Keep it default or adapt it to fit your needs

Outbound Parameters[edit | edit source]

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")
