Meanwhile, the dual 10/100 Mbps network ports with integrated PoE makes T21P E2 an ideal choice for extended network use. The T21(P) E2 supports two VoIP accounts, simple, flexible and secure installation options, plus support for IPv6, Open VPN and a redundancy server. It also operates with SRTP/ HTTPS/ TLS, 802.1x.
