Service resource items (49) for use in call setup in a telephone system are held on servers (58) that are connected to a computer network which is logically distinct from the telephone system infrastructure; this computer network may, for example, make use of the Internet. Each service item (49) is locatable on the network at a corresponding URI and is associated with a particular telephone number. A mapping is provided between telephone numbers and the URIs of associated service resource items. When it is desired to access a service resource item (49) associated with a particular telephone number, this mapping is used to retrieve the corresponding URI (step 55) which is then used to access the desired service resource item (56, 57, 59).

The invention claimed is: 1. A method of accessing, or facilitating access to, a target entity identified by a number string, in which the domain name system (DNS) of the Internet stores records each associated with a corresponding domain name and holding a uniform resource identifier (URI) of an entity associated with the domain name, each said domain name being related to a respective number string from which it can be derived by a process including parsing at least a portion of the number string into at least a part of said domain name, said method comprising: (a) applying, by a computing system, said process to the said number string identifying the target entity to form the related domain name; (b) supplying the domain name formed in (a) to the DNS to retrieve the URI held in the corresponding said record, the URI being that of the target entity; and (c) using the URI retrieved in (b) to access, or facilitate access to, said target entity. 2. The method according to claim 1, wherein the said number string identifying the target entity is of telephone-number form. 3. The method according to claim 1, wherein the URI of the target entity comprises an access scheme and host address. 4. The method according to claim 1, wherein the target entity is an information entity which is accessed in (d) to retrieve information. 5. The method according to claim 1, wherein the target entity is a logging entity which is accessed in (c) to log information. 6. The method according to claim 1, wherein in (c) the URI of the target entity is resolved into a network address of the target entity. 7. A method of accessing a target entity identified by a number string, said method comprising: (a) storing in a database records each associated with a corresponding domain name and holding a uniform resource identifier (URI) of an entity associated with the domain name, each said domain name being related to a respective number string from which it can be derived by a process including parsing at least a portion of the number string into at least a part of said domain name; (b) applying, by a computing system, said process to the said number string identifying the target entity to form the related domain name; (c) supplying the domain name formed in (b) to the database to retrieve the URI held in the corresponding said record, the URI being that of the target entity; and (d) using the URI retrieved in (c) to access, or facilitate access to, said target entity. 8. The method according to claim 7, wherein the said number string identifying the target entity is of telephone-number form. 9. The method according to claim 7, wherein the URI of the target entity comprises an access scheme and host address. 10. The method according to claim 7, wherein the target entity is an information entity which is accessed in (d) to retrieve information. 11. The method according to claim 7, wherein the target entity is a logging entity which is accessed in (d) to log information. 12. The method according to claim 7, wherein in (d) the URI of the target entity is resolved into a network address of the target entity. 13. A method of accessing, or facilitating access to, a target entity identified by a number string, said method comprising: (a) forming, by a computing system, from said number string identifying the target entity, a domain name by a process including parsing at least a portion of the number string into at least a part of said domain name; (b) supplying the domain name formed in (a) to the domain name system of the Internet and receiving back from the domain name system a resource record including a uniform resource identifier (URI) of the target entity; and (c) using the URI received back in (b) to access, or facilitate access to, said target entity. 14. The method according to claim 13, wherein the said number string identifying the target entity is of telephone-number form. 15. The method according to claim 13, wherein the URI of the target entity comprises an access scheme and host address. 16. The method according to claim 13, wherein the target entity is an information entity which is accessed in (c) to retrieve information. 17. The method according to claim 13, wherein the target entity is a logging entity which is accessed in (c) to log information. 18. The method according to claim 13, wherein (c) comprises resolving the URI of the target entity into a network address of the target entity. 19. An apparatus for facilitating access to a target entity identified by a number string, said apparatus comprising: a database comprising at least one server storing records each associated with a corresponding domain name and holding a uniform resource identifier (URI) of an entity associated with the domain name, each said domain name being related to a respective number string from which it can be derived by a process including parsing at least a portion of the number string into at least a part of said domain name; and a computing system configured to: apply said process to the said number string identifying the target entity to form the related domain name, and supply the domain name to the database to retrieve the URI held in the corresponding said record, the URI being that of the target entity. 20.
