I can't think where else to post this but I am trying to figure out how to update the callerid on inbound calls for parked calls and attended transfers.

I am using the Pika Warp with the 2.2.4.4 package and Aastra 55i phones. I used the Aastra scripts elsewhere on this forum to set up the auto configuration of the phones and that works great.
I added the line "sip update callerid: 1" to the aastra.cfg file.
Every search I do for this says it now works but that is all I can find.
Is there anything else I should be changing in any dial plan to get this working?
