  1. PnP Provisioning Issues

    SOLVED Fixed this issue by entering the IP range ino the 'IP Blacklist' section in the dashboard as an 'Allow'. Ironically I looked at this earlier but given the naming dismissed it as a problem. Of course the behaviour of the phones not being seen now makes complete sense. Perhaps 'IP...

  2. PnP Provisioning Issues

    Hi Marios I ran a capture and from what I can see the server sees the request from the phone (192.168.16.67) to subscribe. But I don't understand what the rest means! I filtered using the phone's IP rather than 244.0.1.75 but the first line with that filter shows the PnP attempt, Not sure...

  5. PnP Provisioning Issues

    PBX is 192.168.16.2 and the phone is 192.168.16.67. Same network. Same subnet. They all worked this morning. No change to network environment - just using 15.5 instead of 12.5...

  8. PnP Provisioning Issues

    BTW I added an account to a the 3CX app on my iPhone and that's working perfectly. All roads point to a network issue but network was fine this morning which brings me back to a 3CX setting?

  9. PnP Provisioning Issues

    Thanks for quick reply. The phones have the latest firmware as recommended by 3CX (test phone in question on my desk is Yealink T22P with 7.73.0.60) I don't remember the local or DNS option when I set up? Local if I had to guess?

  10. PnP Provisioning Issues

    Hi New install of 15.5 today. Nuked our old 12.5 and have started again. Everything okay EXCEPT I cannot get the Yealink phones in our office to appear in the phones node. I have the latest firmware and have done factory resets. Windows firewall is turned off (Server 2012 R2). I've tried...
