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
