My problem is that the fax dials out, connects, but can't handle some perceived "line noise" Need to work out or find out what the best settings are for a fax machine connected to a VOIP device per my diagram previously...

What does putting ww at the front do?

What does your extensions.conf look like for this call? If you can insert a ww into your Dial command (ie, change 18005551212 to ww18005551212) this may improve your dialing behavior. _ From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of Mikel Lindsaar Sent: Sunday, December 21, 2008 3:21 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [asterisk-users] Outbound fax issues Hello all. I have the following setup: Fax machine | Sipura SPA-3120 | SIP 100BaseT | Asterisk 1.4 | IAX2 100BaseT | Asterisk 1.6 | ISDN PRI TE210P | Traditional Telco The fax lands on the Internal Asterisk 1.4 box, the sip config for this extension looks like: [35081] type=friend secret= qualify=yes port=5060 nat=no host=dynamic dtmfmode=rfc2833 dial=SIP/35081 context=fax-line canreinvite=no callerid=device <35081> disallow=all allow=ulaw allow=alaw Now, inbound faxing (from the other side of the Telco to me) is working and from what I can tell, never fails to receive. Sending though is a bit touch and go. Sometimes works, sometimes doesn't. It's about a 40% success rate, and does not seem to depend on what number dialed (ie, the problem has been basically isolated to my internal network). The symptoms are long handshake times with the fax trying to get carrier, then failing. Redialing 2-6 times eventually gets the fax through. The extensions.conf simply answers and dials out through the ISDN line. No special config here. I believe from what I have read via our friends at Google and voip forums around the place, that it is probably an echo or jitter problem, but what I have found so far has been a bit vague. Does anyone have any pointers on what I should be looking for to improve the outbound call? Thanks!
