Hi,
I'm trying to send faxes using Asterisk 1.4 and T38 with sip but Asterisk rejects the t38.
Anybody know if is possible to transmit t38 fax with Asterisk 1.4?
following settings:
--- sip.conf ---
[general]
bindport=5060
bindaddr=0.0.0.0
disallow=all
allow=ulaw
allow=alaw
context=from-outside
t38pt_udptl=yes
[operator]
qualify=no
nat=yes
host=189.160.126.201
dtmfmode=rfc2833
context=from-outside
type=friend
canreinvite=yes
t38pt_udptl=yes
;t38pt_rtp=no
;t38pt_tcp=no
disallow=all
allow=ulaw
allow=alaw
--- channels/chan_sip.c ---
static int global_t38_capability = T38FAX_VERSION_0 | T38FAX_RATE_2400 | T38FAX_RATE_4800 | T38FAX_RATE_7200 | T38FAX_RATE_9600;
