What Are the Benefits of CallManager?
Now that we have discussed the specifics dealing with the CallManager,
let’s discuss the benefits this system will afford your IP telephony solution.
As we know, CallManager is a software-based alternative to the
traditional PBX system. Traditional PBX systems have the ability to provide
an exceptionally high level of service. Cisco CallManager, utilizing
clustering technology, has the ability to offer almost these same levels of
service and in many cases, CallManager has proven to be an even more
reliable alternative to PBX systems. Because it is a distributed system,
your call processing functions are protected from a single point of
failure, ensuring that your calls can always be made, whereas a traditional
PBX system typically offers only a single point of failure.
So, what about the actual features that an administrator and enduser
can enjoy? Well, the list of what CallManager offers is quite impressive,
although some PBX systems may offer still more services. The list of
new services available to CallManager is growing almost daily and is
continually being revised and enhanced.
CallManager offers a system administrator the following: SNMP
registration, Call Detail Records (CDR), a distributed redundant database,
multiple Web-based administration consoles, Dialed Number
Identification Service (DNIS), enhanced 911 support, SNMP performance
monitoring, and several others.
CallManager offers the end-user the following: call connection and
administration, auto-answer of calls, hold and retrieve features, call forwarding,
call-park, calling line ID (CLID), Direct Inward Dial (DID), Direct
Outward Dial (DOD), distinctive ring service, and several others. This list is
growing almost daily as new releases of the software become available.
CallManager is one of the first and arguably the best systems of its
kind, offering administrators and end-users an all-in-one IP telephony
solution. Scaling from the smallest to largest organizations, it can meet
the challenge of almost any environment.
