Introduction

Using multicast, any number and combination of Algo products can be activated simultaneously, including

Algo speakers, paging adapters, and strobes.

Any Algo SIP endpoint speaker, paging adapter or strobe can be configured as either "Master" or "Slave"

for multicasting purposes. Only the Master endpoint speaker is registered to the telephone system. Slave

devices do not require registration. This minimizes the costs associated with additional endpoint

extensions in a hosted environment, or SIP licensing which may be required with a premise-based

telephone system.

This document provides detailed instructions for some example applications. These can be used as a

template for creating endless other combinations.

Note: RTP is the Multicast Mode referenced throughout this guide, however, Polycom Group Page,

Singlewire InformaCast and Syn-Apps SA-Announce are also supported. For additional information on

configuring other multicast modes please reference Algo product user guides and Polycom Solutions

Guides.

Example #1: Algo 8188 Master to 8188 Slave

This example shows how two or more 8188s can be paged simultaneously in order to cover a large area

with voice paging.

1) Configure 8188 as Master

a. Log into the web interface by typing the device’s IP address in the browser. The address

assigned by the DHCP server may be discovered by pressing the reset switch (RST next to

the light) to hear it over the speaker. The IP address may also be discovered by

downloading the Algo Locator Tool to find Algo devices on your network:

www.algosolutions.com/locator. If the attempt to obtain an IP address from the DHCP

server is unsuccessful it will default to 192.168.1.111 (contact your network administrator

for assistance).

b. Log in with the default password “algo”.

c. Click on Basic Settings tab and then SIP tab. Enter the SIP server name or IP address in

the SIP Domain (Proxy Server) field. Enter a unique Page and/or Ring Extension,

Authentication ID and Authentication Password to register the 8188 with the SIP Server.

At the bottom of the screen click Save.

Note: If Page only is required, then the Ring Extension fields can be left blank. On the Page

Extension, the device will auto-answer. On the Ring Extension, the device will play a WAV

file of your choice.

d. Navigate to Basic Settings -> Multicast and check the “Master/Sender” option in

Multicast Mode. Make sure the “Master Single Zone” drop-down list is set to Zone 1. Hit

save.

e. Advanced multicast configurations can be found under Advanced Settings -> Advanced

Multicast. For typical setups, the default settings should be used.

2) Configure 2nd 8188 as Slave

a. Repeat steps a. and b. as described above.

b. There is no need to register this device with the SIP server, as it is only acting as a Slave

listening to multicasts.

c. Navigate to Basic Settings -> Multicast and check the “Slave/Receiver” option in

Multicast Mode. Make sure Zone 1 is selected on Basic Slave Zones setting. Hit save.




3) Test it! Make a call to the page extension setup in the 8188 Master device. Both, the Master and

Slave devices should page simultaneously.

Note: Any number of additional 8188 devices, or other combinations of Algo endpoints such as

8128/8180/8186/8201/8301/8373, can also be configured as slaves, allowing the voice page to reach an

entire building, campus or enterprise.




Example #2: Algo 8301 Master to 8180 Slave & 8128 Slave

This example shows how an 8301 can be used as a master device, in order to page to a variety of different

slaves. The 8301 master device can be stored in a secure location (e.g. a server room) to ensure that it

cannot be tampered with.



assigned by the DHCP server may be discovered by pressing the reset switch to hear it

over the analog outputs (e.g. headset can be connected to the “aux out” port). The IP

address may also be discovered by downloading the Algo Locator Tool to find Algo devices

on your network: www.algosolutions.com/locator. If the attempt to obtain an IP address

from the DHCP server is unsuccessful it will default to 192.168.1.111 (contact your

network administrator for assistance).


c. Click on Basic Settings tab and then SIP tab. Enter the SIP server name or IP address in

the SIP Domain (Proxy Server) field. Enter a unique Page and/or Ring Extension,

Authentication ID and Authentication Password to register the 8301 with the SIP Server.

