Hello All, I'm trying to just relay t.38 fax calls along the voice calls between two endpoints with FS in the middle. In the dial-plan I set the proxy media mode to true which works extremely well with my setup considering the codec negotiation headache for my voice calls. My question is do I have to explicitly set any Sofila parameters in the SIP profile or any variables related to T.38 in the Bridge dial string to make the fax go from Caller to Callee through FS? My Freeswitch version is 1.4.19 and mod_spansdp is already loaded Regards, Dave
Hi Dave, You need to set t38_passthru=true in your dialplan to allow the t38 reINVITE to traverse your FS. regards, David ________________________________________ From: freeswitch-users-bounces@lists.freeswitch.org <freeswitch-users-bounces@lists.freeswitch.org> on behalf of Dave Greeko <davegreeko@yahoo.com> Sent: Thursday, 16 July 2015 08:50 To: freeswitch-users@lists.freeswitch.org Subject: [Freeswitch-users] T.38 Fax Hello All, I'm trying to just relay t.38 fax calls along the voice calls between two endpoints with FS in the middle.

Many Thanks David. Should I set this once in Sofia Profile (<param name="t38-passthru" value="true"/>) or per dial-plan extension? lastly, if I can do it in the sip profile without worrying about the dial plan will that have any performance cost in terms of system resources - just a question? P.S: I know for a fact FreeSwitch awesome community may not like these questions because they want us to try it and make it work first than ask.... I'm sorry in advanced -------------------------------------------- On Wed, 7/15/15, David Witham <david.witham@netsip.com.au> wrote: Subject: Re: [Freeswitch-users] T.38 Fax To: "freeswitch-users@lists.freeswitch.org" <freeswitch-users@lists.freeswitch.org> Date: Wednesday, July 15, 2015, 5:50 PM Hi Dave, You need to set t38_passthru=true in your dialplan to allow the t38 reINVITE to traverse your FS. regards, David ________________________________________ From: freeswitch-users-bounces@lists.freeswitch.org <freeswitch-users-bounces@lists.freeswitch.org> on behalf of Dave Greeko <davegreeko@yahoo.com> Sent: Thursday, 16 July 2015 08:50 To: freeswitch-users@lists.freeswitch.org Subject: [Freeswitch-users] T.38 Fax Hello All, I'm trying to just relay t.38 fax calls along the voice calls between two endpoints with FS in the middle.

Hi Dave, It is not a sofia param it is a channel variable so you should set it in the dialplan. Note that it is t38_passthru not t38-passthru. There should be no performance penalty using this variable. regards, David ________________________________________ From: freeswitch-users-bounces@lists.freeswitch.org <freeswitch-users-bounces@lists.freeswitch.org> on behalf of Dave Greeko <davegreeko@yahoo.com> Sent: Thursday, 16 July 2015 11:45 To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] T.38 Fax Many Thanks David.
