[asterisk-users] different codec for different extensions

[Nasir Iqbal]

Hi Mojo,

I dont have control our calling party. and also called extension is only
configured in extensions.conf not sip.conf etc.

So I must select the codec within my dialplan (extensions.com) 

I found one solution by using "SIP_CODEC" variable

like 

[fax]
exten => 605,1,ringing()
exten => 605,n,set(SIP_CODEC=ulaw)
exten => 605,n,RxFAX(/tmp/nasir.tiff|ecm)
exten => 605,n,hangup()

but Thanks for your answer


Thanks 

Nasir Iqbal
