VoIP Users Conference Friday, Nov 7: Wideband Telephony

What’s Happening This Friday?

The VoIP Users Conference weekly call on Friday, November 7, 2008 is all about wideband telephony. That is, using VoIP to deliver call quality vastly superior to the normal public telephone network (PSTN.) Our guest will be David Frankel, CEO of ZipDX, a commercial conferencing service that is specializing in wideband conference calling for businesses.

As usual anyone may join the call which gets underway at 12 noon EST on the Talkshoe conference service. That conference service can be reached by dial-in over the PSTN or by SIP URI. Details on how to connect to Talkshoe by various means can be found here.

For this one call only we will also be using the ZipDX wideband conference bridge. ZipDX and Talkshoe will be connected so that everyone will be on the call. Anyone connected to the ZipDX bridge using a suitable phone will be able to experience the call in G.722-based wideband quality.

Everyone else will experience the normal G.711 based narrowband conference quality that we all know and (despise) love.

Gizmo5 Adds Conference Service

Earlier today I received an email from Gizmo5 offering a new conference bridge. I’ve had an account with these guys since they were known only as “SIPPhone.com.” Like FWD I really don’t use it for much but I do have a phone registered to the account 24/7.

Unlike FWD, Gizmo5 doesn’t seem to be winding down. The availability of a free conference bridge supporting up to 10 people could be very useful.

Junction Networks OnSIP Also Supports HD Voice

OK, so this isn’t exactly news. I’ve been using OnSIP with Polycom IP650 & 550 and a few months already. I hadn’t expected them to support wideband at all but was pleasantly surprised to find that their new conference bridge handles it just fine.

Further, if you’re using suitably capable Polycom or snom phones then calls placed through OnSIP will negotiate to G.722 and voila, much clearer calling. They had a blog post about it a short while ago.

Conference Call Etiquette

Listening to the recording of last Friday's Calliflower conference call with Alec Saunders on Skype & SIP peering I must say that I was embarrassed for the host. There's a tremendous amount of background noise in the call recording from…
