issue with ISDN inbound call to IP phones using H.323 GW(Codec problem)

Unanswered Question

Hi I have a H.323 gateway configured with to route calls to CCM using G.711 codecs ( codec configuration within dial-peers config ). When PSTN inbound calls are for IP phones configured with locations stating to use G.729 with other ones, the call cannot be completed.

is there anyway to keep using G.711 between the gateway and all others IP devices, and use G.729 between phones belonging to different locations (not using the gateway)?

best regards,

I have this problem too.
