Quality Standards
Wahsega Labs products achieve the highest standards of
performance in the market by utilizing our complete quality
assurance program encompassing software testing, product design
and a multistage automated factory test program.
Wahsega Labs’ ultimate goal is to provide a solution that is both cost
effective and unsurpassed in quality. By leveraging existing
relationships with suppliers to guarantee premium components at the
lowest possible prices, we are able to ensure Wahsega Labs products
are the finest quality in the market while still offered at highly
competitive prices directly to installers.
In order to achieve the greatest possible voice clarity, all voice and
related algorithms have been individually tested to ensure the highest
potential MOS score. The accumulated error syndrome, which can
cause poor voice quality, is mitigated through this testing process.
Wahsega Labs’ engineering team utilizes a wide array of dedicated test
servers to pull and build the various software projects multiple times
per day. Each automatic build is then run through an extensive set of
automated test cases to ensure the highest performance of each and
every firmware version released. This test case coverage is expanded
on a continual basis.
All Wahsega Labs products are 100% factory tested at the board level
through a bed of nails full functional test, not just an “is it close
enough?” flying probe test. Every finished product is 100% tested again
after the final assembly via an automated test station to ensure the
highest production quality product for installers.
To assure the highest quality standards, all Wahsega Labs products are
designed, developed and manufactured in the USA.

User Experience
The Wahsega 2x2 Ceiling Speaker with SIP may look like a standard 2x2
ceiling tile speaker, but it can receive audio from multicast IP broadcasts or
from a SIP PBX, and it can act as an intercom for two-way conversations
with the help of its built-in microphone.
The speaker may also be connected to a panic button to make emergency
SIP calls and/or to a remote wall panel to access classroom sound
reinforcement functions. Its two onboard relays can be controlled
remotely to operate door locks for up to two doors per classroom.
In addition, a second, auxiliary speaker may be connected up to 20 meters
away via Ethernet cable. This auxiliary speaker—which is powered by the
first speaker—can be either in the same classroom as the primary speaker
or in a separate classroom. Although powered the same way, these two
applications function differently.
In a single-classroom application, the auxiliary speaker acts as a
companion to the main speaker. The auxiliary speaker’s volume can be
adjusted independently, but it will always broadcast the same audio as the
main speaker. In this application, the primary speaker controls features
such as door locks, microphone, panic button and sound reinforcement.
In a two-classroom application, the auxiliary speaker has its own SIP
account, enabling it to send and receive audio independent of the main
speaker. It functions separately from the primary speaker, controlling door
locks, microphone, panic button, and sound reinforcement of its own. To
an end user, the auxiliary speaker appears to be completely autonomous;
it is simply powered by the primary speaker.

www.wahsega.com Page 7
Once your speaker is installed and configured, you will be able to receive
SIP calls with no additional in-room setup. Two-way communication is
clear and simple with a built-in microphone which transmits audio from
the classroom to the caller.
If a panic button is connected to the speaker, it will make an emergency
call to a preset SIP number on the PBX. To reduce the incidence of false
panic calls, the panic button has two call modes: short press and long
press. The short press call—which is a call placed after the button is
depressed for any length of time less than two seconds—calls a first,
preconfigured number, such as a front office. The long press call—a call
placed after the button is depressed for two or more seconds—calls a
second, preconfigured emergency number, such as 911.
If the installation includes a sound reinforcement wall panel, that panel
will also have an audio input, volume control, activate button and LED
indicator light.

Software Capabilities
The speaker’s configuration is accessible using an HTTP Web interface,
viewable from any Web browser on the same LAN. This allows access to
various settings such as network/IP address, SIP account configuration,
RTP multicast broadcast configuration, intercom/speaker behavior, panic
button call numbers, and administrative functions such as firmware
upgrade and configuration backup/restore. The configuration is stored in
a .JSON file, which is human readable and can be edited by site
administrators.

