Hello, I've inherited a (now) broken asterisk implementation. It seems as if there are currently codec tanscoding issues in this box. Specifically I am receving calls from a SIP proxy in G.729 and attempting to transcode them to ULAW.
My asterisk installation was working up until yesterday. The information I have found on the voip-Asterisk wiki is for a third party open-source implementation of asterisk (which doesn't seem to be what was deployed on this asterisk box at all); however there are glaring warnings all over the place about possible legal implications of using this codec. Moreover the words "GPL Violation" are printed and duplicated many times over in the form of an E-Mail from Mark Spencer attached to the Wiki. The documentation does not; however tell me the correct and 100% legal way to license and implement G.729. In short this server is broken and I don't know what to do because I'm afraid of possibly being in direct violation of the GPL by following the voip-Asterisk wiki's documentation. Can someone kindly point me to an RTFM in the form of Digium-supported licensing options for G.729 and some technical documentation on how to acctually do the implementation? Or perhaps someone could suggest a fix for my current issues: Here's a log snippet from my asterisk console: Feb 8 22:19:19 NOTICE[1125329728]: channel.c:1683 ast_set_read_format: Unable to find a path from ULAW to G729A Feb 8 22:19:19 NOTICE[1125329728]: channel.c:1650 ast_set_write_format: Unable to find a path from G729A to ULAW -- SIP/2101-aaf2 answered SIP/19544342000-375a -- Attempting native bridge of SIP/19544342000-375a and SIP/2101-aaf2 -- Attempting native bridge of SIP/19544342000-375a and SIP/2101-aaf2 Feb 8 22:19:19 NOTICE[1225991488]: channel.c:1683 ast_set_read_format: Unable to find a path from G729A to ULAW Feb 8 22:19:19 NOTICE[1225991488]: channel.c:1650 ast_set_write_format: Unable to find a path from ULAW to G729A Feb 8 22:19:19 WARNING[1225991488]: chan_sip.c:1797 sip_write: Asked to transmit frame type 256, while native formats is 4 (read/write = 4/4) Now both channels in question have allow=ulaw and allow=g729 Any help at all would be appriciated.
