Abstract: We describe a system embodiment comprising generating a Secure Real-Time Transport Protocol (SRTP) encapsulated packet and including a secure media indicator into the SRTP encapsulated packet. The method further comprises inserting the SRTP encapsulated packet into an SRTP voice stream associated with an active call between a source and a destination endpoint and indicating an end-to-end secure call between the source and destination endpoints responsive to the secure media indicator.And we describe a method embodiment comprising transmitting a request message from a source endpoint to a destination endpoint participating in an active call and setting a secure media flag in the request message at each node in a signaling path associated with the active call. The method further comprises returning a response message from the destination endpoint to the source endpoint responsive to the request and indicating an end-to-end secure call between the two endpoints.

Abstract: 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.

Abstract translation: 在特定实施例中，具有进度指示符的断开消息可以在网关的PSTN协议中被接收。 网关确定断开连接消息是否包含进度指示器。 然后，网关生成具有指示SIP消息从包括进度指示符的断开消息映射的原因指示符的SIP消息。 然后将SIP消息发送到第二个网关。 第二个网关确定SIP消息应该与断开消息互通。 第二个网关使用SIP消息中的原因指示符来确定这一点。 因此，第二网关将进程指示符断开连接发送到第二PBX。 这允许第二PBX的选项是收听带内公告或断开连接而不收听带内公告。

Abstract: 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.

Abstract: In one embodiment, a first end device associated with a first user and a second end device associated with a second user may be participating in a call. During the call, the second user may wish to transfer the call to a third user. The second user has the choice of using a blind transfer or a consult transfer. In one embodiment, a gateway determines interworking information that is needed to interwork an H.450.2 message for the H.323 protocol to a SIP REFER message, and vice versa, to allow the call transfer.
