Ring groups with virtual extensions

Q. I have set up two virtual extensions, which call mobile phones.

I have also set up a ring group, and pointed a public number to that ring group. The group has both mobile phones (on virtual extensions) in the group.

What I expect to happen is, when I call the public number, both mobile phones ring until one is picked up.

What actually happens is one of the mobile phones rings.

How do I get this to work?

A. Your concurrent calls limit is probably set too low - please email support@nimvelo.com stating your account username and someone will be able to take a look for you.
