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.

A unified messaging system is provided that includes two-way synchronization and replication of messages. The unified messaging system includes a workstation, a voice-mail server, and an e-mail server. The workstation may be a personal computer, for example. The workstation includes an agent to monitor messaging activities within the workstation mailbox. Also, the voice-mail server includes a proxy e-mail client (PEC) to operate and retrieve e-mail messages in the absence of the workstation. In accordance with the system and method of the invention, two-way synchronization and replication is provided. The two-way synchronization and replication operates between the workstation and the voice-mail server. Specifically, the replication operates between the e-mail store, e.g., the mailbox, of the workstation and the voice-mail store of the voice-mail server. The replication duplicates messages in each of the mailbox of the workstation and the voice-mail message store of the voice-mail server. Thus, the voice-mail message store contains both the voice-mail and the e-mail. Further, the e-mail message store contains both the e-mail and the voice-mail.
