Troubleshooting Voice over IP
The emergence of Voice over IP (VoIP) as the new standard for
business telephone systems has been confirmed by marketing
data that shows revenue generated by IP-based PBX lines has
surpassed conventional time domain multiplexing (TDM) lines in
percentage of worldwide revenue. The penetration of VoIP in the
residential market is deepening quickly. A key driver of this rapid
adoption rate is triple-play service offerings from providers
offering phone service at a low incremental cost. Potential
customers are initially attracted to VoIP by its low price but tend to
stay with the service when they grow accustomed to its advanced
features such as Web-based call logs, click-to-dial and virtual
phone numbers.
Understanding VoIP Equipment and Protocols
The customer premises equipment (CPE) for a VoIP subscriber can
consist of either a traditional POTS phone that plugs into a
terminal that converts signals to VoIP or a phone with native VoIP
support that can connect directly to an IP network. The server
supports the routing of calls across the network and provides
management functions. The IP network provides connectivity
between the terminals.
