[cisco-voip] IPT Network with G729.

[Jason Aarons (US)]

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
