Josué, My setup is:
txfax ->[Asterisk] -> E1 Pri ->[Cisco 5350]-> t.38 with Sip -> [Terminating Carrier] So the t.38 is all done by the Cisco 5350 and not by asterisk at all. I have done some tests with a Cisco ATA186, but with limited success using g.711 pass through. I can receive faxes using rxfax with a similar setup but a different carrier. Finally, if I change the Cisco -> Terminating Carrier connection to use g.711 the fax quality is much improved, which indicates that either the Cisco's t.38 or the terminating carriers t.38 is broken or incompatible. - Scott On Tuesday 28 March 2006 7:33 am, Josué Conti wrote: > Scott, as you made to install the T38 in asterisk?
