Frequently Asked Questions

I am hearing a lot about Voip. What is Voip? Is there a cost benefit to moving from a legacy analog and digital voice platform to Voip?
Voice over Internet Protocol, also called VoIP, IP Telephony, Internet telephony, Broadband telephony, Broadband Phone and Voice over Broadband is the routing of voice conversations over the Internet or through any other IP-based network. Since phone calls are converted to digital packets sent across a network and reassembled on the terminating end, some cost savings can be achieved by utilizing a single network for voice and data especially where an enterprise has existing underutilized network capacity that can carry VoIP at a cost beneficial to the users.

What are the effects of latency in Voip? Given that latency is the time it takes a packet to reach a destination, and VoIP is a packetized conversation, latency in regard to a VoIP transmission is the time it takes a spoken word to reach its destination once spoken. If network latency is high the listener will hear the words and acknowledge the speaker later than a normal conversation and an unnatural cadence of the conversation may occur. Jitter, a close cousin of latency, is the variance in time that packets arrive to be assembled into a word and heard. If jitter is high, words will be broken and segmented. At this point, the communication has failed.

What are the advantages of Wide Area Ethernet? Ethernet Services are data networking services that allow you to connect LANs within and between metropolitan areas in a simple, cost-effective way. Unlike T1 / T3 private lines, frame relay or ATM networking, they are simpler to manage because you can treat all your connected LANs as one large network, even across the country. They are easier to set up because you only need a standard LAN connection plug. They are lower in price because you no longer need to purchase expensive dedicated circuits and additional customer-owned transport equipment to connect sites. Because Ethernet Services are so simple to maintain, you no longer need a large technical support staff to realize the benefits of a broadband LAN interconnection. And they can be provisioned quickly since no local loop connection is required.
