Everything is working good with a new CM 6.1 SIP trunk to Mitel. Call routing and CLID is working on both directions. My only question is, if a caller calls in from the PSTN to the mitel receptionist's phone, and the mitel receptionists phone transfers the call to our IP Phone (over the SIP trunk), we see the CLID of the receptionist's Mitel phone, not the ANI of the caller. Is there anything special I need to do on the SIP trunk or IP Phone to display the ANI rather than the transferring person's DN?
Thanks for any help you can give.
