Laying out VoIP based paging systems
• Start by realizing what VoIP is good for:
– Distances
– Interconnecting existing paging systems
– Bridging between different phone / paging systems

Laying out VoIP based paging systems
• Talk to the customer and determine:
–
–
–
–
Distances
Isolated areas where wireless could help
Existing paging systems they want to keep
Do they need “red” phones
• Page only emergency phones
• Ring down only emergency phones

Laying out VoIP based paging systems
• Talk to the customer and determine:
– How will they access the VoIP paging system
• Phone
• PBX
– FXO or FXS interface
• Microphone
– How many zones do they need
• Physical zones
• Logical zones
7/16/2015
Physical & Logical Zones
• 5 Floors
–
–
4 physical zones per floor
20 zones of speakers
• Floors 1 & 2 are grouped
together to make 1 logical zone
–
Consisting of 8 physical zones
• All floors are grouped for All Call
–
7/16/2015
20 physical zones of speakers
Laying out VoIP based paging systems
• Ask about the network environment:
– Are they running Novell
– Will there be routers / gateways between the paging
locations
– Does the network support Multicast
– Is DHCP available on the paging network
– Does the network have VLAN capability

Laying out VoIP based paging systems
• Based on the customers answers and job
requirements, the design will use one of two
families of products:
– Unmanaged
– Managed
7/16/2015
Laying out VoIP based paging systems
• Unmanaged device characteristics
–
–
–
–
–
–
Only programmed via setup tool
Functional on a Class “C” network only
Cannot be “pinged” on the network
Limited to 100 devices / page groups
Single audio channel devices only
External 24 Volt power supply
• Good for simple networks and smaller jobs
7/16/2015
Laying out VoIP based paging systems
• Unmanaged Part Numbers
– VIP-800 Page Port
• Connects to a page port or any line level output device
– VIP-810 Station Port
• Connects to a trunk port or analog phone
– VIP-820 Trunk Port
• Connects to an analog station port
(must provide open loop disconnect)

Laying out VoIP based paging systems
• Managed device characteristics
–
–
–
–
–
–
Programmed via Web browser and setup tool
Can be “pinged” on the network
Unlimited devices / page groups
1,2 and 4 channel devices
Firmware upgradeable via network
Operates on 802.3af PoE or dedicated -24Vdc
• Good for any network, any job

Laying out VoIP based paging systems
• Based on the customers answers and job
requirements, the design will fall into one of two
categories:
– Point to Point
– Distributed
7/16/2015
Laying out VoIP based paging systems
• Point to Point
– Used when multicast is not supported
– Cannot be used with DHCP assigned IP addresses
• Must assign static IP Addresses to all VoIP units
– Logical Page Zones must be provided by an external
page controller

Laying out VoIP based paging systems
• Point to Point example
– V-2924 providing Logical Page Zone control for 24
Physical Page Zones
– Each VIP-800 has a static IP address
– Each VIP-800 is programmed to connect to only the
VIP-800 at the far end of the page zone extension.
7/16/2015
Laying out VoIP based paging systems
• Point to Point
– Uses more network bandwidth than a distributed
system.
– Each audio connection will use bandwidth
7/16/2015
Laying out VoIP based paging systems
• Distributed
– Used when multicast is available
– Logical Page Zones provided via multicast network
protocol
– Can be used with DHCP assigned IP Addresses
– Most flexible

Laying out VoIP based paging systems
• Distributed example
– Big page control is gone
– IP addresses may be static or assigned via DHCP
– Each VIP-801 represents one physical page zone
• May also use VIP-802 or VIP-804 for multiple zones
– Logical Page Zones provided via multicast audio
