Subject: [asterisk-users] Question about codec re-negotiation in asterisk 1.4.X

Hi all,
I have a major issue with a codec renegotiation in an asterisk 1.4.33.1 setup, which leads me to ask a general question about asterisk 1.4.X codec negotiation: asterisk can support a re-negotiation of a codec "on the fly" through a re-Invite? If my SIP provider sends me a re-invite changing codec from g729 to g711, asterisk properly handle the matter?
I see in the trace that asterisk responds 200 OK to the provider, but does not send the re-invite to the UAC, and stops to send rtp to the UAC.
