Sending faxes over VoIP (for example, from a fax machine connected to an ATA) with Asterisk in the middle is near impossible and certainly not reliable. The problem is Asterisk does not support T.38 (and many ATAs also do not). However, the next version of Asterisk (1.4) will support T.38 for the first time which should improve things significantly. On the other hand, using Asterisk as an end-point connected directly to the PSTN via some hardware (FXO or PRI card) works almost 100% reliably with the more recent versions of SpanDSP. John
