7. A machine readable program code for facilitating efficient development and deployment of additional features in a voice over internet protocol (VoIP) telephony system comprising protocol specific equipment, said machine readable program code, when executed, performing the following method steps, comprising:

a) performing telephony features, employing an arbitrary protocol independent of any specific VoIP protocol used by said protocol specific equipment;

b) providing services in addition the services performed at step a), employing said arbitrary protocol;

c) providing communication protocol conversion between the arbitrary protocol performed at step a) and said VoIP protocol specific telephony equipment responsive to a feature request; and

d) providing communication protocol conversion between the arbitrary protocol at step b) and said VoIP protocol specific telephony equipment employing a single interface layer responsive to a service request

8. A method according to claim 7 wherein said step a) enables features performed by step a) to be revised without inclusion of any commands unique to any specific VoIP protocol used by said protocol specific equipment.

9. A method according to claim 7 wherein said step d) allows for revisions to said protocol conversion based on changes to at least one of said arbitrary protocol and said VoIP protocol.

10. A method according to claim 7 wherein steps a) to d) are programmed into a server located at a customer site.

11. A method according to claim 7 wherein steps a) to d) are programmed into a server located at a developer site.

12. A program product facilitating efficient development and deployment of new features, in addition to existing services provided for a voice over internet protocol (VoIP) telephony system comprising protocol specific equipment, said program product comprising machine-readable program code for causing, when executed, one or more machines to perform the following method steps, comprising:

performing telephony features, said features using an arbitrary developer protocol which is independent of any specific VoIP protocol used by said protocol specific equipment;

performing communication protocol conversion between said developer protocol and a specific VoIP protocol used by the telephony system responsive to feature-related message requests to communicate with the protocol specific equipment supporting VoIP;

performing communication protocol conversion of one of said existing services, which also use the developer's protocol, using a single interface layer between said developer protocol and said specific VoIP protocol to communicate with the protocol specific equipment supporting VoIP.

13. A program product according to claim 12 wherein said method steps further comprise a step of preparing a revision to said feature independently of any specific VoIP protocol.

14. A program product according to claim 12 wherein said method steps further comprise a step of revising said communication protocol conversion based on changes to at least one of said developer protocol and said specific VoIP protocol used by the telephony system.

15. A system for providing voice over internet (VoIP) telephony, said system comprising:

a device for performing an enhanced telephony feature using an arbitrary developer protocol, said developer protocol being independent of any specific VoIP protocol;

a device for providing other services configured to use the arbitrary protocol;

a protocol state machine employing a single layer for converting messages between said developer protocol and a specific VoIP protocol used by protocol specific telephony equipment in the system responsive to a request for said feature;

said protocol state machine for converting messages between said developer protocol and said specific VoIP protocol responsive to a request for one of said services; and

a proxy for communicating messages in said specific VoIP protocol between said protocol state machine and said protocol specific equipment supporting VoIP.

16. A method for integrating a feature into a voice over internet protocol (VoIP) telephony system supporting a given protocol, comprising:

incorporating said feature into the VoIP telephony system employing an arbitrary developer's protocol which is independent of said given protocol;
