Gateway Selection Questions
When designing and deploying a Cisco AVVID solution, the selection of
a gateway for the environment will most likely be based on several criteria.
The following is a sample list of questions regarding required features
that should be asked prior to selecting a gateway:
Is an analog or digital gateway required?
What is the required capacity of the gateway?
Is it a standalone or IOS-based gateway?
Do you want an integrated all-in-one solution?
Is IP routing required?
What type of connection is the gateway going to use (analog
POTS, PSTN, or PBX connection)?
What types of supplementary services are desired?
Is voice compression a part of the design? If so, which types?
Is direct inward dialing (DID) required?
Is calling line ID (CLID) needed?
Is fax relay needed?
What type of network management interface is preferred?
To which country will the hardware be shipped?
Is rack space available for all needed gateways, routers, and
switches?
The need to verify equipment features and capabilities is constant
as Cisco continues to update the IOS software features and routers/
gateways listed in this chapter
