Solved 3CX Forward calls from extension to mobile phone

[TannicArturo98]

Hi, I've setup mobile phone on my extension and when is "available", after 20 seconds it should forward the call to my mobile phone, or "do not disturb" the same thing. When it tries to forward the call, i see my mobile number on logfile with error 480 Temporary not available and the 3CX voice says "Forward call failed". I've setup also an outbound rule with "0" prefix and remove 1 digit. I use a trunk with 8 simultaneous calls. Trunks are registered and works fine inbound and outboud. Why doesn't mobile forwarding work?

First test, can you the mobile from deskphone

Check your outbound rules, are you restricting calls from extensions, or groups. The system will use a system account, so you need to open up the rules.

If you need to lock down the outbound rules, check a rule just for the mobile number,

The 3CX Activity Log will show what's happening with the call...at what point it is failing.

I can call mobile phones using my outbound rule accessibile only from extension, then i Have in first priority mobile forwarding rule.

Hi,
can you screen copy your outbound rules?

If you want to test , remove extensions and groups from your rule, do a call test, if like i guess it works then most surely as Saqqara said, this is a problem coming from a non existing specific outbound rule for system extensions.
System extension are not part of default extesions nor groups,add a rule with only lenght set and order it before more restricted rule

You can also add another extension where you typed your mobile number.

If the extension rings, then the forward works. But most likely in the above case the rules do not allow it to proceed when dialing an external number, and the activity log will probably show you a [Flow] message saying target endpoint cannot be built.

 

[AWS2P]

it shouldn't be "if the extension doesn't ring" instead ?

Issue solved, i've setup correctly forward mobile phone after 20 seconds on extension. Before the person interested gave me wrong mobile number and now with correct number works fine. Thanks for your help.
