Solved: SIP Gateway ISDN

Ian Jones · ‎10-23-2012

Hi

Is it possible to connect a cisco gateway to the PSTN using a E1/T1 interface and connect to the callmanager using SIP

All I can see config for is H.323 and MGCP

Thanks

ian

Ian,

Sure you can have a dial-peer voice voip with seesion protocol sipv2 pointing to the CUCM server.

On the CUCM side you would create a SIP Trunk pointing to the GW IP Address.

thanks - whats the feature comparison like for ISDN and SIP vs ISDN and MGCP?

Ian,

I don't have a side by side comparison for SIP vs MGCP, but from my personal experience I would stick to MGCP.

SIP has pitfalls with MTP in some scenarios, unless there's a company policy favoring SIP over other protocols MGCP works quite well.
