Hello for everybody
I have CUCM 11.5 and two voice gateways connecting to PSTN ISR4431 and 3925E. For the outbound call I use Route List which contains two Route groups. Each Route Group contains SIP trunk to voice gateway. Today I tried to check redundancy and shutdown interface to the PSTN on the first gateway (4431) in Route List. Then I look debug ccsip mess on both gateways. CUCM sent Invite to the first gateway (4431) with shutdowned interface and after that gateway tried to sent more than 10 Invites although the interface is still shutdown and only after 2 minutes gateway sent "SIP/2.0 408 Request Timeout". Then CUCM took second trunk (3925E).
What can I do in this situation? How can I improve it?
Thank you
