How many g729 Licenses do you have? From: [email protected] [mailto:[email protected]] On Behalf Of Matteo Campana Sent: Wednesday, June 04, 2014 10:48 AM To: asterisk-users Subject: [asterisk-users] Renegotiate SIP audio codec after call is up
Hi All, Asterisk from 11.X branch is able to renegotiate an audio codec after a SIP call session has been established (INVITE and 200 OK)? I have a problem with a reinvite sent by our SIP provider to change audio codec due to the recognition of a fax tone: after the call is established in g729, after a while I have the reinvite sent by the SIP provider with g711 in the SDP; Asterisk (v 1.4.33.1) says "Oooh, we need to change our audio formats since our peer supports only g729" and sends back 200 OK to the provider; at this point I have one no audio. So it seems that Asterisk responds 200 OK to the reinvite but really can not change the codec. Is that correct? Best regards, Matteo
