Hi all. I have an issue sending/receiving faxes in next environment: PSTN <-> Cisco (t.38 origination) <-> Mera (t.38 pass-through) 1.1.1.1 <-> 2.2.2.2 Asterisk-1.4.2 (t.38 pass-through) 10.7.8.254 <-> 10.7.8.125 Linksys SPA2100 (t.38 termination). There is a detailed log with sip messages debug in attachment. The summary of the issue is that call is answered, then Asterisk sends to Mera INVITE with m=image in SDP. Mera answers OK also with m=image, and some other parameters. Right after that Asterisk sends BYE to Mera, and i cannot understand the reason for that. Is that a bug?
I can suppose here 2 reasons: 1. missing Contact: header in Mera's OK reply ( line number 601 ) 2. Different T38 capability between asterisk <-> spa2100 Our T38 capability (3856), peer T38 capability (3872), joint capability (3872) (line 482) and mera <-> asterisk Our T38 capability = (3856), peer T38 capability (32), joint T38 capability (32) (line 632) Unfortunately i have no access to Mera, nor Cisco. As we were told, Cisco has next settings for our dialpeer: fax rate 9600 fax-relay ecm disable fax protocol t38 ls-redundancy 5 hs-redundancy 2 fallback none I'm not sure if this is a bug of asterisk and whether i should submit a ticket. But sending/receiving faxes does work if we exclude asterisk from the path and use it like PSTN <-> Cisco (t.38 origination) <-> Mera (t.38 pass-through) 1.1.1.1 <-> DNAT Forwarding <-> 3.3.3.3 Linksys SPA2100 (t.38 termination). Although Fax settings remain the same both at Cisco and SPA2100. Should i provide more information regarding the issue? I would really appreciate any suggestions.
