btw, played with res_fax.conf
if I set maxrate=7200 fax machines try (and fail) 9600 anyway.
Why? If limited ti 7200? looks like bug...
Why do you think everything you don't understand is a bug? What you see
is correct behaviour. Any party in the FAX chain can block V.17, or
V.17+V.29. Only the entity sending a FAX can block individual modes.
That's just how the FAX protocol works.
So I set maxrate=4800 and modems=v27.
Faxes pass....
Looks like problems with V29...
I told you before what where the problem lies. It won't change by
posting more messages like this.

Hello!
I have problems with outbound faxes with asterisk 10.2 t38 gateway.
There is asterisk box, connected to panasonic kx-td500 over PRI link
with TE122.
If we try to send fax with following path:
panasonic 500 extension fax machine panasonic500-> asterisk->
ooh323-> cisco 3845-> fax machine
fax can't pass. always reproducable.
as I see in tcpdump produced dump fax machines tries to connect on
9600 and failed, no attempt to down speed.
If I send fax in path
panasonic 500 extension fax machine -> asterisk (ReceiveFAX) it is
received successefully all the time.
If I send fax from asterisk with SendFax as following:
asterisk(SendFax) -> panasonic500->asterisk-> ooh323-> cisco
3845...-> fax machine
it always passes.
Usually on 7200, sometimes on 4800.
So ooh323 works OK, fax part works OK, t38 works OK, but not with fax
machine (we tested to different).
Inbound faxes in reverse direction, i.e.
fax machine...cisco3845-> ooh323 -> asterisk -> panasonic -> fax machine
always pass on 7200.
More info is here https://issues.asterisk.org/jira/browse/ASTERISK-19436
Bug report was closed because not a bug :-)
Could you help me solve this problem?
Thank you!
Steve
