Can you clarify 'send FAX from SPA3102 to Asterisk' ? Are you running Fax for Asterisk software? Where do you expect your call to terminate?
As I understand it, without FFA or some of the patches floating around, Asterisk is not T.38 gateway aware. Without more information, it's hard to pinpoint the issue, but as a first step, I would *DISABLE* the 'FAX Enable T38' parameter on the SPA3102. This will not help the reliability, but you may see the calls go through properly. A packet capture is always helpful as well. tcpdump on the Asterisk box or Wireshark on a box connected to your switch's mirror/span port will do. Tim Nelson Systems/Network Support Rockbochs Inc.
