[cisco-voip] Unity xfer Getting 603 from carrier

[fred at browardcommunications.com]

Hello, thanks again for the help, a combination of Diversion and PAI is finally what let the call go through with ATT, so that is working now.
Issue now is, there is a very long delay between the time the caller selects the option, and the call actually gets routed, any thoughts on what would cause this delay?
Thank you.

>>> If your assessment is correct about the calling number, the carrier will see the original or outside caller's phone number in the From field and reject your call.  I see this being solved most of the time with a SIP Profile on the outgoing dial-peer, which adds either a Diversion header or a P-Asserted-Identity header.
