I am having an issue with an MICS that I can't figure out. The site has a PRI. An extension is placed on forward with an external number entered as the destination (9 - 1 - areacode- number) Calls to that extension's DID are getting forwarded out, but the caller id from the originating caller is not getting passed. The caller id showing up at the receiving telephone is the main phone number for the office that has the MICS. How can I get the caller id to pass through to the forwarded phone.
