Outbound Script GET DIGIT String DTMF Relay issue?

I have a script that dials outbound using the "PLACE CALL" step.

Once it connected it runs a get digit step where it asks for digits from the person it called "Enter Code"

The person on the other end is supposed to enter a code, but the digits are not being recognized.

It's almost like a "reverse" DTMF-Relay issue, but POTS dialpeer's don't have DTMF relay options.

Any thoughts?

Re: Outbound Script GET DIGIT String DTMF Relay issue?

these are outbound calls - so they don't hit a VoIP peer.

I've run into the same issue.  Did you ever find the resolution?

Re: Outbound Script GET DIGIT String DTMF Relay issue?

Please make a SIP trunk with MTP enabled. It should help.

Re: Outbound Script GET DIGIT String DTMF Relay issue?

Two things to add on this thread:

  1. The statement "these are outbound calls - so they don't hit a VoIP peer." is not true. There is always an inbound and outbound dial-peer matched on IOS. If you do not have an inbound dial-peer to match, IOS will use dial-peer 0 which is almost always a bad thing. Make sure you have a VoIP dial-peer that will match for inbound calls from UCM to the router.
  2. CCX does not support in-band DMTF such as RFC2833 with SIP. If you do not have OOB DTMF such as KPML (RFC4730) or H.245 alphanumeric, then you need to invoke an MTP for conversion.

Re: Outbound Script GET DIGIT String DTMF Relay issue?

I found my issue.  There was no outbound dial peer on the gateway and the outbound calls were hitting the default dial peer.  Once the outbound dial peer was added, it worked fine.
