I noticed when calling International numbers it works, when call forward all to local numbers it works. Tried to call forward all to an International number and the after 10 Seconds the call is released. I checked the T310 timers and it is set to 60 seconds. On the international end the phone will ring once but not enough for the call to go through. On my end I get the provider tone that the call in not available.
I am running IOS (C2800NM-ADVIPSERVICESK9-M), Version 12.4(24)T2, I am running Cisco Unified Communications Manager 7.1.2
Also I unchecked outbound redirecting ie and still nothing. On 10 seconds and we Receive disconnect on timer expiry every time.
The provider says that the problem is on my end, but I asked them if they could increase their T310 timer, but they refuse to.
Any Ideas to get around my problem ?