At the bottom of the screen click Save.

Note: If Page only is required, then the Ring Extension fields can be left blank. On the Page

Extension, the device will auto-answer. On the Ring Extension, the device will play a WAV

file of your choice.





d. Navigate to Basic Settings -> Multicast and check the “Master/Sender” option in

Multicast Mode. Make sure the “Master Single Zone” drop-down list is set to Zone 1. Hit

save.

e. Advanced multicast configurations can be found under Advanced Settings -> Advanced


2) Configure 8180 as Slave

a. Use the web interface tool to setup the 8180 by entering the device’s IP address into a

browser. To find it, press the Menu button until the option for “get device info” is reached.

Then press select to hear address.

Alternatively use the Algo Locator Tool to find devices on your network:



for assistance).

b. Log in with the default password “algo”





c. There is no need to register this device with the SIP server, as it is only acting as a Slave


d. Navigate to Basic Settings -> Multicast and check the “Slave/Receiver” option in

Multicast Mode. Make sure Zone 1 is selected on “Slave Zones” setting. Hit save.

e. The master's volume is set separately for ring and page. The slave volume, when receiving

a stream from the master, whether due to a ring or a page, is set with page volume. To

adjust it, navigate to Basic Settings -> Page tab, update Page Volume option accordingly

f. Advanced multicast configurations can be found under Advanced Settings -> Advanced


3) Configure 8128 as Slave

a. Use the web interface tool to setup the 8128 by entering the device’s IP address into a

browser. The IP address may be discovered by downloading the Algo Locator Tool to find

Algo devices on your network: www.algosolutions.com/locator. If the attempt to obtain

an IP address from the DHCP server is unsuccessful it will default to 192.168.1.111

(contact your network administrator for assistance).






c. There is no need to register this device with the SIP server, as it is only acting as a Slave



Multicast Mode. Make sure Zone 1 is selected on “Slave Zones” setting. Hit save.

4) Test it! Make a call to the ring and/or page extension setup in the 8301 Master device. The 8180

should ring or page and simultaneously the 8128 LED should strobe/pulse (depending on

configuration).

Note: Any number and combination of Algo endpoints can be configured in a multicast to include:

8128/8180/8186/8188/8201/8301/8373.




Example #3: Multicast Zoning

This example illustrates a scenario where there are 2 buildings with a total of 4 Algo SIP endpoints

distributed among them.

Requirements:

• Each endpoint must be available to be individually paged

o This is accomplished by having unique page extensions configured on the slaves (i.e. 2012,

2021, 2022)

o 8301 Master (MAIN-UP) is connected to an amplifier with speakers distributed

throughout the 2nd floor of the main building

• Building wide paging

• Company wide paging

The table below provides more details of the environment as well as a set up that would fulfill the

requirements. Please note that there are multiple ways to achieve these requirements and different

extension numbers could be used instead.

Device Name

Extension Location/Description Model Multicast

Mode

Main Building (Zone 1)

MAIN-UP

2000 All Call Zone - Company Wide

8301 Master

2010 Zone 1 - Main Building

2020 Zone 2 - Warehouse

2011 Priority Call Zone - Main Building

(Upstairs - Connected to Amp)

MAIN-DOWN

2012 Main Building - downstairs 8186 Slave

Warehouse (Zone 2)

WARE-UP 2021 Warehouse - Upstairs 8186 Slave

WARE-DOWN

2022 Warehouse - Downstairs 8180 Slave

Note: zone naming (Music, All Call, and Priority Call) is defined as a convenience to the person doing the

configuration. They are just zones, and may be used for any purpose, as can any of the other zones.




