[asterisk-users] Unable to find a codec translation path from ilbc to ulaw

[Oliver Brandt]

Hi!

As the upstream of my DSL-connection is very slow, I'd like my
sip-phones to use iLBC to connect to my *. My gateway provider only
allows ulaw. Hence, I'd like to use the follwing setup:

SIP-phone <--iLBC--> Asterisk <---ulaw----> PSTN-Gateway

I get the following error:

"Unable to find a codec translation path from ilbc to ulaw"

Setup SIP-phone:
disallow=all
allow=ilbc

Setup PSTN-Gateway:
disallow=all
allow=ulaw

I've googled for overn an houre. But no luck. So I'd really apreciate
any help!

Thanks!
Oliver
