CUBE config for SIP & BRI

[Suchi]

HI ,

I need to configure CUBE with SIP as primary  & BRI as backup. Both connections goes to same ITSP. How do I fail-over to BRI, when the SIP failure & recover back to SIP when the SIP comes up? CUBE also has SRST.

Thanks

In the CUCM, I will create a RG with Top Down Configuration, and inside with two SIP Trunks, one to the CUBE on Top and another to GW BRI on the bottom.

In the CUBE I will put sip-options to sense when the ISTP goes down.

Hi,

in Cube, assign higher preference to SIP PSTN dial peer than BRI dial peer.

In my opinion, CUCM changes are not necessary. As Mohit stated below, you want to have your dial-peers setup with preferences, and you can test that the failover works by shutting down the primary VOIP (SIP) dial-peer. Here's an example of what you would need:

dial-peer voice 1 voip

description ITSP-SIP-TRUNK-PRIMARY

preference 1

destination-pattern 1........

session protocol sipv2

session target xxxxxxxxxxxxxx

voice-class codec X

dtmf-relay rtp-nte

no vad  

!        

dial-peer voice 2 pots

description FAILOVER-BRI

preference 2

destination-pattern 1..........

port 0/0/0

forward-digits 10

I hope that helps.

Thanks,

FG
