IPT: Clustering Over the WAN
Advantages
•
Component location and administration are centralized.
•
Calls are treated and queued locally, eliminating the need for queuing across a WAN connection.
Best Practices
•
WAN connections to agent sites must be provisioned with bandwidth for voice as well as control and
CTI. See
CTI. See
more information.
•
Local voice gateway might be needed at remote sites for local out-calling and 911. For more

•
Carrier call routing must be able to route calls to the alternate site in the case of a site or gateway
loss. Pre-routing may be used to balance the load, but it will not be able to prevent calls from being
routed to a failed central site. Pre-routing is not recommended.
