I'm in the process of upgrading from IPBX13-13 to IPBX2020 and did a fresh install and then copy/paste configuration since not a good upgrade path. I'm having a problem getting my Sangoma Vega 50 to connect to the new installation. I copied the trunk configuration information over and then changed the sip ip address in the Vega 50 to the IPBX2020 however the Vega 50 is not connecting. If I do a test call to a number routed to the Vega 50 I'm getting the following message in the IPBX 2020 logs pbx.c: Executing [s@from-sip-external:7] Log("SIP/192.168.*.***-00000003", "WARNING,"Rejecting unknown SIP connection from 192.168.*.***"") in new stack. If I Allow Anonymous Inbound SIP Calls in Asterisk SIP Settings the call does complete but I do not have this option set to Yes in my IPBX13-13 so don't really want to enable in IPBX2020. There must be a setting I'm missing to allow the Vega 50 to connect properly and hoping somebody can point me in the right direction to configure.
