Configuring the Device

• Step 1 - Initial setup.
  • Connect the SPA-3102 to your internal network (the one connected to the lmce subnet)
  • Proceed with initial configuration via the administration page. Once you set passwords and locale settings, you can move to the next step
  • Note, you can leave the dhcp and network settings as is. We will not be using the routing functions of this device. You will need to make a note on the address assigned to the device.

• Step 2 - SIP connection settings.
  • Click the PSTN Line settings.
  • Choose 'Admin' and 'Advanced' option in the top left right corner to see all available options.
    • Do not change anything other than what you need. There are a lot of options!
    • Line Option Set to enable.
    • Sip Settings
      • Make sure the port is set to 5061
    • Proxy and registration

Configuring FreePBX

  • Using the top navigations, goto Advanced -> Configuration -> Phones Setup.
    • This will take you to the freePBX panel. Take care to only change designated settings as you can mess things up.

  • This will show you the existing trunks (phone lines). Choose Add Trunk.
  • Then choose Add Sip Trunk.
  • Next are the options presented:
    • Outbound Caller ID : Caller ID for calls placed out on this trunk.
    • Maximum channels: Set this to '1'
    • Dial Rules : Still working on this part. Idealy, it would be used for local non toll calls as well as 911 or any other local services.
