SIP and IP support Blueworx Voice Response supports IPSEC on signaling information. IPSEC is a method of making internet protocol as secure as possible by using, authentication, integrity checking, and encryption.
Session timer RFC4028 defines the SIP Session Timer mechanism (which is a way to prevent SIP sessions hanging up indefinitely). A brief description of its operation is as follows:
Communicating over SIP with a switch using DTMF digits Normally, DTMF digits are communicated over the RTP (Media) stream using either inband (audio) or payloads (RFC2833). The problem in this case is that, with SIP, the media flow is between endpoints (the caller/called and Blueworx Voice Response) whereas the information needs to be sent to or received from a switch. The only way to do this is using the SIP Signalling path and the only defined way to do this is by using the SIP INFO method defined by RFC2976.
