PhonerLite With FRITZ!Box
Hello!
If you want to set up your PhonerLite VoIP/SIP client with the FRITZ!Box so you can receive phone calls on your computer as well, of course you should have a look at the official AVM documentation (like the one for the FRITZ!Box 7390).
However, I encountered the following problems:
- outgoing calls would result in a "480 Temporarily Unavailable" error (even the test number **797)
- saving the configuration (tab "Configuration" => "Save" button) repeatedly would cause the status bar to alternate between
- showing a red indicator and the error message "sip:<number>@fritz.box not registered <Connectivity Checks Failed>" every second click
- showing a green indicator and the message "sip:<number>@fritz.box registered" every other click
I changed the following server / connection settings to fix the problem:
- Proxy/Registrar: <FRITZ!Box IP address instead of fritz.box, e.g. 192.168.1.1>
- Domain/Realm: fritz.box
After that, every time I saved the configuration if would show the success indicator and message and telephony just worked in general.
My local network interface uses an external DNS server for hostname resolution and I have added the fritz.box name manually in my hosts file. This might be why this was causing me problems.
I hope this was of any help to you in case you encountered this as well.
Thanks for reading!
