  8. Two phones unable to register

    I got it working , cant remember how but it was working for a period of time. I suspect it stopped working around the same time as the other phones. Nothing network has changed , mobile phone clients and web clients work fine ... just very odd and something I have never seen in the 50+ 3cx...

  9. Two phones unable to register

    No such option, They did actually have more than 3 phones but I cleaned this down yesterday as the person who uses this system had a "play" in the admin panel; so it needed some cleaning up lol 3 phones , 2 of which are SBC's and 1 is a DECT done through STUN although looking at it I think...

    The borrowed phone I provisioned at another location (call it Site B) , this provisioned to the problematic 3cx fine but then after provisioning would not register ... All I see in the logs as they are restricted in SMB is the following: the 213 address is site B , the 82 address is the...

  12. Two phones unable to register

    The handset that I used to test it from another location was from an on prem 3cx system just configured as a standard phone, I wiped it and then provisioned it to the problematic server thus eliminating the network and handsets that have the original problem as I know the network in this other...

  13. Two phones unable to register

    Just to follow on from this, I've tried this from a different phone (another T42U which works fine on an on prem 3cx) at a completely different location / network (one already fully configured for 3cx so I know everything firewall related is good and it will not be blacklisted) , and...

  14. Two phones unable to register

    There is no mention of the blacklist in the logs , the logs show the provisioning file being requested and successfully sent

  15. Two phones unable to register

    I reset the phones then waited over 24 hours to allow the blacklist to naturally expire. As far as I can tell nothing local has changed , it is just a basic internet setup without any complicated firewall etc. The SBC's must be reaching out however as they are getting the config file/data from...

  17. Two phones unable to register

    We have someone using the free version of 3cx , up until a couple of weeks ago they had two router phones registered without a problem. They then went to "no service" I popped to take a look this weekend at them and its an odd one to say the least. I had them factory reset the phones to get...
