Hi,

I'm getting "mod_spandsp_fax.c:1691 sofia/... Error decoding UDPTL (X bytes)" with FS 1.2.10 with t38_gateway.

Path is Carrier Alaw => FS1-Profile1 => FS1-Profile2 => T38 FS2 rxfax ...

FS 1.2.5.3 works!

Dialplan is

   <extension name="Incomming">

      <condition field="network_addr" expression="^1.2.3.4"/>

      <condition field="destination_number" expression="^(01234.+)$">

         <action application="set" data="num=$1"/>

         <action application="set" data="codec_string=PCMA,PCMU,G729"/>

         <action application="set" data="continue_on_fail=true"/>

         <action application="export" data="t38_passthru=true"/>

         <action application="set" data="fax_enable_t38=true"/>

         <action application="bridge" data="{sip_execute_on_image='t38_gateway self nocng'}sofia/intern/${num}@192.168.1.1:41000"/>

         <action application="hangup" data="USER_BUSY"/>

      </condition>

   </extension>

Anything I can try?!

VG,
