Linksys and Sipura Phones (SPA Phones)

Prerequisites

Linksys allows public download of documentation and software on their website.

• Phone network configuration completed.

  The following instructions assume your phone has successfully booted and completed network configuration including obtaining valid IP addresses for itself, an IP gateway and DNS servers either via DCHP, manual or other means (refer to your phone's documentation) and that your phone is running with factory defaults.

• Phone is running firmware release 5.1.15 or better.

  You can find the firmware version your phone is currently running by using the Menu button (looks like a dog-eared piece of paper) on your phone and navigating to Product Info -> Software Version. If you are running a version prior to 5.1.15, please upgrade your phone's software before proceeding (refer to your phone's documentation).

Step 1: Gather information for each user.

Each user has a set of credentials which will be needed to configure each phone. For each phone that you are configuring, obtain the following:

• SIP Address (Address of Record)
• SIP Password
• Auth Username
• Username
• Proxy/Domain

You can find this information in the user detail pages under the Users tab in the Phone Configuration section.

Step 2: Log into your Linksys/Sipura phone through a web browser

1. You will need the IP address of the Linksys/Sipura device. Touch the Menu key on the phone and choose 9 for Network. You will see the CurrentIP of the phone displayed. (For an analog adaptor, via a touch tone telephone attached to the PHONE port, press the start key four times (****) to enter the Sipura Configuration Menu. Enter 110# to hear the IP address.) Take note of the IP address. You will need it later.
2. Run a web browser application on the same network as the Linksys device. Type the following into the browser address bar to access the web-based configuration portal:
   http://(linksys ip address) /admin/advanced where the (sipura ip address) is the IP address you obtained in Step 4 above.
3. Now select the EXT 1 tab at the top of the page.

Step 3. Enter your user information from Step 1.

Make the following changes:

Under the "General" heading:

• Line Enable = yes

Under the "NAT Settings" heading:

• NAT Mapping Enable = no
• NAT Keep Alive Enable = yes

Under the heading "Call Feature Settings"

• Blind Attn-Xfer Enable: yes

Under the "Proxy and Registration" heading:

• Proxy: = Domain (from Step 1 above)
• Outbound Proxy: = sip.onsip.com
• Use Outbound Proxy: = Yes
• Use OB Proxy In Dialog: = Yes
• Register: = Yes
• Register Expires: 600

Under the "Subscriber Information" heading:

• Display name = (whatever you like)
• User id = Username (from Step 1 above)
• Password = SIP Password (from Step 1 above)
• Use Auth ID = yes
• Auth ID = Auth Username (from Step 1 above)

Click "Submit All Changes" Button and wait for Sipura device to reboot.

Lastly - RTP Packet Size:
Once the phone reboots from above, choose the "SIP" tab.

• Scroll down to the "RTP Parameters" Section.
• Find the field called: "RTP Packet Size:"
• By default it is set to 0.030
• Change it to 0.020

Scroll to the bottom and choose "Submit all Changes"

Step 4. Confirm that your phone is registered.

In the User portal, click on the "Users" tab. You will see a green "online" notation next to each user with a registered phone.
