[asterisk-users] Fax for Asterisk - Fax routing based on TSID

[Karl Fife]

I'm using Fax For Asterisk, and trying to optimize the user experience while 
ROUTING faxes based on the Transmitting Station ID [sic] (NOT the CALLERID).

Specifically I'm trying to eliminate end-user confusion as "that fifty page 
fax" spools to a file, creating a significant delay, leaving the user to 
wonder "why am I not getting my fax--they said it's currently sending".  A 
better user-experience would be to begin TX'ing the fax (at the same or 
slower speed than RX) after a page or two has  been spooled as a buffer.

If I'm using SendFax from the dialplan it appears that I would need to spool 
an entire incoming fax to file (to completion) before I could route said fax 
based on the Transmitting Station ID

However if I were to drive the fax process from manager rather than from the 
dialplan, would the TSID be available for read before RX completion, AND 
(equally important) would sendfax even tolerate sending a fax from an 
still-spooling RX file?  In other words, does the  application require that 
the spool file be complete and closed before it would allow you to begin 
paying it out 'from the top'?
