Description:When moving from Asterisk 1.2.16 to 1.4.1 the DTMF signals on incoming IAX connections (whether local IAX phones or remote IAX incoming calls) are not processed.
Incoming calls from IAX connections cannot access IVR on the server, while incoming SIP connections can.
Local IAX phones cannot access IVR on remote servers, while local SIP phones can.
Moving back to 1.2.16 with same configurations solves the issue.

can you please check out the 1.4 code from svn and try again? I think this was fixed in 1.4 in rev. 58705

If not we will need an iax2 debug plus console output with the debug log option enabled in logger.conf

Checked out SVN-branch-1.4-r58906. Doesn't seem to solve the issue.
I attach debug file generated, and console extracts. I did enable debug option in logger.conf, and issued iax2 set debug on CLI, but did not see so many information to send to you. Hope this helps anyway.
Pls give more detailled instructions if you need more debugging info.

you need to do "set core debug 4" and "set core verbose 4" before "iax set debug"

Debug file was too big ( > 1.9 Mo). I had to zip it.
I included 2 versions of each situation : one with SIP where DTMF is processed correctly, one with IAX where DTMF is failing. Hope this helps.
