摘要: In one embodiment, a method includes receiving at a protocol translator a first message from a first endpoint to a second endpoint. The first message includes a list of media capabilities of the first endpoint. The method also includes transmitting from the protocol translator a second message to the second endpoint including a media capabilities request header and receiving at the protocol translator a response message from the second endpoint. The response message includes a response header including a list of the media capabilities of the second endpoint.

摘要: In a particular embodiment, a disconnect message with a progress indicator may be received in a PSTN protocol at a gateway. The gateway determines if the disconnect message includes a progress indicator. The gateway then generates a SIP message with a reason indicator that indicates the SIP message is mapped from a disconnect message that includes the progress indicator. The SIP message is then sent to a second gateway. The second gateway determines that the SIP message should be interworked to a disconnect message. The second gateway uses the reason indicator in the SIP message to determine this. Accordingly, the second gateway sends a disconnect with progress indicator to a second PBX. This allows the second PBX the option to either listen to an in-band announcement or to disconnect without listening to the in-band announcement.

摘要: In one embodiment, a session is refreshed using a message that is simplified for refresh purposes. The refresh message that is used is a message used for another purpose in a protocol (e.g., SIP). For example, a reINVITE message may be used as a refresh message. If the reINVITE message is used for its intended purpose, the reINVITE message may be used to change the characteristics of a session. This reINVITE message includes an SDP and full header such that the parameters can be properly changed. However, the reINVITE message may be used to refresh a session. This may be referred to as a simple refresh message. But, the simple refresh message does not include an SDP or any other message body. The simple refresh message includes only a reduced header. This reduces time spent building and parsing the simple refresh message.
