CUCM Conference Bridge with XCode ressouces low level voice

[guy.richard]

I use CUCM software CFB and Xcode ressources on 2811 with PVDM2-64 DSP's.

Many members join the conferences through an IP Telco, in G729 and they find the voice level too low. For other members on the Head-Quater site (in G711) and members over the WAN (in G729), it seems better.

My question: is it possible to add somewhere some gain, like you can do on voice ports ?

Not really, on this one please open a TA case to investigate further.

If its only trough IP telco, or internal numbers.

Which flavour of G729 ?
