[cisco-voip] Telco, New PRI Questions

[Bill Talley]

One thing to note here, the BTN is passed to the IXC, like Marks says, for
billing purposes.  If this is a number the IXC is unfamiliar with on your
account for that circuit, the IXC will likely at some point start blocking
those calls.  For example, if you have two existing CO trunks with number
212-555-1212 and 212-555-1213, the IXC will bill to those numbers to the BTN
on your account.  If your BTN changes on the new circuit and the LEC is no
longer sending 212-555-1212, or 1213 as the BTN, they might eventually
classify the new calls as toll fraud and start blocking the calls.   Long
story short, make sure you long distance carriers knows the new BTN being
used by the LEC.

Additionally, if your customers have become familiar with the outbound
caller id on calls from your office and you're NOT providing the outbound
caller-id over the PRI using external number masks, or route lists, or if
the provider doesn't let you override caller-id, it will likely go out as
this new BTN.  (just noticed this was Mark's point as well)

hope that helps
