IP 7000 does not pass DTMF


IP 7000 does not pass DTMF

I have an IP 7000 UCS and Boot ROM

part # 3111-40000-001 Rev J.

I have all files sip.config


reg-basic.cfg and reg-advanced.cfg loaded in the provisioning server . I also get an IP address from a DHCP server.

All IC and OUT calls work ok. The problem is when I connect to the voice mail , RMX video bridge or when I call to an IVR I can't send DTMF .

Would appreciate any ideas .

What I 'm missing in the sip.config or some other files in the provisioning server.
