II. Rack Space Requirements

You should make sure that all IPT components have required rack space available for the installation. The rack space requirement varies depending on the type of server, switch, or router. You should obtain the number of rack units required to mount each hardware device. Refer to the vendors' product documentation to obtain this information.

Cat 5

2

What are the T1/E1 line terminations for connecting the voice circuits?

Site:

Building:

Floor:

3

What are the locations of analog line terminations?

Site:

Building:

Floor:

4

Is distance between the telco termination and the voice gateway in acceptable range?

Yes

No

Distance in feet:

IV. Power and HVAC Requirements

1

Are the power requirements met, as evaluated in the planning phase?

Power calculator:

http://www.cisco.com/go/powercalculator

Yes

No

2

Can HVAC systems take the additional load of the equipment?

Yes

No

3

Does the site have proper grounding for the equipment?

Yes

No

I. Voice Circuit Analysis

1

Is the interfacing equipment required for integration of PBX, voice-mail, and ACD systems with CallManager available?

Yes

No

2

Do the software versions that run on the PBX, voice mail, and other equipment requiring integration support CallManager?

Yes

No

3

If moving the PSTN circuits from the PBX to the IPT system, does a different telco interface need to be requested?

Yes

No

4

Who are the contacts for the PBX, voice-mail, and ACD systems? You might have to obtain a list of additional contacts, depending on need. This staff should have access rights to make congigurations changes.

PBX system contact name:

Work phone:

E-mail:

Cell phone:

Voice mail system contact name:

Work phone:

E-mail:

Cell phone:

ACD system contact name:

Work phone:

E-mail:

Cell phone:

5

Did you place the order with the telco to terminate the new voice circuits?

Yes

No

6

If you plan to migrate users from the PBX system to the IPT system, have you grouped the identified users?

Yes

No

I. LAN Analysis

1

Are the switch ports on the LAN switches enabled?

Are required QoS configurationssuch as auxiliary VLAN, port trusts, speed/duplex, inline power, and recommended software versionscompleted to connect the IP Phones, servers, and voice gateways?

Yes

No

Yes

No

2

Is the DHCP server configured with all the scopes, correct default gateways, DHCP option 150 or 66, and DNS values?

Yes

No

3

Is the IP helper address configuration that was completed on the routed interface pointing to the right DHCP server for each IP Phone VLAN segment?

Yes

No

4

Did you provide the list of server names and IP addresses to the administrators of the DNS servers?

This is required so that DNS servers can resolve the names of the voice servers properly. It is always better to do this in advance because the DNS replication process takes a few hours to replicate the information to all the servers in the network.

Yes

No

II. WAN Analysis

1

Are the WAN routers running the right Cisco IOS software to support the required QoS feature set?

Yes

No

2

Is the configuration on the WAN routers in accordance with QoS recommendations to transport the voice traffic in the priority queue?

Yes

No

3

If a gatekeeper is required for CAC, is it rack mounted, loaded with the right Cisco IOS software, and configured?

Yes

No

4

Do the WAN routers have sufficient DRAM?

Yes

No

5

Are the route-trip delay times between the central and branch sites within the acceptable range to achieve good quality on voice calls?

Yes

No
