PIM. See Peripheral Interface Manager.
Post-query label
A routing label that causes the routing client to re-enter its call routing
plan at a specific point.
Post-Routing
The GEOTEL routing concept that allows the ICR to make secondary
routing decisions after a call has been initially processed at a call center.
Post-Routing enables the ICR to process calls when an ACD, VRU, or
PBX generates a route request. The ICR executes scripts to process the
route request and return a destination address. This directs the ACD to
send the call to an agent, skill group, or service in the same call center or
at a different call center. In making a Post-Routing decision, the ICR can
use all the same information and scripts used in Pre-Routing.
Pre-Routing
The GEOTEL routing concept that enables the ICR to execute routing
decisions before a call terminates at a call center. With Pre-Routing, the
Network Interface Controller (NIC) receives the route request from the
IXC and passes the call information along to the ICR. The ICR is then
able to process the IXC route request through a call routing script, which
defines how calls should be routed. In making its Pre-Routing decisions,
the ICR uses real-time data on the status of call centers. This data is
gathered by Peripheral Gateways at different call center sites and passed
back to the ICR.
Prefix
The leading digits of a telephone number. When defining a call type,
you can specify a prefix of any length to match calling line ID values.
You can also define a region that is a collection of prefixes. If a calling
line ID value matches multiple prefixes, the longest matching prefix
prevails.
PRI. See Primary Rate Interface.
Primary Rate Interface (PRI)
One of two levels of ISDN service. In the United States, the PRI
typically provides 23 bearer channels for voice and data and one channel
for signaling information (commonly expressed as 23B+D). In Europe,
PRI typically provides 30 bearer lines (30B+D).
Private Branch Exchange (PBX)
A device located at a customer’s site that switches incoming calls to
extensions within that site. A PBX can be used to implement direct
inward dialing.
