I have problem with fax machine Panasonic DX600. It's connected to Grandstream Handy Tone 386 which is connected to Asterisk. Asterisk is connected to my SIP provider. To some numbers I can't send FAX, and I get following error on CLI. WARNING[2237] chan_sip.c: Unknown SDP media type in offer: image 31358 udptl t38 I believe that Panasonic DX600 machine supports T38. And when I have another T38 fax machine on other end they try to send FAX using T38 protocol. And than I believe I get above error and sending FAX fails. Is there any way to solve this? I hear that there is T38 support in Asterisk 1.4, but I can't wait for version 1.4. In manual for Panasonic DX600 I didn't find any instructions how to turn T38 off. Please suggest something. -- Tomislav Par?ina Lama Computers Split Stinice 12, 21000 Split Tel.: +385(21)270248 Mob.: +385(91)1212148 SIP: tomo@sip.lama.hr e-mail: tparcina#lama.hr http://www.lama.hr
Hi Tomislav, It sounds to me that you have t.38 enabled on your Grandstream Handytone 386. You should disable this on the Handytone. I have a handytone 286 which has an option to disable t.38 and use fax passthrough. This should get rid of your t.38 messages on the cli.

Thank you for your mail. Yes I thought the same. Unfortunately I'm not on the location where ATA is, and I have told one guy on that location to check that option. He checked, few times, and he's positive that option pass-through is on (and T.38 is off). -- Tomislav Par?ina Lama Computers Split Stinice 12, 21000 Split Tel.: +385(21)270248 Mob.: +385(91)1212148 SIP: tomo@sip.lama.hr e-mail: tparcina#lama.hr http://www.lama.hr
