Public IP Address Change

[joebocop]

Hi,

We recently had the public IP address of our PBX change. At the moment, remote extensions can register and place and receive calls without any problem. The config file for 3cx app (windows/android/iOS) that is attached to newly sent "Welcome E-Mails" still contains the old, address, however.

I made the IP address change under "Settings --> Phone Provisioning", and have since rebooted the PBX, but even after doing that, new Welcome E-mails still send with attachment configs having the old public IP address, rather than the new one.

Is there somewhere else in 3CX Phone System for Windows that I need to be making the IP address change in order for it to be fully updated??

Hi,

After changing your public IP in the PBX have you rewrite (update) all the extension config files?

First, thanks for the help.

Second, no, I haven't changed any config files manually. Are you saying that it's a manual process? I had (incorrectly, it seems) assumed that the config files were generated by the 3CX Phone System server.

Where are those config files located?

That is correct. The first time you create an extension a config file for that extension is created.
After changing e.g. IP data, you have to tell the config file there is something changed.
It is possible to change (update) all config files at once and very easy to do this:
Go to Settings > Phone Provisioning, change “Enable Daylight savings time”, click Appy and then revert previous setting, click Apply, then OK.
Now all extension config files are updated.

That's extraordinarily helpful information, thank you.

I manually deleted all the XML files located at

C:\ProgramData\3CX\Data\Http\Interface\provisioning\xxxxxxxxxx\TcxProvFiles

I then re-sent a welcome e-mail (to myself, of course). The config attachment now contains the correct public IP address. Curiously, the <PBXLocalAddr> section now contains the OLD public IP address, rather than the (unchanged) private IP address.

What the?! Any ideas there?

Thanks again for the expertise; very much appreciated.

Hi,

Is it possible to restore the deleted XML files?

Please re-check all IP-address (internal/external) in your PBX, then try again to update the config files as I describe in the previous post.

 

[joebocop]

Yeah, by "deleted" I meant "moved them out of that directory", so I just restored them all, no probs.

Now following your procedure.

Thanks again, I'll update.

Just wanted to "close" this case. My thanks for the suggestion of changing the DST settings, then changing them back. This does, indeed, re-generate the XML files. Perfect!
