Can I have two definitions (accounts) for the same ITSP (Engin) configured?
i.e. on a UC560 can I have two SIP trunks configured to Engin and route calls based on originating DN.
Before you ask why
I have multiple ISDN DID ranges for inbound calls.
My Engin SIP trunks are configured to SET the outbound caller-id to a particular number so return calls come back to reception. I need a second user group to caller-id with a different number when going outbound via SIP hence the second trunk.
