strippign the leading 1 on sip trunks?

[RINGINnBLINGIN]

we have a customer that is using a sip provider that includes the leading 1 in the invite. 1) is there a standard or a rule against this? 2) is there any way to strip it? It's causing issues with the contact center solution

thanks!

The standard with SIP is that all numbers should be in E.164 format, although many part from this for whatever reason.

Why is this causing an issue?

int the event you have the 9 also being presented with incoming calls the E.164 format helps with this 1 in the event you are doing mobility it strips the 9 and presents the cell phone with +1-xxx-xxxx instead of showing the 9 resulting in failed callbacks
