Hi,
I'm planning to put a cisco callmanager together with a Cisco 2921 with CUBE and a SIP trunk used as primary voice trunk.
I'll then have an ISDN acting as back-up for the SIP trunk --> if SIP is not available, calls will be re routed on the ISDN.
Is it enough configuring a dial peer voip and a dial peer pots on the voice gateway (2921) with the same destination-pattern but one configured to use the SIP trunk and the other one to use the PRI access?
Or do i need some configuration on the UCM as well? I have a UCM 8.0
Thanks.

2 dial-peers with same destination pattern alongwith preference statements on both the dial-peers on the 2921 (H323 gateway) should be sufficient.
preference 0 on the SIP dialpeer and preference 1 on the POTS dialpeer. Do let me now how it goes.
Hope that helps

Thanks for that.
A couple of questions:
1 - if the SIP hand off will be a RJ-45, where would it be connected? To a normal switchport of the 2921 would be fine? Or also to a switch that has connectivity to the 2921.
2 - The ISDN will have an E1 hand-off, which card do you suggest to be plugged into the 2921? What s the difference between the HWIC-1CE1T1-PRI and the VWIC3-1MFT-T1/E1 ?
Thanks again.

Hi,

1 - I think a port on the 2921 would be optimal - it would eliminate any switching quality issues and remove a potential point of failure.
2 - You want the VWIC3-1MFT-T1/E1 it is the voice card. The other is for Data over ISDN
