asterisk users - Nov 2004 - overriding DTMF and codec from dialplan?

hi

is it possible, from an agi script or directly in extensions.conf, to 
override the DTMF and codec settings?

to answer my own question
SetVar(SIP_CODEC=g726)
allowed me to force g726, but only on outgoing calls.
when dialling in from the iax server, I do the same, setting the codec 
etc, but this does not work. sip show channels only shows the channel 
using alaw

Change this into SetVar(_SIP_CODEC=g726) and it will work.

sipgw1:/usr/src/asterisk # grep -r _SIP_CODEC .
sipgw1:/usr/src/asterisk #

The leading underscore means the variable will be inherited by the 
outgoing channel. Did you try it?
