ARCEP launches a public consultation on its draft decision which recommends transmitting caller location data at interconnection for calls made on non-geographic lines

Paris, 13 June 2005

With the generalisation of new electronic communications services, in particular voice over IP (VoIP), some operators are now allowing their customers to make and receive telephone calls on lines identified by non-geographic numbers.


When calls are made on this type of line, the location data (i.e. the telephone number) which is traditionally transmitted to interconnection interfaces is not sufficient to locate the caller.


Caller location information is needed by certain interconnection services invoicing applications, and lets interconnected operators route certain calls to the appropriate call centres (in particular for emergency calls).


At the request of some operators, Autorité de régulation des Communications Electroniques et des Postes (ARCEP, formerly ART) plans to recommend the way in which the fields of the SPIROU and SSUTR2 protocols are to be completed. These protocols are used by interconnection interfaces and are suitable for transmitting this type of data.


This consultation, in the form of a draft decision, follows ARCEP’s initial public consultation on the same subject launched on 27 September 2004.
