Hi
you could also use newest trunk of t38modem + trunk of OPAL. The newest trunk version(s) use SpanDSP as fax engine and it works more reliable than the previous t38 engine (I think it was integrated in OPAL). It also supports fallback to t30 audio fax if you're connected to ISDN network.
Together with HylaFAX+ the success rate is ok (unfortunately not perfect).

The success rate with the latest opal + spandsp code should be about as about good as your system is capable of giving. That is, most failures will either be: - that the call is just a bad call - wrong number, messed up FAX machine usage, etc. - your systems is dropping packets or otherwise screwing up the timing. - T.38 negotiation is screwing up, because T.38 compatibility is still a mess. The last one is such a problem for the whole industry, the SIP Forum has a working group to address it. Steve
