Here's a neutral and interesting summary of the text in one paragraph: Secure Trunking, now generally available on Elastic SIP Trunks from Twilio, enables businesses to encrypt media and signaling using Secure Real-time Protocol (SRTP) and Transport Layer Security (TLS), ensuring secure communications. This feature is particularly important for companies with strict information security practices. With Secure Trunking, encryption allows businesses to use SIP trunks and cloud communications while maintaining the benefits of both, such as cost savings and flexibility in utilization. The service provides robust authentication and encryption, enabling enterprises to deploy SIP Trunking at scale and ensuring secure communication.
