When I receive a call from outside the system and forward the call to another extension, how do I get the extension number that forwarded the call?

There are some suggestions in this string here, please note:
The setting Support Re-Invite: Will allow for a SIP endpoint to send an INVITE in an already established call, while keeping the same Call-ID
The option support replaces enables the support for the REPLACES header, which assists with the transferring of calls (to and from a Shared Parking place or to perform an attended transfer).
