9.3.1 Call transfer
Participants can transfer a call to another participant as long as the PBX/provider supports this function. The call
is transferred using the handset menu (via the display key) or using the R key. You can expand or change the set-
tings for call transfer.
Call transfer via R key
Activated: Users can connect two external callers with each other by pressing the R key. The connections with
both parties are terminated.
Transfer call by on-hook
Activated: The two participants are connected with one another when the user presses the end call key. The inter-
mediary's connections with the participants are terminated.
Determine transfer target address
 Select how the transfer target address (Refer-To URI) is to be derived:
From transfer target's AOR (Address of Record)
From transfer target's transport address (Contact URI)
Most common PBX platforms show good results by using the AOR as transfer target address.
In case there are problems with transfer especially via transparent proxies, rather than call switching PBX, it might
be worth to test with transfer target address derived from transfer target's transport address.
