1.71.1.5 PBX Integration Issues
From a PBX perspective, call transfer is most often a sub-feature of Multi-Way Calling
(MWC). MWC provides for several variations of conference call capability. Conference
features are usually accessed via a flash hook followed by the dialing of an access code.
The variation in the behavior of conference features needs to be taken into account when
integrating a CT application on a PBX.
The following behavior needs to be considered:
Swapping between held and consultation calls
If the PBX has conference capability enabled, issuing a second gc_SwapHold( )
could cause a three-way call to be created. This call scenario can no longer be
considered a call transfer scenario.
Remote party drop of consultation call
There are a number of possible behaviors in this scenario. These include:
• getting disconnect treatment on party C, or
• automatically having the talk path connected back to party A (the held call)
Initiating a call transfer (using gc_SetupTransfer( )), then releasing the consultation call
prior to issuing gc_MakeCall( )
Various types of “ring-back” treatments can be applied by the PBX. A “ring-back”
treatment occurs when the PBX generates the ring voltage on any of the parties
involved in the transfer (or conference). The duration of the generated ring can be
from 1 ring (approximately 6 seconds) to 6 rings (approximately 36 seconds).
