Thanks for the help I will see about getting a collect call to come in.

To debug DTMF:

SIP:
debug ccsip messages
debug voip rtp session named

MGCP:
debug mgcp packet

H.323
debug h225 asn1

RFC2833:
debug voip rtp session named

debug vpm signal can be helpful for T1 CAS, FXO, FXS

debug voip dialpeer for SIP/H323 dial peer DTMF.


It may be a signaling issue rather than a pure DTMF issue as mentioned.

One other odd possibility is the way the call is coming in.

I know a while back (we're talking a few years here) calls to certain toll-free IVR based systems were not working in a similar fashion.  The reason for this was that the IVR although it had answered the call was not sending a certain message to the phone company until the caller had gone at least one step into the IVR.  By not sending this one particular Q931 message they were not billed for that first few moments of a call.  The side effect of not having sent that message meant CUCM also thought the call was not terminated and therefore was not changing the phone status from "Ring-out" to "connected".

It is likely the collect call might operate in a similar fashion.  Have someone test an inbound collect call and check the status on their phone when they've answered.  Is it showing "connected" or something else?

We have staff that need to receive collect calls. When we press 1 the collect calls are not being accepted. I have no clue where to look, any ideas?
