RE: Help with DTMF problem

Hello Roman & Sameer, Thanks for the response.

I have eigrp on the routers (Hub and spoke). They use me to get to the PSTN (except when they lose connection I have one or two analog lines configured for SRST on the remote routers). The 6513's are MGCP controlled gateways but there are H323 configurations as well on them in case the CUCM servers go down.

The dial-peers I was referring to is for the H323 configuration. You know "session target ipv4:ip address of one 6513" basically just saying when working as H323 for this destination pattern send it here. The configs are replicated on both and differentiated with "preference" command So the devices at the site am at use them as SRST routers when the need arise. Samples below

On one of the 6513
Dial-peer voi 10 voip
Preference 2
Destination-pattern 5.....
Dtmf-relay h245-alpanumeric
Session target ipv4: 11.11.11.11

On the other 6513
Dial-peer voi 10 voip
Preference 1
Destination-pattern 5.....
Dtmf-relay h245-alpanumeric
Session target ipv4: 11.11.11.12

But this donbt kick in till SRST is in place (correct me if am wrong).

Under the MGCP config I have this command: "mgcp dtmf-relay voip codec all mode out-of-band"

Remote site phones are controlled by the callmanager. I hope I gave better insight.

Thank you.

A little unclear of how the calls get from remote sites to PSTN. You mention "voip dial-peers on the gateways
pointing to each other". Are you saying remote sites phones are not controlled by the CallManager, but by the local
CME (or some PBX + Cisco gateway)? Also, what mode is CMM configured in: H.323, MGCP or SIP?

have bundled T1's or single T1's to me. Some even have 10GB fiber connections to me. All the T1 locations go
into a DS3 I have in one of the 6513 switches. I am marking my signaling as CS 3 and AF31 and giving it 5% on the
links coming to the central site where the clusters are. And yes I have b dtmf-relay h245-alphanumericb configured
under my VOIP dial-peer on the Gateways pointing to each other.
