[asterisk-users] Different codecs for reading and writing
Hello! I am wondering how to configure Asterisk and devices so I can use different codecs for upstream and downstream packets. Thank you, Elliot

With SIP as the channel technology, at least, the SDP negotiation model demands a uniform codec from both sides. I guess there's nothing to stop two endpoints that both have multi-codec capabilities from using different codecs for send and receive in *principle*, but it would fall outside the standard implementational behaviour of SIP endpoints. -- Alex Balashov Evariste Systems Web : http://www.evaristesys.com/ Tel : (+1) (678) 954-0670 Direct : (+1) (678) 954-0671 Mobile : (+1) (678) 237-1775
