Home / Support / REGISTER TRUNKS – OUTBOUND TRUNKING

Outbound trunking is a feature that allows you to present other direct dial-in (DDI) numbers as Caller ID on your registered trunk relieving phone administrators the onerous task of individually registering large blocks of numbers to preserve CLI.
Using Registration (i.e. not Peering) – system administrators can only present the registered number as the Caller ID which quickly becomes unmanageable for phone administrators managing large number blocks.
