VIC3-2FXS/DID which is update version of VIC2-2FXS is not function well although configuration is same as vic2-2fxs, I can able to dial and there is ring but after picking by receiver within seconds line get disconnected I can hardly hear hello**!! from otherside then it cuts. this is happening on both ports.
other details on this issue:
orignal card vic2-2fxs of 2801 was damage so i have to get new but same model is now out of sale & replacement is vic3-2fxs/did.
new card vic3-2fxs/did was not detected so I have to update IOS ipvoicek9mz.124-20T on 2801
copied same configuration (vic2-2fxs which was running smooth but using other version IOS)
dial-peer voice 112 pots destination-pattern 112 port 0/0/0 ! dial-peer voice 113 pots destination-pattern 113 port 0/0/1 !
I notice when i tested sound card localy (hooking telephone sets on both ports) and if i dail number there is ring and sound is good no disconnects no issues atall but when router sends to branch and connects to telephone sets and dail the number from other branch it rings and disconnects after receving hello.
voip configuration (same config is working fine with vic2-2fxs)
