we have issue of long time of failover between two SIP Trunks of two CUBE on CUCM.
Our scenario as below
CUCM (PUB-SUB) ----SIP TRUNK 1 -----CUBE 1----SIP----Telco (SIP Service UP from telco)
CUCM (PUB-SUB) ----SIP TRUNK 2 -----CUBE 2----SIP----Telco (SIP Service Down )
We set SIP Trunk1 in RG1 , SIP Trunk2 in RG2 .
Standard Route list Contains ( RG1 then RG2 )
when we try outbound calls , calls success with out any delay .
Standard Route list Contains ( RG2 then RG1 )
when we try outbound calls , calls success but with high delay about 60 seconds or more.
we modify these setting under service parameters but without luck
set Retry Count for SIP Invite to be 2
set SIP Trying Timer to be 200
Solved! Go to Solution.
Now , we set RP to point directly to SIP Trunk-2 (Which Cube has no sip service from telco), it takes long time to get fast busy tone about 60 s
Kindly find attached run config and output of below debugs
