[Freeswitch-users] T.38_gateway & switch_core_media_bug : increase "timeout"

[Weera Suriya]

Thanks Anthony,
It works!

I did 2 basic tests with FS T.38 gateway and CallWeaver T.38 gateway.

Test 1 (PSTN to T.38 ATA)
--------------------------------------
60 voice (concurrent) calls & 30 FAX (concurrent) calls
success rate;
for FreeSwitch : 97.3% with 10,000 faxes(single A4 text document)
for CallWeaver : 83.2% with 10,000 faxes(single A4 text document)


Test 2 (PSTN to T.38 ATA)
--------------------------------------
30 FAX (concurrent) calls
success rate;
for FreeSwitch : 97.8% with 10,000 faxes(single A4 text document)
for CallWeaver : 99.4% with 10,000 faxes(single A4 text document)

FS is best for my situation!

Here is my new dial plan.(for archival purpose)

dialplan for G711(from PSTN/SS7 via SIP) to T.38(to SIP ATAs)
------>8--------
    <extension name="g711_to_t.38">
      <condition field="destination_number" expression="^1(0\d{8})$">
<action application="set" data="t38_gateway_detect_timeout=60"/>
<action application="pre_answer"/>
<action application="set" data="ringback=%(1000, 4000, 400.0, 400.0)"/>
<action application="t38_gateway" data="peer"/>
<action application="bridge" data="sofia/external/$1 at 192.168.11.53"/>
<action application="hangup"/>
      </condition>
    </extension>
