Mitel, Grandstream) or a G.722 capable soft phone (Eyebeam) will be able to connect to the ZipDX conference bridge and participate in glorious wideband audio.

The two conference bridges will be connected. People connected to ZipDX directly will be able to hear the startling difference that HDVoice makes. This is especially true in conference calls where line quality, accents and background noise all cause intelligibility issues. The downloadable recording of the conference will let everyone hear the difference for themselves.

Local Provisioning For IP Phones

A short while ago VUCs Randulo tweeted that he had recently updated the firmware on his Polycom phones. He said that he did this using a local provisioning server setup temporarily just for the task. If you’re using a hosted IP-PBX then you may not have a suitable server running 24/7/365.

If you don’t run a provisioning server all the time then booting the phones can take a lot longer. On boot-up the phones simply fail to contact the provisioning server and eventually boot using their existing internal settings. But this means waiting through a series of time-outs, which is the principle source of delay.
