Failover between two SIP trunks (CUBE) take long Time Issue

Remon Adel

Dears ,
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 .
Normal Case
Standard Route list Contains ( RG1 then RG2 )
when we try outbound calls , calls success with out any delay .

Failover Case
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 

Please Advice
Thanks

Have you tried these commands on the CUBE.

sip-ua
retry invite 3
timers trying 200

Also, do you have options ping configured on your cubes. This will busy-out
the dialpeers when no service and when cucm sends invite cube will respond
with 503 message immediately without waiting for provider to timeout.

Is the SIP trunk on the secondary CUBE always registered/ACTIVE ? 60 seconds is a huge delay. I doubt it is either CUCM or CUBE.
Can you take a log from the RG2 CUBE ? Also, what happens if you point SIP trunk 2 directly on the RP bypassing SLRG/RG ?

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

Hello Mohamed ,

Thanks for your support ,
The issue has been fixed after adding these configs 

sip-ua

Also Allow keep alive for all dial peers for ISIP

dial-peer voice X voip

voice-class sip options-keepalive
