Cisco Unified Communications third-party telephone

Here, we will provide a thorough analysis and explanation of the SIP third-party telephone in Cisco Unified Communication. After the introduction, I believe you can have some knowledge about this aspect. Now let's get to the point and see how to build a third-party phone number for the SIP protocol in this system.

Cisco Unified Presence Server

Cisco Unified Presence Server is a database that collects, summarizes, and transfers user functions and attributes. It supports directory in the network status, click dialing, and personal communication preferences and management. These functions can be achieved by leveraging industry-standard SIP and instant messaging and SIMPLE in-network status scaling features. Cisco Unified Presence Server can be integrated with Cisco's Unified Communication System to provide a standard peer-to-peer environment for all applications or networks that support SIP or SIMPLE.

Cisco Unified Presence Server provides SIP and SIP proxy functions. The SIP in-network status engine provides the basis for user and device status information, such as busy, idle, left, in-network status or availability. It also stores information about users' communication capabilities, such as voice, video, and Web collaboration ). Various communication applications and features developed by Cisco and third parties can use network status information to help users communicate with each other with higher efficiency and better response capabilities, they can also control their own accessible and confidential services.

The core SIP proxy function can efficiently and accurately transmit network statuses and common SIP messages in network and communication applications.

Cisco uniied Presence Server can also interwork with Microsoft Live Communications Server 2005 and Microsoft Office Communicator clients for any Cisco uniied IP phone that is connected to Cisco Unified CallManager. This interoperability includes support for click dialing and telephone control capabilities, and the status of Cisco Unified IP phones in a Microsoft Office Communicator environment.

Many other communication vendors rely on external products to provide network status information. Instead, Cisco leverages the integrated Cisco Unified Presence Server to provide more powerful and diverse network-status features. Cisco supports more important communication applications and services developed by Cisco, the enterprise itself, or a third party.