1) Configure 8301 (MAIN-UP) as Master

a. To access the web interface, reference Example #2, item 1, part a & b

b. Click on Basic Settings tab and then SIP tab. Enter the SIP server name or IP address in

the SIP Domain (Proxy Server) field. Enter Page Extension #2000 (All Call), Authentication

ID and Authentication Password to register the 8301 with the SIP Server. At the bottom

of the screen click Save.

c. Navigate to Basic Settings -> Multicast and check the “Master/Sender” option in

Multicast Mode. Make sure the “Master Single Zone” drop-down list is set to All Call. On

Speaker Playback Zones, select Priority Call, All Call, and Zone 1, as we want the master

device to play audio for selected zones only (through amplifier). Hit save.




d. Click on Additional Features -> More Page Extensions Tab. Enable 3 additional page

extensions, as per the table above. Extension 2011 will be used for paging the 8301

master only (there will be no units listening to this zone – Priority Call Zone). Add

extension 2010 (all call for Zone 1) and 2020 (all call for Zone 2). Save changes.

2) Configure 8186 (MAIN-DOWN) as Slave


assigned by the DHCP server may be discovered by connecting the reset terminals on the

back of the unit to hear it over the speaker. The IP address may also be discovered by

downloading the Algo Locator Tool to find Algo devices on your network:



for assistance).


c. Click on Basic Settings and then SIP Tab. Enter the SIP server name or IP address in the

SIP Domain (Proxy Server) field. Enter Page Extension #2012, Authentication ID and





Authentication Password to register the 8186 with the SIP Server. At the bottom of the

screen click Save.


Multicast Mode. In “Basic Slave Zones” check All Call and Zone 1. Hit save.

3) Configure 8186 (WARE-UP) as Slave

a. To access the web interface, follow steps a and b from item 2 above

b. Click on Basic Settings tab and then SIP Tab. Enter the SIP server name or IP address in

the SIP Domain (Proxy Server) field. Enter Page Extension #2021, Authentication ID and


screen click Save.






4) Configure 8180 (WARE-DOWN) as Slave


b. Click on Basic Settings tab and then SIP tab. Enter the SIP server name or IP address in

the SIP Domain (Proxy Server) field. Enter Page Extension #2022, Authentication ID and


screen click Save.




Example #4: Multicast Zoning with DTMF Selectable Mode

This case implements the same scenario described in the example above, but with the use of DTMF

Selectable Zones. DTMF Selectable Mode offers a dynamic page zone selection and requires only the

Master device to have a registered SIP Extension. To page, dial the SIP extension of the Master device and

then dial the desired DTMF page zone (e.g. 1, 2, etc.) on the keypad. This feature does not require the use

of multiple extensions, like seen in Example #3.

Device Name Zone/DTMF Location/Description Model Multicast

Mode

Main Building (Zone 1)

MAIN-UP Extension

2000

All Call (DTMF:0) Company Wide

8301 Master

Zone 1 (DTMF:1) Main Building

Zone 2 (DTMF:2) Warehouse

Priority Call (DTMF:9)

Main Building (Upstairs - Connected to Amp)

MAIN-DOWN Zone 3 (DTMF:3) Main Building - downstairs 8186 Slave

Warehouse (Zone 2)

WARE-UP Zone 4 (DTMF:4) Warehouse - Upstairs 8186 Slave

WARE-DOWN Zone 5 (DTMF:5) Warehouse - Downstairs 8180 Slave

Please reference page 11 for full scenario description.

Below is a table with correlation between the zone and its respective DTMF code. For Basic and Expanded

Zones, reference the Advanced Settings -> Advanced Multicast page.

Note: DTMF codes for zones 10 and higher start with an “*”.

1) Configure 8301 (MAIN-UP) as Master


b. Click on Basic Settings and then SIP tab. Enter the SIP server name or IP address in the SIP

Domain (Proxy Server) field. Enter Page Extension #2000, Authentication ID and


screen click Save.


Multicast Mode. Enable DTMF Selectable Zone in Zone Selection Mode. On Speaker

Playback Zones, check Priority Call, All Call, and Zone 1, as we want the master device to

play audio for selected zones only (through amplifier). Hit save.

