I think I am having DTMF issues. The users are using Grandstream phones. I just looked at the web interface for one of the phones and the DTMF payload is set to 101 which is default. Under Send DTMF Via RTP is checked. Should in-audio also be selected?
The issue I am having is that users dial a number and randomly receive reorder tone (fast busy) signal. This doesn’t seem to happen with my Xlite users. I could be off on the wrong tangent here. I would like to review a syslog or something to capture what Asterisk is sending out, but I’m not sure how to set that up.
