SIP
Security Service

Through our sister company Redscan we provide SIP Security services developed by SiperaTM, recognised leaders in Unified Communications Security.

SIP Trunks are offered by Providers to connect an enterprise’s IP PBX to the traditional Public Switched Telephone Network (PSTN) over the Internet using the Session Initiation Protocol (SIP) standard.

Deploying SIP trunks enables enterprises to take full advantage of VoIP and eliminate costly Time-Division Multiplexing (TDM) trunks and TDM gateways. Enterprises route calls over the carrier’s IP backbone and use the same IP connection for all their communications.

Once enterprises decide to deploy one or more SIP trunks, however, they must address several important security and deployment issues. In particular, enterprises must consider the following security

Questions:

• Do the enterprise and the service provider have the same security requirements?
• Do the service provider and the enterprise have the same security policies for employees, networks, and VoIP system?
• How can the enterprise maintain control over signalling, media, security, and routing policies?
• How does the enterprise address new SIP or media threats to the enterprise infrastructure or to the service provider’s infrastructure?
• What changes must the enterprise make to the firewall/network address translation (NAT) device, IP PBX, private IP addresses, numbering plan, and other components?
• Must the enterprise network topology be exposed?
• How does the enterprise ensure user/caller ID privacy?
• How does the enterprise ensure the privacy of actual media communications?
• How is actual media privacy ensured? Is encryption required? If so, must it be end-to-end?
