Preparing to Conﬁgure the Software

Before you can conﬁgure your Cisco AS5300 to use VoIP, you must ﬁrst complete the tasks listed

below. If your Cisco AS5300 is already conﬁgured to use VoIP, you can skip this section.

To conﬁgure your Cisco AS5300 to use VoIP:

• Establish a working IP network. For more information about conﬁguring IP, refer to the

“IP Overview,” “Conﬁguring IP Addressing,” and “Conﬁguring IP Services” chapters in the

Network Protocols Conﬁguration Guide, Part 1.

• Complete basic conﬁguration for the Cisco AS5300. This includes, as a minimum, the following

tasks:

— Conﬁgure a host name and password for the Cisco AS5300.

— Conﬁgure Ethernet 10BaseT/100BaseT interface of your Cisco AS5300 so that it is

recognized as a device on the Ethernet LAN.

— Conﬁgure Cisco AS5300 interfaces for ISDN PRI lines.

— Conﬁgure ISDN D channels for each ISDN PRI line.

For more information about these conﬁguration tasks, refer to the Cisco AS5300 Universal

Access Server Software Conﬁguration Guide.

• Install the VoIP card (VFC) into the appropriate slot of your Cisco AS5300 access server. Each

VFC can hold up to ﬁve digital signal processor modules, enabling processing for up to 30 B

channels with single-density DSPs or 60 B channels with double-density DSPs.

• Complete your company’s dial plan.

• Establish a working telephony network based on your company’s dial plan.

• Integrate your dial plan and telephony network into your existing IP network topology. Merging

your IP and telephony networks depends on your particular IP and telephony network topology.

In general, we recommend the following:

— Use canonical numbers wherever possible. It is important to avoid situations where

numbering systems are signiﬁcantly different on different routers or access servers in your

network.

— Make routing and/or dialing transparent to the user by, for example, avoiding secondary dial

tones from secondary switches, where possible.

— Contact your PBX vendor for instructions on how to reconﬁgure the appropriate PBX

interfaces.
