[Freeswitch-users] Problem of FreeSwitch and T.38 Test

[chi zhang]

Hi,guys.

    This is sammy.
    Here i met some problem in T.38 fax test on new module:
mod_spandsp(based on the latest src)
    When simulate one T.38 fax receive process with sipP as below:
        1) 1000 calls to 666666, and call is established.
            666666 is one extension in public.xml
                   <extension name="666666">
                     <condition field="destination_number"
expression="^(666666)$">
                           <action application="answer" />
                           <action application="playback"
data="silence_stream://2000"/>
                           <action application="rxfax"
data="/tmp/999.tiff"/>
                           <action application="hangup"/>
                      </condition>
                   </extension>
        2) 666666 send re-INVITE to 1000 with T.38 SDP.
            Here re-INVITE retrys 5 times, and FS return "   Fax processing
not successful - result (48) Disconnected after permitted retries.  "
      i print some logs for libs/spandsp T.30 handle, found in function
t30::repeat_last_command(), t30_state_t->state is T30_STATE_R(17) , so FS
return " Disconnected after permitted retries ".

      Does anyone know the reason?
      Where is the span_log of  spandsp lib ? i cannt  find it...

regards
sammy
