DTMF resource busy...

[IPOFF]

hope someone can point me the direction of DTMF issue.

IP500v2 using T1 with digital and analog phone only. (No VCM/IP)

calls route to user and call forwarded to analog port using DTMFF settings. The problem is analog port always get missing DTMF.

I found the following resource busy at monitor trace...(the following example is 92807 Call forward to analog port ext202. It should received DTMF 92807 when answer the call.

Anyone know how to verify the CMRTTonegen is faulty or it is normal??

Many thanks
