UCCX 4x added G.729, however you have to re-install to switch codecs.  It's a permanent choice, any codec change requires re-install with UCCX. I've found music or prompts don't sound good at G729.

The one install I did using G729 with UCCX 4.0(5) I had to re-install using G711 when the music on hold sounded horrible.

In general my opinion is that any "contact center" with customers should sound crystal clear.  If I'm at home and pickup the phone and hear choppy or static or a pause then I know it's an outbound campaign dialer with someone from India trying to sell me protection for my Discover card.

unless something has changed you can't do G729 with IPCCx.  You will need a transcoder for that.  G729 gives you the benefit of lower bandwidth, and quality is only slightly affected (may not be noticable).

Hi all, I'm in a new project, it has 3 clusters with 20 locations each one. It will has 2 servers (PUB and SUB CUCM 7.0), 1 IPCC 7.0, Cisco Unity 7.0 and MeetingPlace Express 20.

Is it possible to have an IPT network only with G729 to avoid mismatch codec problems?

What could be the extra benefits of this IPT to g729?

Thanks for any information.

David
