Abstract: Disclosed are a method, apparatus and system for interworking between H.320 or H.324 and SIP. The method comprises receiving a SIP message indicative of capabilities supported by a first endpoint device and deferring responding to the SIP message. The method further comprises receiving from a second endpoint device an H.320 or H.324 message indicative of the capabilities supported by the second endpoint device in response thereto responding to the SIP message thereby to establish a media communication channel between the first and second endpoint devices based on their respective capabilities.

Abstract: A system and method for consolidating media signaling to facilitate IP telephony includes receiving a first message exchange in a first protocol from a first endpoint to negotiate a media path with a second endpoint. It is determined to consolidate the first message exchange with additional message exchanges received from the first endpoint in the first protocol. A second message exchange is received in the first protocol from the first endpoint, and information derived from the first message exchange and the second message exchange is consolidated. A first message exchange in a second protocol is initiated to the second endpoint according to the information consolidated from the first and second message exchanges in the first protocol. One or more media flows is facilitated over the media path between the first and second endpoint s according to the first and second message exchanges in the first protocol and the first message exchange in the second protocol.

Abstract: Embodiments of the present invention provide techniques for refreshing a session. A session is refreshed using a refresh message that is enhanced for a refresh. For example, the refresh message does not include an SDP or any other message body. The message includes only a reduced header. This reduces time spent building and parsing the refresh message. Also, less bandwidth is used in sending the refresh messages.
