Hopefully someone has run into this issue before. I am working on getting SIP INFO Method for DTMF on Asterisk 1.2.6. My peer config has dtmfmode=info in it, but after it receives and invite from that peer, and respondes with a 200 ok, it does not put INFO in the allow field.
Because of this my originating endpoint does even attempt to send INFO messages to Asterisk because it think that Asterisk doesn’t allow it.
Here is my invite Allow Field.
and the 200 ok from Asterisk allow field:
Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY
As you can see INFO is missing in the 200 ok. This is a bad thing.
Any ideas anyone?
