I have the following setup:
Nortel Option 11 PBX --- E1 --- Cisco ISR --- WAN --- 2851 (H323) In UK -
-- CallManager --- Mobility Manager --- PSTN --- Deskphone/Mobile
Calls over the WAN to a Mobility Manager user in the UK
are failing. Call will ring on both deskphone and Mobile, if the user
picks up the call on the Mobile they get beeps and call disconnects.
Previously thought this was a codec issue but I configured the current
VoIP dial-peer on the VG in the UK to use only G711 and also set the
Regions between Remote site voice gateway and UK Users to use G711 also. Same
behaviour as before.
Any help or advice would be greatly appreciated
