We've been using 3CX PABX for quite a while and it has been fabulous. I have 1 x VOIP trunk and 1 x Lynksys SPA adapter. Caller ID has always worked straight out of the box. We used to get the Ring Group name on top line of display and the callers phone number on the second line. (using Polycom 301 phones) The only changes I have made is that I recently changed over my firewall from pfsense to astaro and implemented the SIP proxy - but I can't see how that has anything to do with the problem we now face which is ... all incoming calls (from both the VOIP provider and the PSTN device) now show up as the Ring Group on the top line of the display and "sip:0417XXX192@IPAddress" on the second line where it used to show "0417XXX192" If I return a call from the missed call log on the phone it seems to work fine ??? however as the display is truncated I would prefer it show just the phone number like it used to? Any ideas on what has changed? Could it be a setting that has been updated in the provisioning templates by 3cx and if so which one? I have tried changing the inbound SIP field mapping but it didn't make any difference?
