[asterisk-users] Different codec for different type of calls

[Ali Pey]

Qasim,

Thank you for your response. I tried it but still doesn't work. This is
what I have:

exten => _XXX.,1,NoOP(Set G711 codec)
exten => _XXX.,n,Set(SIP_CODEC=ulaw)
exten => _XXX.,n,Set(SIP_CODEC_OUTBOUND=ulaw)
exten => _XXX.,n,Dial(DAHDI/g1/$EXTEN)

Then I get this error:

WARNING[12156]: channel.c:5796 ast_request: No translator path exists for
channel type DAHDI (native (ulaw|alaw|slin)) to (h264|silk8)
WARNING[12156]: app_dial.c:2277 dial_exec_full: Unable to create channel of
type 'DAHDI' (cause 58 - Bearer capability not available)

I tried both g711 and ulaw with no luck. I read the SIP_CODEC value and it
is set properly.

Any suggestions/ideas?

Thanks,
Ali Pey
