I have 2 asterisk boxes: asterisk-alpha (running 1.0.3) and dev-asterisk (running latest CVS). I am the only SIP user on dev, everyone else in the office is on alpha. If someone dials my extension, it should go IAX to the dev server and the dev server should ring me. Here is what I see on the dev machine's console: -- Accepting AUTHENTICATED call from 192.168.1.25, requested format = 256, actual format = 256 -- Executing Dial("IAX2/asterisk-alpha@asterisk-alpha/2", "SIP/3044|30") in new stack -- Called 3044 Dec 27 14:14:06 WARNING[9194]: channel.c:2137 ast_channel_make_compatible: No path to translate from SIP/3044-520a(4) to IAX2/asterisk-alpha@asterisk-alpha/2(256) == Spawn extension (all-incomming, 3044, 1) exited non-zero on 'IAX2/asterisk-alpha@asterisk-alpha/2' -- Hungup 'IAX2/asterisk-alpha@asterisk-alpha/2' I have the following in sip.conf: [general] port = 5060 bindaddr = 192.168.1.26 context = all-incomming tos=lowdelay maxexpirey = 3600 defaultexpirey = 120 promiscredir=yes disallow=all allow=ulaw allow=alaw allow=gsm [3044] type=friend host=dynamic nat=yes disallow=all allow=g729 allow=alaw allow=ulaw canreinvite=yes This seems to be a codec issue but my phone is set for g729 and it appears that the IAX call is comming in as g729. It seems that asterisk is b0rking on the fact that I have no G729 licenses installed on the dev box. But that shouldn't make a difference since asterisk is just passing thru g729. Why would I need a license to go from IAX-G729 to SIP-G729? Thanks, Matthew
