With the advent of the voice over internet protocol (VoIP) and associated devices, it's good to know that all of our IP-type products are capable of carrying such traffic - carrying the dialtone if you will - to remote locations.

From the IP920LC through to the VIP series products, VoIP traffic may be carried in an ascending amount of volume. For those 'leaner' links, where VoIP may be a priority over serial data (for example), utilize our quality of service (QoS) feature to specify which data port - or protocol - has the highest priority.
