A customer deploys a Skype for Business Server 2015 Enterprise Edition pool and configures Enterprise Voice. The customer deploys Survivable Branch Appliances (SBAs) at each of the remote office locations.
The customer has reported that multiple users in one of the remote offices are not able to dial certain local numbers using Skype for Business. The users receive the error "+1 (425) 555-0100 is unavailable or may not be valid," and the call fails.
The customer has provided the following information form the Local Number normalization rule form the Dial Plan form the remote office that is experiencing the issue:
Pattern to Match: ^1((425 | 206)\d{7})$
Translation Rule: +1$1
You need to ensure that all users at the remote office are able to dial local 10-digit numbers with or without a leading 1.
What should you do?
