    摘要： In an attempt to establish a communication session between a first communication entity and a second communication entity, a first message is received. For example, the first message may be a SIP INVITE message. A determination is made, based on a registration message from the first communication entity and/or the second communication entity, that at least one of the first communication entity or the second communication entity is Internet Protocol (IP) version intolerant. In response to determining that the at least one of the first communication entity or the second communication entity is IP version intolerant, one or more IP addresses are adapted in messages (e.g., the SIP INVITE message) for establishing the communication session. The adaption changes/removes the one or more IP addresses to a different IP version to ensure proper IP compatibility.

    摘要： A communication processor receives a call request to establish a communication session from a first communication endpoint to a second communication endpoint. The communication processor changes the intent of the call request. For example, the call request can be changed by automatically forwarding the call request, automatically forking the call request, automatically rejecting the call request based on the second communication endpoint being busy, and/or changing a first type of medium of the communication session to a second type of medium of the communication session. A call log manager conveys status information regarding the changed intent of the call to a call log of the second communication endpoint based on changing the intent of the call request.

    摘要： To deal with ANAT/IP version incompatibility, a communication endpoint registers with a communication system using a SIP REGISTER message. For example, the communication endpoint registers when it boots up. The SIP REGISTER message indicates that the communication endpoint: does not support the Alternative Network Address Type (ANAT) protocol or is one of IPV4 intolerant or IPV6 intolerant. When a SIP INVITE message is received with a Session Description Protocol (SDP) offer that comprises the ANAT protocol or an IP address that is opposite of the IP version intolerance of the communication endpoint, a 4XX SIP response message is sent to the sender of the SIP INVITE to indicate the incompatibility. In response, to receiving the 4XX SIP response message, the SIP INVITE is modified to be compatible with the capabilities of the communication endpoint.

    摘要： A request for a communication session is received by a system. For example, a request to establish a voice communication session is received by the system. The system determines whether the request for the communication session is to be forked to a plurality of communication endpoints. If the communication session is to be forked, a highest bandwidth requirement for the forked communication session is determined. The determined highest bandwidth requirement for the forked communication session is based on a highest bandwidth requirement of one or more codecs that are defined in the received request for the communication session. The determined highest bandwidth requirement for the forked communication session is allocated so that the forked communication session can be established.

    摘要： To reestablish a media stream, first and second SIP INVITE with replaces header messages are received by an application from a first and second communication endpoint respectively. The SIP INVITE with replaces header messages comprises a first Session Description Protocol (SDP) offer that are each based a change of a network address used by the respective communication endpoint. In response to receiving one or both of the SIP INVITE with replaces header messages, the application, depending on implementation, sends one of a first SIP 200 OK message with a fabricated SDP answer or sends a SIP 480 temporarily unavailable message that does not comprise a SDP offer. This initiates the process of reestablishing the media stream on new network without dropping the communication session.