www.wahsega.com Page 9
Getting Started
1. Connect the speaker’s main Ethernet port—labeled POE—to a
network using a Power-over-Ethernet (PoE) Ethernet connection.
When connected, it will power on immediately, and the LINK/ACTV
LED on the Ethernet port will begin to blink.
2. Locate and note your speaker’s MAC address. It is printed as a QR code
on a white sticker on the front of the speaker. Simply scan the QR code
with a smartphone or tablet QR reader app, and it will give you the MAC
address for that speaker.
3. Discover your speaker’s IP address. When it boots, the speaker uses
DHCP by default to automatically obtain a suitable IP address on your
local area network (LAN). It also runs Simple Service Discovery Protocol
(SSDP) so you can discover it from Windows Explorer or any SSDP-
enabled application.
From a Windows PC on the same LAN, open “My Computer.” In the left-
hand pane, go to the “Network” view.
Right-click in the right-hand Network pane and select “Refresh.” This will
start a search for devices on the network. You may get a popup asking
if you want to allow your PC to search the network, in which case you
should click “yes” or “allow.”
If you are not using SSDP or cannot discover the speaker on your
network, you can:
consult your DHCP server’s logs to determine its IP address;
use a network discovery app (such as Fing on iOS and Android);
or
use Wireshark to observe the DHCP network traffic.

www.wahsega.com Page 10
4. Once the search is complete, the speaker will appear in the Network
view as “Wahsega Speaker (:XX:XX).” The last two octets of its MAC
address will be included in its name, so you can easily distinguish
multiple units. Double-click the speaker’s icon to open its Web interface.
5. Once you determine the speaker’s IP address, navigate to that IP
address in your Web browser (for example, http://123.456.78.9).
6. When you access the webpages, the speaker will ask for a username
and password. The default username and password are admin and
admin.
7. On the right side of the page is the Status bar. It shows the current SIP
account status (default status is unconfigured and unregistered) and
the speaker’s system information (current IP address, Ethernet MAC
address and system time).
8. To change the IP address settings, go to the Network page and modify
settings in the WAN section. To set the network for DHCP, click the
Dynamic IP radio button. For static IP addressing, click the Static IP radio
button and fill in the relevant IP address fields with values from your
network administrator.

www.wahsega.com Page 11
9. To change the SIP account settings, go to the Accounts page and modify
settings in the account. Most users will only need to set
Username/Number (the phone number or extension assigned to this
speaker) and Domain (the hostname or IP address of your SIP server).
You may also provide an Account Name, which is used only for logging
purposes, and a Display Name, which may be used by your SIP server
depending on its configuration.
If a password is required for your SIP server or proxy server, provide it
in the Password field. If your SIP server or proxy server requires an
authentication username that is different from the name entered in
Username/Number, enter it under the Advanced tab in the Auth
Username field.
10. After configuring the network and SIP settings for your speaker, use
the configuration settings described in the next sections to customize
the speaker, intercom, panic button and other functionality.

Configuration and Web Interface
The Web interface is a set of webpages used to configure the various
settings available on the speaker. It allows the speaker to be configured
from any computer or device with a Web browser on the same network
as the speaker.

www.wahsega.com Page 13
General Settings
The General page configures settings for Room Mode and Panic Button.

Account Settings

www.wahsega.com Page 15
The Accounts page configures settings for Multicast and SIP accounts
for the primary speaker (Room 1) and second room speaker (Room 2), if
applicable.
There are nine (9) priority levels in each room for Multicast and SIP
calls. Four of the multicast streams are considered “high priority” and
four are considered “low priority.” The SIP account for each room is
considered “medium priority,” and its configuration options can be
found in the middle of the list.
Room 1 Multicast
Account name –The name to use to identify this Multicast
account. It will only be shown on this page and in the system logs.
Multicast IP address –The multicast IP address this account
should listen on to receive RTP audio. Valid addresses range from
224.0.0.1 to 239.255.255.255.
Note: Some addresses, particularly in the 224.xx.xx.xx
range, are globally reserved and should not be used!
Consider using addresses in the 239.255.xx.xx range,
which are “Administratively Scoped Local Addresses.”
Port –The UDP port this account should listen on to receive RTP
audio. Valid ports range from 1to 65535. Setting this to 0 will use
the default RTP port, which is 5004.
Room 1 SIP
Account name –The name to use to identify this account. It will
only be shown on this page and in the system logs.
Display name –The name to report to the SIP server, which may
be shown to other callers (depending on the SIP server’s
configuration).
