I’ve just installed FreePBX distro 5.211.65-1 and ran the upgrade script 5.211.65-2. Asterisk segfaults when it attempts to receive a fax from the PRI and also if I dial 666. My guess is that I’m missing some config option since this is a clean install of the distro. I’ve filled in everything in Settings - Fax Configuration. Thank You in advance for any ideas so I can receive a fax.

Only issue now is res_fax_spandsp.c: WARNING T.30 ECM carrier not found errors while receiving a fax. At least the fax works now and Asterisk doesn’t segfault.
having the same issue. i posted in a few other threads about an earlier distro release. i’m having the same issue with the latest distro release. i will try recompiling spandsp and post my results.
typically, the T.30 ECM errors are fine if the fax is coming through.
Got to the gcc steps in your instructions and received the following errors:

OK I think we have this tracked down. We were asked to upgrade spandsp to solve a few problems another vendor was having and it looks like this is causing the problem. We should have this fixed shortly.
Thanks for the quick fix Tony. If only I would of known about this solution a week ago it would have saved me a complete reload as suggested by your staff.
Sorry we were not seeing the issue here on our systems. It was a specific build of Asterisk that was causing it. Our build was slightly different then what you guys had.
Anyways I rolled a 5.211.65-3 upgrade just now that will resolve this issue for you.
