I have tried and tried to set up a dummy extension that can call an external number, but with no luck.
What I want/need to do is have an incoming call ring a ring group of local extensions, then, if not answered, ring a cell phone. I have read threads here that “follow-me” does not work with ring groups and external numbers. And I have read that an external number cannot be used in a ring group.
But in this thread https://forums.grandstream.com/t/ucm-6202-ring-group-issue/32849/11
the issue was apparently solved by setting up a dummy extension which uses “follow me.”
Using the “follow me” feature of a dummy extension you can ring multiple “external numbers” simultaneously or in order, just as you expect from a ring group.
My problem is I can’t even successfully setup a dummy extension with “follow me” as the destination.
When I dial the dummy extension from any valid extension I get:
“Please wait while I try to locate the person you are calling”
“The number you dialed is incorrect”.
Why? I have the same setup on real extensions that work correctly and dial out to the cell number. But with the dummy extension it does not. Why not?
Any help would be very much appreciated.
