Integrated Secure Voice Managed Services

Integrated Secure Voice Managed Services enable various voice and video applications behind Enterprise Class Teleworker enabled CPEs (ie: remote router) within a secured network. While firewall ACL in ECT-enabled CPE will block anything needed for these voice services (except the control messages). Other security features (ie: NAC, 802.1x, Authentication Proxy) should also bypass authentication confirmation from VoIP phones. Firewall inspection will open necessary ports to permit voice traffic after a call has been initiated. Quality of Service must be initially enabled for voice traffic, based on uplink bandwidth available from the ISP. The bandwidth usage depends on the codec; the most popular codecs are G.729 and G.711.
