摘要： In a particular embodiment, a network device receives, from a first device, a first call request for a second device. The network device may then send the first call request to a redirect server, which can determine where to send the call. The network device receives a response from the redirect server indicating an address to redirect the call request to. The network device then determines a redirect ID for the redirect. The network device sends a message to the first device with the redirect ID where the message indicates that a redirection occurred to the third device. The network device then receives a second call request from the first device that includes the redirect ID. The network device determines if the call was part of a previous redirect. If so, the second call request is sent to the address associated with the redirect ID.

摘要： 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.

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.
