Using AVVID Applications in
IP Telephony Single Site Solutions
.. Single site VoIP systems can be a cost-effective replacement for
traditional PBX systems, especially in locations where available PBX
solutions are limited.This is most helpful in places where you have more
network engineers capable of managing Cisco devices than traditional
telephony solutions.
.. VoIP permits easy remote management of the entire system via
CallManager’s Web interface. Even the server’s services can be stopped
and restarted by way of the Web interface.

386 Chapter 10 • Designing and Implementing Single Site Solutions
.. By using the inline power enterprise model of switches, the customer
can future-proof growth needs for both voice and data applications,
foregoing the need for replacement devices and the consequent
disruption of existing services.
Chapter 10 explored the usefulness of VoIP and a few AVVID solutions in a small
site environment.You’ve seen how sites can be designed from scratch, and modified
from an existing infrastructure.These two options contain many issues of
merit, including addressing the usage of mixed vendor network electronics within
the same Ethernet network.
CallManager is the IP version of a PBX system.You got a brief preview of
how to install and configure CallManager, how to use it for flexibility purposes
when creating and managing IP phones, and how your mobile users can still
benefit from VoIP by using the Cisco IP SoftPhone. Since VoIP mandates a reasonable
return on investment to justify the capital expenses, we discussed how
you can gain significant ease of administration (both locally and remotely) and
flexibility for handling short notice phone changes.
Lastly, we showed how Cisco’s AVVID solutions are a boon when distributing
information to a large audience by using the IP/TV and IP/VC solutions, which
can significantly reduce travel expenses and shorten the time to deliver presentations.
You can host very short notice meetings, whiteboarding discussions, and oneon-
one conferences with very little cost beyond the initial installation and testing.
In Chapter 11, we’ll expand on these topics to cover multiple sites and a
larger campus enterprise.