Note: With "DTMF Selectable Zone", the Master Single Zone setting will not apply to

Paging (since the zone can now be dynamically selected per call using DTMF), but it will

still apply to the Ring Extension and Relay triggered events, including the analog audio

input.




2) Configure 8186 (MAIN-DOWN) as Slave


b. Navigate to Basic Settings -> Multicast and check the “Slave/Receiver” option in

Multicast Mode. In “Basic Slave Zones” check All Call, Zone 1 and Zone 3. Hit save.




3) Configure 8186 (WARE-UP) as Slave




4) Configure 8180 (WARE-DOWN) as Slave







Example #5: Bell Scheduler and Emergency Alerts for School

This example illustrates a school which requires multiple page zones, emergency alerting and bell

scheduling. Multiple endpoint speakers and strobes will be used across the building environment. The bell

scheduler will be for automated tones (e.g. morning, lunch, end of day and recess breaks) and emergency

alerts configured for Shelter and Lockdown announcements.

Below are details of the environment, devices, and proposed zoning. Please note that there are alternative

ways to achieve these requirements, however, multicast page zones have been configured on different

extension numbers for user convenience.

• Zone 1 (8188’s) – Hallways, common areas, admin office

• Zone 2 (8180’s) – Classrooms + unique extensions for individual classroom paging & talkback

• Zone 3 (8186’s) – Gym & outdoor playground

• All Call Zone (All units, except for 8128’s strobe) – School wide paging

• Priority Call Zone (All units + 8128's) – Emergency notifications (e.g. Lockdown and Shelter)

Custom Multicast IP Address and Port Number

Custom Multicast IP address and port number can be set for each zone. To update the default addresses,

navigate to Advanced Settings -> Advanced Multicast. Make sure the address is within the range below

and Master and Slaves are configured in a similar way.

• Multicast IP addresses range: from 224.0.0.0 to 239.255.255.255

• Port numbers range: 1 to 65535

Default Multicast IP address: 224.0.2.60 port numbers 50000 – 50008

Note: Make sure that the multicast IP address and port number do not conflict with other services and

devices on the same network.




Troubleshooting

Configuration Problems

The most common issues that may cause a problem with Multicasting between Master and Slaves are

described below. Make sure the following settings match your device’s configuration (dependant on

Multicast Mode setup).

• Multicast Mode (located in Basic Settings -> Multicast)

➢ Master = Master/Sender

➢ Slave = Slave/Receiver

• Multicast Type (located in Basic Settings -> Multicast)

➢ Master = Regular/RTP

➢ Slave = Regular/RTP

• Zone Number (located in Basic Settings -> Multicast)

➢ Ensure the Zone # that is selected on the Master is also ticked on the Slave. A proper

configuration will ensure the Slave is listening to the Zone where the Multicast packets

are being sent.

• Zone Definitions (located in Advanced Settings -> Advanced Multicast)

➢ Ensure the IP Address and Port # matches, on both the Master & Slave, for the zone that

is being used.

Network Related Problems

If the configuration on the Master and Slave devices is correct, any remaining problem should be related

to the network. Below are some issues to be aware of:

• Ensure all devices in the Multicast Zone have IP addresses on the same subnet;

• Assure all devices are in the same VLAN;

• Confirm all devices are reachable by pinging them;

• Make sure the network switches have Multicast enabled.

Scenario: multicast works when all units are connected to the same switch, but it does not when going

through the network to a different switch

✓ Multicast masters use a TTL (Time to Live) of 1. This can be modified to allow more hops, thus

avoiding the packet being dropped as it navigates to its destination




✓ To adjust this setting, navigate to System -> Maintenance -> Download Configuration File. In that

file, look for “mcast.master.ttl” and set it to a value sufficient to handle the number of hops

required. Save the file and upload it back to the unit.
