Multiple Emergency Number Dial Plan

When registering Polycom devices with Skype for Business, you can configure multiple emergency numbers on the Skype for Business server.

When you correctly configure the multiple emergency numbers on the Skype for Business server, users can make calls to the emergency numbers from the Skype for Business client or from a phone, even when the phone is locked.

Polycom phones receive emergency numbers through in-band provisioning and can conflict with the emergency dial string and mask. When a phone receives both multiple emergency numbers and emergency dial string and mask, the client and phone use multiple emergency numbers.
