Ringing tone not played to callers during fax detection

General Help
1

I’m using Asterisk 1.4 and FreePBX 2.8. Inbound Zaptel fax detection is working but a ringing tone is not played to callers during the detection. When calling a DID with fax detection enabled, callers hear several seconds of silence after the line is answered before it goes to its normal destination. If I go into extensions_additional.conf and add
exten => 5551234,n,Playtones(ring)
before
exten => 5551234,n,Wait(8)
(assuming the DID in question is 5551234), then it does play a ringing tone to callers during fax detection. Does anyone know if this is a FreePBX or Asterisk issue or how to go about correcting it?

Thanks

I’m just finishing an Asterisk 1.8 w/ FreePBX 2.9 system (based off of AsteriskNOW) and noticed the same thing with DAHDI fax detection.

This patch fixed the problem for me:

} else {

  •       $ext->splice($context, $extension, 'dest-ext', new ext_playtones('ring'));
      $ext->splice($context, $extension, 'dest-ext', new ext_wait($route['detectionwait']));
  }
  }

…Just had to apply this patch against a FreePBX 2.10 / Asterisk 1.8 system :slight_smile:
