Re: [asterisk-users] Asterisk t38passthrough
Finally it's working! I was doing everything well, the problem was that neither the latest branch of Asterisk-t38 worked (http://svn.digium.com/svn/asterisk/team/group/t38passthrough/), neither the patched version of Asterisk 1.2.7. Only the branch of Asterisk-t38 made from source version 1.2.4 works for me. If anyone deployed with success those versions that I didn't make to work, please tell me! Regards, Ricardo.

Re: [asterisk-users] Asterisk t38passthrough
Hi Ricardo, On a 1.2.4 with the T.38 patch, I tried both t38pt_udptl = yes t38pt_rtp = yes t38pt_tcp = yes and t38pt_udptl = yes t38pt_rtp = no t38pt_tcp = no but still got ...chan_sip.c:3716 process_sdp: Unknown SDP media type in offer: image 5144 UDPTL t38 Warnings I tried it on Kapanga Softphone as suggested, and I'll tried it on Grandstream ATA's later. Are there anything I'm missing? Thank you.

Re: [asterisk-users] Asterisk t38passthrough
Assuming that the patch was applied correctly and that each context of sip.conf and also [general] context have all those 3 parameters you mentioned above, try to activate also the accept reinvites option in those contexts of sip.conf. Use ethereal to try to see if communication fails in that second reinvite. Regards, Ricardo.

Re: [asterisk-users] Asterisk t38passthrough
I have enabled in ATA's GUI the T.38 codec as the preferred codec, but of course if it detects that the other side doesn't work with T.38, it tries with the following codec preferences like G.711. On the other side there is PSTN, as I deliver my traffic in IP to a Telco that uses also T.38. The fact is that I think Asterisk-t38 branch installation isn't doing T.38 bypass... If it were, G.711 wouldn't be used... I guess... Any help? Ricardo.

You will need something to translate T.38 to one of the ordinary fax/modem-modulations, when switching to PSTN. Imho, this is not and will never be handled by asterisk's T.38 passthrough support. Anyway, Steve Underwood started to implement some T.38 support for his packages (spandsp/rxfax/txfax). Imho, this is, what you'll need.

Perhaps a stupid suggestion... but did you make sure that the ATA had the T38 selected in the GUI? bp On 8/24/06, Ricardo Carvalho [EMAIL PROTECTED] wrote: Hi,I've installed Asterisk t38passthrough branch and I'm using oneGrandstream ATA to connect Asterisk to a Fax machine.
