Dear all,<br><br>I am doing an interop testing with asterisk-1.6.0.5 now, and I have a question about the G.726 codec on asterisk.<br><br>While my IAD supportes G.726-16,24,32 and 40 codecs, when doing a testing about G.726-40, I found that asterisk removed the G.72-40 sdp attrib when transmitting the INVITE with SDP.<br>
<br>I modified sip.conf in order to solve the problem, G.726-32 is ok when allow=g726, but allow=g726-40 brings nothing.<br><br>So I searched internet about the codec supporting in astersk, and found there is no certain words about it.<br>
<br>following are some references:<br><a href="http://www.voip-info.org/wiki/index.php?page_id=127" target="_blank">http://www.voip-info.org/wiki/index.php?page_id=127</a><br>said that "Asterisk currently supports the 32kbps standard only", but didn't find anything about the asterisk version<br>
<br><a href="http://www.voiptutor.net/voip-info/wiki/view/Asterisk+codecs.html" target="_blank">http://www.voiptutor.net/voip-info/wiki/view/Asterisk+codecs.html</a><br>said that "G.726 - 32kbps in Asterisk 1.0.3, 16/24/32/40kbps in CVS HEAD; flawed until Asterisk 1.4 which corrected the implementation and introduced g726aal2 for backwards compatibility with Asterisk 1.2 installations ", from the article I find that 16/24/32/40 maybe already supported in astersik, but how to config it?<br>
<br>My questions:<br>1. G.726 16/24/32/40 supported in asterisk-1.6.0.5?<br>2. If supporeted, how to configurate?<br><br>Thanks!<br><br>Le'an Liu<br>ÀÖ°²<br>
