Systems and methods for a session initiation protocol (SIP) translator

摘要

A communications network element that includes a call processing software module that provides call processing and services and a session initiation protocol (“SIP”) translator that translates SIP messages to instructions recognizable by the call processing software module and translates instructions from the call processing software module to SIP messages is provided. The SIP translator includes a SIP dialog module that receives SIP messages from endpoints and creates SIP dialog objects that represent an SIP endpoint; a SIP task module that coordinates the SIP translator events and exchange of messages; and a translator dialog module that translates SIP messages and call processing software module instructions and creates translator dialog objects. Methods for translating SIP and call processing software module instructions are also provided. Methods for dynamically allocating gateway channels to couple SIP endpoints and legacy telephones are also provided.

1. A communications network element, comprising:
a call processing software module configured to provide telephone call processing and services; and a session initiation protocol (SIP) translator configured to translate a first SIP message to a first instruction recognizable by said call processing software module and to translate a second instruction from said call processing software module to a second SIP message, wherein said SIP translator comprises:
a SIP dialog module configured to establish a SIP dialog object, representing said SIP endpoint, for a telephone call,a translator dialog module configured to translate said second SIP message and said second instruction from said call processing software module and to establish a translator dialog object, representing said SIP endpoint, for said telephone call, anda SIP task module configured to cause said SIP dialog module to establish said SIP dialog object upon receipt of said first SIP message or said second instruction and to dispatch an event relating to said telephone call between said call processing software module and said SIP dialog module,wherein said SIP dialog object and said translator dialog object are configured to remain open for a duration of said telephone call.
