Question 16/III - Revision and amendment, if necessary, of charging accounting and associated procedures set forth in the Recommendations on charging and accounting in the international telephone service, their methods of application and the treatment to be applied to them (permanent Question - continuation of Question 17/III studied in 19851988) Reasons for the study Given that WATTC-88 has prepared new Regulations which have an impact on charging and accounting of international telephone service, further study is required. These studies should cover the development, revision and amendment, if necessary, of Recommendations required to provide the appropriate guidance to administrations. Independently of general problems concerning charging and accounting in the international telephone service, special attention should be given to studying charging and accounting principles for international service calls. On that point in particular, and taking into account all the contributions introduced in the previous study period. 1. All the administrations represented in Working Party III/4 accepted the principle that service communications should be excluded from international accounts, although attention was drawn to the fact that such exclusion must not entail complications in international accounting and the expense involved in identifying these service calls precisely or at least adequately. 2. Administrations are invited to consider the practical and financial implications of the principle set out in section 1 above, the final aim being to adopt a single, simple method for dealing with this type of traffic in the accounts and to prepare an appropriate Recommendation. 3. Considering that it may be difficult or impossible for certain administrations to identify this type of traffic accurately in the case of automatic operation, the following points should be considered when preparing contributions on this subject: a) Should the exclusion of service calls from international accounting be subject to bilateral agreement between the two terminal administrations concerned? b) Should the exclusion concern only automatic service calls, i.e. those which in some cases are difficult or impossible to identify accurately? c) In the absence of bilateral agreements, should service calls appear ipso facto in the international accounts and, if so, should this procedure be confined only to automatic service calls? d) If one of the administrations in a given relation can identify automatic service calls but the other administration cannot, what alternative method could be equitably applied to the international accounts?
