Cisco SPA112 ATA Setup Guide

Setup Guide for Cisco SPA112 and SPA122 ATA Devices

Before you begin, ensure that you've created your extension in the My Account Portal, https://my.maxo.com.au/. To retrieve the details of an existing extension, or create a new extension, login to the My Account Portal and select SIP Trunks from the menu. If you're creating a new extension, click the Add Extension button, fill in the details and click Save. For additional information on creating an extension, please see Portal Guide - PBX Extensions and Sip Trunks

Find the extension number you're configuring, then click Edit.

Take note of the following fields, highlighted in the image below, as you'll need these to setup the device. 

• Register Username: This is the full username, not the short Ext No.
• SIP Proxy: The server you'll be connecting to.
• Re-Register Interval: Defines how often your device should check in.
• Password: The extension's password

Note that if the extension is already configured on a device, you'll need to reconfigure, power down or factory reset the currently connected device before the required information will be displayed.

As we will be configuring the device using its web interface, we need to retrieve the device's IP address.

Before you can retrieve the IP of the ATA, you will need to ensure the following is completed:

• A handset is connected to the Phone 1 port on the ATA
• The power is connected to the ATA, and the power icon is lit
• An ethernet cable is connected from your router to the ATA, and the Internet light is lit (temporarily connect your computer to the SPA122's LAN port to configure it)

To retrieve the IP, pick up the handset and (if required) open a line. Dial **** (four asterisks)

SPA112

At the voice prompt menu, enter 110 #. The phone will read back the IP address of the base, which can be entered into a browser to access the configuration.

SPA122

At the voice prompt menu, enter 210 #. The phone will read back the IP address of the base, which can be entered into a browser to access the configuration.

Once you have entered the IP address into your web browser, enter the username and password for the device. By default, these are both admin

Line Configuration

Select the Voice tab, then choose Line 1

Update the fields identified below, copying the Register Username, SIP Proxy and Password from the Configure Extension box as required:

Proxy: SIP Proxy (normally pbx.maxo.com.au or sip.maxo.com.au)

Register Expires: 120

User ID: Register Username

Dial Plan: (*xx.|000S0|0011x.|1[38]00xxxxxxS0|13[1-9]xxxS0|0[23478]xxxxxxxxS0|[2-9]xxxxxxxS0|xx.)

Regional Settings

To improve compatibility with analogue handsets, we recommend navigating to Regional, then setting the FXS Port Impedance to '220+820||115nF'

While not required, the following settings can help make your phone sound more Australian:

Dial tone: 400@-19,425@-19,450@-19;10(*/0/1+2+3)
Busy Tone: 425@-19;10(.375/.375/1)
Reorder Tone: 425@-19, 425@-29;60(.375/.375/1,.375/.375/2)
Ring Back Tone: 400@-19,425@-19,450@-19;*(.4/.2/1+2+3,.4/2/1+2+3)

Ring1 Cadence: 60(.4/.2,.4/2)

NBN Changes

If your connection is on the NBN, and you're experiencing issues receiving faxes, it may be necessary to change the NBN traffic class of your calls. There are two options for traffic classes below - if you're experiencing issues with one, please try the other.

To access this setting, navigate to Voice > Line 1. The fields are in the Network Settings section.

NBN TC1 - High priority, but limited bandwidth

SIP ToS/DiffServ Value: 0xb8

RTP ToS/DiffServ Value: 0xb8

NBN TC4 - Lower priority, with all available bandwidth

SIP ToS/DiffServ Value: 0x68

RTP ToS/DiffServ Value: 0x68

Once the above fields have been set, click Submit all Changes, and the ATA will reboot. Once it's rebooted, it will be online and ready for use.
