  FYI, 

  We got the one number working.  We had to force the VG224 to do fax and modem passthrough globally and by setting stcapp to enable passthrough on each port. We had to do this even though SCCP (Stcapp) only supports passthrough.

  Commands added to VG224 config,


  voice service voip 
   fax protocol pass-through g711ulaw
   modem passthrough nse codec g711ulaw

  and then this, for each voice port...
   

  stcapp register capability 2/0 modem-passthrough

    try to make sure that ECM feature is disabled. this may cause fax failure

    I have a strange FAX issue, where a FAX machine connected to a VG224 can send/receive FAX to any number but is not able to send one outside number a FAX. It can receive FAX's from them fine, just not send. The FAX machines phone or a phone plugged into the FAX phone line can call the # fine so there is not a CSS issue, etc.

    The FAX machine is plugged into a VG224 with IOS 12.4(11)T , the VG224 is configured as SCCP (stcapp) and we have tried setting the port capabilty to modem passthrough and not with no change.

    The PSTN Gateway is a Cisco 2821 with a PRI, it is MGCP and running IOS 12.4(9)T and has FAX relay disabled.

    We have tried 7 different FAX machines of different models and neither are able to call this particular outside FAX machine when going over IPT. When the FAX machines are plugged into a traditional analog circuit there is not a problem and the FAX works fine.

    Any ideas?
