I've set up a couple mobile extensions on our SV8100 system. When an outside caller calls, the Caller ID is passed to the mobile extension, but when an inside extension calls to the mobile extension only our main number is shown. Is there a way to have the extension number of the internal extension passed to the mobile extension?

Thanks

I think there is no way because the system used trunk line to reach the mobile

Only way to get that to work is to use SIP clients on a smartphone.

Thanks for the input!
