We have been able to send/recieve faxes with the linksys ATA devices until our recent switch to g729. I have forced asterisk to disallow g729 in the sip.conf for this device and 'sip show peer 3046' does not show g729 as available. Why would we be able to send faxes fine, but not recieve? When sending/recieving, I get the following lines in asterisk console: rtp.c:489 ast_rtp_read: Unknown RTP codec 96 received What can be done to improve fax ability? Are there other methods of doing faxes with *? THanks, Matthew
When somebody sends you a fax and it's attempt to receive, what does sip show channels show? Do you see the codec being used? That unknown codec error is normal. Whenever our fax machines send or receive a fax, it goes nuts on the asterisk cli, but it works none-the-less. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Matthew Boehm Sent: Wednesday, November 10, 2004 12:01 PM To: asterisk-users@lists.digium.com Subject: [Asterisk-Users] Unknown RTP Codec when sending fax We have been able to send/recieve faxes with the linksys ATA devices until our recent switch to g729.
