[asterisk-users] CLID Presentation & Billing Number | Diversion vs. Remote-Party-ID vs. P-Asserted-Id vs. From vs. P-Charge-info

[Eric Wieling]

It depends on your carrier.    With some carriers, such as Verizon SIP, you do this using P-Asserted-Identity.  With Verizon SIP, if they can’t figure out how to bill the call, it will be rejected.
With Level 3 SIP, you can use From: or PAID but if the number you present to them is not on your account, they will bill the call against the “failsafe” number on your account.

We would like to present a toll free CallerID when making outbound toll calls.  In the past, when our PRIs were directly connected to a Nortel CS1000 we could do this, without issue.  Now that the PRIs are front ended by a mediagateway facing asterisk, we can no longer do this.

Is it possible to set the billing number via a SIP header and set what should be presented as callerid as another header for presentation?

We can't possibly be the only people in the world that has faced this challenge.   Searching the internet has provided limited results.
