from CME to AVAYA its working because in dial-peer I set the codec G711ulaw command like this:

Actually CME phones uses G.711 by default, however it is also true that "dial-peer voice" uses G.729 by default so you have to set as g.711 as needed.

Now for incoming VoiP calls you will need a dial-peer voice configured with "incoming called-number" and "direct-inward-dial", do you have one ? You can reuse the same DP used for outgoing if you whish.

Hope this helps, please rate post if it does!

Thanks for reply,

Ok, so if i want to use the same this will be ok:

ext 63.. => Avaya

ext 72.. => CME

dial-peer voice 50 voip

destination-pattern 63..

session target ipv4:

incoming called-number 72..

dtmf-relay h245-alphanumeric

codec g711ulaw

no vad

Yes. Ignore the reference about direct-inward-dial, for a moment I made confusion about a pots DP.
