3cx ignores register requests.

[awinner]

Ive just set up 3cx v10 on my machine, it registers outbound sip providers ok but ignores the requests from my ip phones to register, the 2 phones im using are a siemens 470ip and a cisco 7940. Im using wireshark and i can see the register requests come to my machine but 3cx server just ignores the requests.

In my frustration i set up Axon PBX with identical extension details and I have no problems with the phones registering with Axon pbx on the same machine. (yes, i make sure both Axon and 3CX do run at the same time); Both phone also register with external providers fine.

Any ideas?

Look at, or port, the 3CX server logs, showing the attempted request ,if it's showing up. There should be a clue, in there, as to why it is failing.

Doesnt show in the logs, interestingly ive discovered accidentally, that rebooting my router allows 3cx to register the phones just after boot once. When the register expires the pbx ignores all attempts to re-register.Nothing at all shows in the logs except the one succesful attempt to register and the expiry.

If it is only showing once in the logs, and you know for certain that the sets are trying to re-register, then I would suspect some sort of firewall issue on the PC.

Thanks a heap for that, you are absolutely correct. It was windows firewall, even though it appeared that it was allowing traffic to the program it wasnt. I turned of windows firewall and both phones register no problem.
