Having issues on several 3CX (V20) systems running Generic SIP Trunks back to FreeSWITCH. These systems have been running without issue for many years, a recent 3CX update was applied to the systems over the weekend (10/12, 10/13) and now getting this error on all of our v20 3CX systems:
Registration at XXXXXXX-SIP Trunk has failed. Destination (sip:xxx.xxx.xxx.xxx:5060;lr) is not reachable, DNS error resolving FQDN, or service is not available.
I have other systems that have not received the recent update on v18 and v20, and they are functioning without issue.
