I am using CCM4.1 and have a MGCP backhaul connected 2811 router with 4 BRI interfaces. These BRI's connect through to the TELCO, thie issue I am having is in regards to DTMF(tones) not being sent over the BRI from the IP Phones, the calls work fine, it's just the tones when using somekind of IVR. IP phone to IP phone is fine.
I have experienced the same issue on CCM4.1 and MGCP BRI gateways.I tried various ios and various gateways (2621xm and 3640) but the problem is still there. The gateways are operating as expected when using FXO interfaces and MGCP but with BRI the DTMF tones are distorted. After a "debug MGCP" command i found that DTMF tones are correclty recognizeg by the MGCP gateway and the BRI interface simply fail to reproduce them over the ISDN line. I couldn't find any reference about this issue on cisco site yet, but as i know BRI support on gateways started on CCM4.1, so maybe is a bug or something.
I had thought it was on by default, and was having trouble with an IVR connection coming in a PRI and over to a device off a VG248 port - the debug I was looking at had caused me to assume it was on, I forget why, but then I discovered it was not. Made a huge improvement when I enabled it.
