[asterisk-users] Fax Blast over IP?

[Jonathan Creasy]

I have some customers that come in via SIP on a T1 and then we drop 
their calls off on a PRI. They can fax with about a 98% success rate 
using an ATA->SIP over a T1->Ethernet-> Asterisk -> PRI->PSTN. As long 
as the fax machine can negotiate 9600 baud it will work. We have a 
customer doing this and there is one place they can not fax and it's 
because the fax machine at the other end will not negotiate a speed 
lower than 14400 baud.
