T.38 is good but is a pain. i strongly suggest you to pass it through PCMU (G.711U) codec, sunse you're willing to use E1 boards no transcoding required and less ressources thank you On 21/05/2011 21:17, Chris Cureau wrote:

Hi, everyone!

I am trying to implement a workable fax solution between two FreeSwitch servers. This is what I had in mind so far:

T1 PRI <--> Sangoma A102 <--> FreeSwitch (host) <--> T.38 SIP (internet) <--> FreeSwitch (remote) <--> Sangoma B600D <--> FAX machine

I am assuming here that the T.38 protocol between FreeSwitch servers will ensure that the data transfers between the two sites successfully. Would this actually be a two step process, where one server receives the fax (say, from the PRI) on one call, then sends to the second server, and the second server initiates a second call to the fax machine?

The object here is to successfully pass faxes using SIP. Is there a better way to handle this?

Thanks in advance, Chris

This might be crazy, but are you FAXing others with these two server also, or is it just these two servers FAXing back and forth? Anyway, if it's just these two and you own both side, forget FAX and figure out another way to get docs back and forth :) If you have to FAX others as well, sorry for the noise and good luck. Best, Gabe

Chris, With T38, the simplest seems to be a one-step process: the call received from PRI is routed to the fax machine, with T38 enabled The 2 FS should not have any issue to talk T38. or to avoid T38 at all, as the others proposed, just find a way to transmit the fax as data (rsync, scp, ....)
