Twilio has announced two new features for its Programmable Voice SIP Interfaces: Secure media using SRTP (Secure Real-time Protocol) and Emergency Calling capability for SIP Endpoints. These features aim to enhance security and emergency calling capabilities for contact centers, allowing agents to use SIP phones to make emergency calls while securing communications with SRTP encryption. With the Emergency Calling feature, Twilio routes calls to the nearest Public Safety Answering Point (PSAP) to get help in case of an emergency, while Secure media uses SRTP to encrypt media traffic and protect it from hackers and cybercriminals.
