FAQ - Call settings

On this page you can make advanced settings for VoIP connections.
 
It is only available in the Integrator user interface for the user role admin.

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 settings 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 intermediary's connections with the participants are terminated.

Determine 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 worthwhile to test with transfer target address derived from transfer target’s transport address.
