Hi,

We shall need little bit more information on this.

> What error message are you getting?

> Is the call being routed via a PSTN when you are dialing 7 digits

 

Thanks,

I would start by doing a DNA for the call and look at what results you’d get. Likely it’s a problem with the phones not seeing the 7 digit route information in its CSS.
