Hello all.. Please forgive me for what I hope will be a simple question! While trying to set up a new VOIP provider, I am prompted for: External number: Authentication ID: Authentication Password: Maximum simultaneous calls: For these, I enter the information provided by Broadvoice. When I click on Next, I get the error "Please enter a valid external number." I am entering the ten digit phone number provided by Broadvoice in the format: aaapppnnnn. I have also tried 1aaapppnnnn and (aaa) ppp-nnnn. All of these generate the same error. What should I be entering? Thanks!
