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.
I know 1.8.x can do this but. I don't think 1.4.x had the option. Check it
out.
exten => Process,1,Set(SIP_CODEC=ulaw) Thanks
