Cmterm 7941 7961 — Sip 8 5 4 Zipl

Security is a paramount concern in enterprise voice networks, and cmterm-7941_7961-sip.8-5-4 introduced necessary hardening features. This version provides enhanced support for Transport Layer Security (TLS) for SIP signaling and Secure Real-time Transport Protocol (SRTP) for media encryption. This capability allows organizations to deploy the 7941 and 7961 models in environments requiring strict regulatory compliance, such as healthcare or finance, without exposing voice traffic to interception. Furthermore, the firmware improved the handling of certificates, allowing the phones to better authenticate against modern servers, a requirement that earlier 8-2-x and 8-3-x builds struggled with in secure environments.
