INTERNATIONAL TELECOMMUNICATION UNION
ITU-T RECOMMENDATION SUMMARY
Rec. No. : D.110
Title : Charging and accounting for conference calls
Study Group : III - Tariff and Accounting Principles
Version : Revised
Date of adoption : 1992
Notes :
Recommendation D.110 sets out the general principles and conditions
for the charging and accounting of international conference calls. A
conference call is one in which three or more different individual
customer locations are connected through a bridging device, allowing
all call participants to hear and/or address the others.
There are two categories of conference call arrangements. In the first,
the organizing customer arranges to have the conference set up by the
service supplier, and all the participants are called either by the
operator or through some other process at a preset time. The other
category does not require the assistance of an operator to establish
the conference. The conference originator accesses the conference
bridge and dials the conference participants directly, or the
conference participants dial into the conference bridge facility at a
predetermined time.
Recommendation D.110 sets out the charging principles for the
conference bridges and for the calls involved in this conference.
