Hello Everybody
Actually i have a problem on our VOIP Network, we recently give SIP Trunk from out phone provider to Connect to PSTN
our voip network diagram are as below, we use Cisco2911 as voice gateway and CUCM 8.6 as Call Processing Server
PSTN (SIP Trunk) <----> VG <----> Phone (CUCM)
Outgoing calls from Phone (on cucm) are OK but we have issue with Incoming calls from outside; phones are ringing but when phone pickups, other party still ringing and after some sec call disconnected.
for checking the incoming call, i set up Call Manager Express on VG with CIPC registered on it, try to call from outside, call is ok and both party can talk without any problem.
problem is only on phones which registered on CUCM, for solving the problem, i first check the codec between VG and CUCM and also the VG and SIP Provider all of the are G711ulaw
i enclosed the debug ccsip all
i appreciate the if you can help me to solve this issue
Thank you in Advance
