Keep it default or adapt it to fit your needs

Here are the parameters that you need to adapt to be able to bill all numbers


SIP Field	Variable	Impact	Explanation
P-Preferred Identity : User Part	Leave default value ~~(old value : "LineNumber")~~	Will not send P-Preferred-Identify Header anymore not to always bill your LineNumber all the time	PPI needs only to be used to define the number to be billed So it is only useful when you wish to display a number out of your range with "Special Arrangement" and bill one specific number of your trunk
P-Preferred Identity : Host Part	Leave default value ~~(old value : "GWHostPort")~~

User Information
- Outbound Caller ID : 0041__ ( Enter here the number to display for outgoing call for this extension from the trunk or external if you have "Special Arrangement / CLIP No Screening" )

Create a new incoming DID rule with a number added in the SIP trunks DDI

Add the following rules

General
- Rule Name = VTX_Default_Rule
- Calls to numbers starting with prefix = 0
Make outbound calls on
- Route: "VTX Services SA" + Strip Digits = 0
