1.6, t.38 and zoiper - t38_udptl or t38pt_udptl ?
...anyone got any success when send a TIFF file form one zoiper
softphone to another ?
I tried using Zoiper 2.18 free edition in windows but I'm seeing 415
Unsupported media replies.
2. Here (http://www.voipinfo.org/wiki/view/Asterisk+T.38), you can read :
"Also, try using:
t38_udptl=yes
t38pt_rtp=no
t38pt_tcp=no
... in the general section of the sip.conf and under the VoIP provider
account as well as the fax account. "
But above, you can read
"[general]
t38pt_udptl = yes "
Has this parameter name changed between 1.4 to 1.6 from t38_udptl to
t38pt_udptl ?

T.38 negotiation error
...system.
When I try to send a fax in T.38 mode I receive this error
ERROR[15035]: res_fax.c:795 set_fax_t38_caps: channel
'SIP/eutelia-sirio-out-00000000' is in an unsupported T.38 negotiation
state, cannot continue.
In my sip.config general section I have added this lines
t38pt_udptl=yes
t38pt_rtp=no
t38pt_tcp=no
If I comment this lines, the fax is sended by G711 but this modality is too
slow and instable.
How can I do to solve this problem?
Thank you

T38 Passthrough testing -- unknown media type error
...ew T38 passthrough code (SVN-oej-t38passthrough-r13347):
- we are using a Sipura SPA-2100 as the T.38 user device
- we are using a Patton SmartNode 2400 as the T.38/PRI gateway
- we are using Asterisk in the middle
We have the following in the [general] section of our sip.conf:
t38pt_udptl = yes
t38pt_rtp = yes
When a fax call comes in from the SmartNode to Asterisk and is then
bridged to the SPA-2100 we see the following messages:

What t38pt_udptl is ? Explain T.38 in 1.4
...MR and JBIG
transcoding ?
2. A softphone like Zoiper is able to receive voice or fax calls. When
setting those values (see bellow) in sip.conf, does it mean :
"t38/udptl will be chosen if a fax signal is detected somewhere in the path.
If none, then alaw would be picked"
t38pt_udptl=yes
t38pt_rtp=no
t38pt_tcp=no
disallow=all
allow=alaw
3. How do you reload updtl.conf ?
Regards

T.38 not working - help needed with log interpretation
Hello,
at first, thanks for helping!
In the meantime, I have done a lot of research and trial and error, and I could solve that specific problem. Obviously, the dialplan application "Answer" was playing a key role here. My original dialplan snippet (which produced that problem) was:
exten => _00., 1, NoOp()
same => n, Set(FAXOPT(gateway)=yes)
same => n,
