announces the release of Fusion SIP version 5.0 for secure VoIP telephony. With this release, Fusion SIP now supports SIP over TCP/IP and secure SIP or SIPS. SIP is one of the signaling protocols most commonly used in VoIP telecommunications. SIPS is the security-enhanced implementation of SIP. Fusion SIPS provides secure SIP for telecommunications by allowing an IP telephone to encrypt all data transmissions between a SIP Proxy and the phone. Encrypting SIP transmissions is vital as more and more users move from POTS to the Internet alternative, VoIP.
Of particular interest to developers, this release of Fusion SIP was tested against the Protos test suite and passed all 4000+ cases. The Protos test suite focuses on the parsing of INVITE messages and verifies that the device can correctly parse the many different permutations of invalid SIP header fields.
