Call Termination
VoxOffice™ 2.5.5
PBX Server Administration
PBX Call Termination
Call Termination is a complex area and the following five options, ZAP, SIP, IAX, Channels,
and Speed Dials must to some degree be considered together.
The PBX Call Termination section provides the building blocks needed to implement Least
Cost Routing. Chosen call destinations to the PSTN require a trunk to terminate. Trunk
types available in VoxOffice are:
ZAP (ISDN)
SIP
IAX
Please refer to the least cost routing section for more information on how to use the trunks
you have created for making PSTN calls.
