It doesn't register anything...

[josersbf]

I have the last version of the software, but it can't register anything (extensions and lines) and I don't have firewall running.

When my first line was added, the software registered it, but with the others it didn't occur and when I restarted my PC, the software didn't register the first line anymore. What is happening?

Server status log

Did you check the server status log?

Please check the latest message, then review:

So you can see at what stage the SIP server is at.

If there are no messages at all - then either you have something like a firewall blocking the communication - OR - you have not entered the SIP proxy correctly in your phones - i.e the registration is being sent to the wrong machine / IP.

There should be error messages in both the server and the phone depending on what the problem is.
