Hello all,

When I generate an out-going call from *, the DTMF detection is not
working ? ASTERISK --> GW AS5300 --> PSTN

But the DTMF is working correctly when it's an incoming call.
PSTN - -> GW AS5300 - -> ASTERISK

Well, I tried with the 3 dtmfmode of asterisk inband, rfc2833 and info,
no way !!!


Is it  normal that asterisk try to setup the outgoing-call using ULAW ? 
if I disable ulaw the outgoing call doesn't work.
disallow=all
;allow=ulaw 
allow=alaw
debug message:
File chan_sip.c, Line 5590 (sip_request): Asked to get a channel of
unsupported format ULAW while capability is ALAW

Why Asterisk doesn't use the SAME codec with outgoing & incoming calls ?

In my AS5300, dtmf is configured as dtmf-relay rtp-nte
perhaps I should try with h245-signal or h245-alphanumeric ?


ALL ideas will be really appreciated !
Cheers,
Areski
