Outbound caller id

Hi,

Im looking for a system that will act as a SIP and ISDN proxy which will allow me to be able to rewrite the outbound caller id as it passes through. Is this something that Asterisk can do or would i be better placed at looking at other products?

Thanks in advance!

Asterisk is not a proxy; it is a back to back user agent. This means that many protocol fields are re-generated, rather than simply propagated.

However, it can modifyh the caller-ID.

Note that responsible service providers will not accept arbitrary rewriting of caller ID. They will only accept caller IDs that the know that the customer controls.
