I have a small location using cisco 1760, where is only 3 ip phones attach to our main call manager 6.1. That location has H323 trunk with the CCM 6.1 but the router 1760 has vic2fxo card with 2 lines, The issue is when someone call to that office using the pstn and pickup the phone at the moment they closed the call the routes stay with both line busy and for relase the lines the need to reboot the routers, since is a small office the router has a connection plar configure with the extention of the recepcion extension.
Attach is the the picture of the network also files for
the output of the following debugs from a particular call.
1. debug voice ccapi inout
2. debug vpm signal
3. debug voip vtsp all
4. Sh tech(from the gateway)
5. sh voice port summary
