Caller ID on Attended Transfer #706

Open tw-easy opened 1 year ago

tw-easy commented 1 year ago

Attended transfer is not showing correct caller ID after transfer success.

Example: Extension 122 call 107, extension 107 answer and make an attended transfer to 105, on 105 linphone display 107 as caller but when 107 hangsup and complete the attended transfer the caller number on 105 doesn't change to 122 but remain 107.

On Cisco or Sonm IP phones displays the correct caller ID after attended transfer success.

Caller ID on attended transfer is send on INVITE header SIP: Remote-Party-ID
