10.125The system can have up to 15 call routing tables. There can be a total of 900 patterns
(more if using a CP Server) in all of the call routing tables combined. To program a call routing
table, see the information on
NOTE:
or later you can copy one or more patterns to a target Call Routing Table (see
the target CRT has a list of patterns, the copied patterns are added to the end of the existing
list.
10.126(For the U.S. only) Each individual trunk, not the trunk group, is programmed to col-
lect digits using Caller ID [CLIP], DID, ANI, or DNIS. If the trunk is programmed to collect
digits, but the trunk group does not use call routing tables, the system routes the call based on
the trunk group programming and ignores the collected digits. (However, the collected digits
appear in SMDR and can be used by the Desktop Interface.) If the trunk is not set up to collect
digits and the trunk group uses call routing tables, the system uses the call routing destination
for "no-digit" calls.
Call Routing on a Network
10.127Call routing operates as follows on an Inter-Tel phone system network:

Sample Call Routing Tables
10.128Several sample call routing tables for U.S. and European systems are shown on the fol-
lowing pages. (Actual tables would have more than the sample entries; these are abbreviated
lists to show how the tables work.)

MANUAL VERSION 11.0 – May 2008
NOTE:
When programming a call routing table that rings in to another call routing
table, make sure the two call routing tables do not send calls to each other, creating a
"loop."
Name: Determines how the call is identified at display phones. It can contain up to 12
characters. The name can be a word or number that identifies the call source. If the
name is left blank, the system uses the priority list shown on
what appears on the phone.

When programming Call Routing Table (CRT), if you are running system software v9.0
You cannot route a call from one Call Routing Table to a Call Routing Table on another
node. When a Call Routing Table sends a call to another node, it cannot be routed to
any additional nodes.
Trunks that ring in to call routing tables can only ring in to tables that are located on
their local node. They cannot ring in to a call routing table on another node.
The network attempts to optimize routes so that calls do not route through a node more
than one time (looping). However, the network does not have the ability to dynamically
reroute. That is, if a node trunk group that was previously unavailable becomes avail-
able after the network has already chosen another route, the network does not reroute
using that node trunk group.
The network tries to optimize routes when calls have been transferred or reverse trans-
ferred across several nodes (possibly forming loops).
