Up-to-Date

•SIP can be used with the MX-ONE™ Telephony Server. Features (such as callback and conference calls) are initiated in the same way as with analog telephones (suffix dialing).

•Media encrypted with SRTP (Secure Real-Time Transport Protocol) and signaling with TLS (Transport Layer Security)

•Security authentication with RADIUS servers using EAP (Extension Authentication Protocol), IEEE 802.1x.

•PoE (Power over Ethernet), IEEE 802.3af, Power Class 1, which means less than 4W required. This enables centralized power supply with the associated capability for power supply back-up.

•Compliant with the EU directive for RoHS (Restriction of Hazardous Substances).
