Call Splitting

Call splitting keeps track of calls where more than two parties are involved. These

can be calls that are transferred, conferenced, or where an attendant becomes

involved. If you have call splitti ng acti v ated and an y of these si tuation s arise, CDR

produces a separate record for each new party on the call.

You can administer call splitting for bot h in coming and outgoing trunks, and both

can have attendant calls recorded separately.

Incoming trunk call splitting

If incoming trunk call splitting is enabled, CDR starts a new record whenever an

incoming trunk call is conferenced or transferred. Whenever a user drops fr om the

call or the call is successfully transferred , CDR produces a record relevant to this

user’s participation. These call records sho w th e amount of time eac h party w as o n

the call, the incoming trunk access code, the dialed number and the condition

code, as well as the other fields specified in the record format.

For incoming trunk calls that are conferenced, CDR creates a new record

whenever a new party comes on the call. The duration field in these records sho ws

how long each party participated on the call. Conference calls produce records

with duration fields that overlap. The duration of a transferred call begins when

the transferring party presses the TRANSFER button for the second time, so there is

no overlap.

If ITCS is enabled and an incoming trunk call is conferenced or transferred to a

local extension that is optioned for Intraswitch CDR, the call produces an

incoming trunk call record. It does not produce an Intraswitch record.

To enable this option, set the Incoming Call Splitting field to y on the CDR

System Parameters screen, and make sure that Record Outgoing Calls Only = n.

ITCS examples

The following scenarios depict calls made with ITCS active. The tables that

follow do not show all fields, only those that may change due to call splitting. Cal l

durations are approximate.

Caller A (TAC 123) makes an incoming trunk call to switch party B (5657890).

They talk for 2 minutes. B then conferences in C (ext. 54321), and D (e xt. 59 876).

The entire group talks for another 8 minutes, at which point B drops off the call.

This produces a record for segment A–B.
