I'm not sure how to frame this comment... please bear with me. 1) Fax. You can see in the line that starts “m=” that L3 is sending first “0” which is g711u and then “18” which is g729a. When callweaver answers it is sending the reverse order which will cause g729a to be used. This is unexpected because the order specified the sip.conf is definitely g711, g729.
2) DTMF. On that same “m=” line, after the 0 18 there would be DTMF RTP maps, typically, 100 101. Level 3 does not advertise them on an inbound INVITE . But, I would expect callweaver to specify the acceptable RTP map on the answer, no? Anyway, the result is that both sides are defaulting, likely to different types and dtmf is not working.
