An Internet protocol (IP) phone is installed in a private branch exchange (PBX) system without a user having to manually correlate the phone's media access control (MAC) address with the phone's extension identifier. In this regard, the PBX is configured to automatically learn the phone's MAC address and correlate such address with an extension identifier entered by the user. Thus, the phone can be installed for use with the PBX system with reduced complexity and burdens for the user.

Systems and methods for installing IP phones

A communications system and associated method distributes media in a communications network. A Session Initiation Protocol (SIP) communication session call is established between a caller and a communications server. A message is transmitted from the communications server to the media server that includes Session Description Protocol (SDP) parameters for media provided by the media server. Media is delivered to the caller in a packet format in accordance with the Real Time Transport Protocol (RTP) to reuse the same socket as the source IP and port numbers and update RTP timestamps and sequence numbers. The media is transferred to the caller with minimal jitter buffer flushes and network resource usage.

Communications system and related method of distributing media

In accordance with a non-limiting example, the system and method places a call from a first call device used by a party A to a second call device such as used by a party B by routing the call from the first call device into a communications server that establishes an internet protocol (IP) call between the communications server and the second call device. A third call device such as used by a party C monitors the second call device. A first SIP invite command is sent from the third call device to the communications server as a pick-up call instruction for the call to the second call device when it has not answered the call from the first call device. A second SIP invite command is sent between the third call device and communications server and the call is transferred from the second call device to the third call device to establish a communications session between first and third call entities.

System and method for call transfer within an internet protocol communications network

In one non-limiting example, the system and method for communicating establishes a Session Initiation Protocol (SIP) communication session call between a caller and a communications server. The call from the caller is queued at the communications server. A first SIP Invite command is sent between a call agent station and the communications server to dequeue the call. A second SIP Invite command is sent between the call agent station and the communications server. The call is transferred to the call agent station to establish a communications session between the caller and the call agent station.
