Setting up with linuxMCE

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.
  • Log in to the LinuxMCE web admin. Go to Wizard -> Devices -> Phones -> Add Device (bottom of the page). For device template select Generic SIP softphone. Rename the phone to something like SPA-3102 Line 1 and hit update. Note the extension of the phone. You will need it later.
  • If you want the phone attached to your SPA-3102 (Line 1) to ring when people call, you should go to Wizard -> Devices -> Phone Lines, and click Settings for the appropriate phone line(s). There you can modify the ringing behaviour of your new phone.

• 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.

      • For password I put the password for the extension (the extension number by default)
      • For 'Use Auth Id' I chose no.

Configuring FreePBX

• Step 1
  • Log into the webadmin.
  • 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.
  • On the left hand side, choose Trunks from the menu.
  • 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. Ideally, it would be used for local non toll calls as well as 911 or any other local services.

• • Outgoing Settings

 context: House Line

 allow=all
 context=DID_trunk_2
 dialformat=${EXTEN:1}
 hasexten=no
 hasiax=no
 hassip=yes
 port=5061
 registeriax=no
 registersip=no
 secret=12345678
 trunkname=Custom - telecom
 trunkstyle=customvoip
 username=pstn

• • Incoming Settings

 context: pstn

 allow=ulaw&alaw&g723.1&gsm
 context=from-pstn
 dialformat=${EXTEN:1}
 disallow=all
 hasexten=no
 hasiax=no
 hassip=yes
 host=dynamic
 port=5061
 registeriax=no
 registersip=no
 secret=210
 trunkname=Custom - telecom
 trunkstyle=customvoip
 type=friend
 username=pstn

Routing Calls

Currently, the call routing in this setup is incorrect. It will route into the linuxMCE telcom system, but it will not have the proper caller ID information. Im currently working on this. Please see update below

Setup update

I was able to get linuxMCE to treat the PSTN phone calls the same as ip calls. I can now get the caller ID (Partially in some cases) from the calls as they come in, and I no longer use the work around below.

To set this up properly, I did the following:

• Created an Inbound Route in the freePBX panel called 'House Line', the same user context as the incoming settings for my PSTN Trunk.
• Duplicated the settings similar to my Broadvoice settings, but there arent many. Whats critical is to make sure at the bottom, you send it to the custom app with this:

 custom-linuxmce,102,1

• Reload the panel and test it out.

Setting up a 'Ring All' Extension

*NOTE* this is a workaround i originally used in my attempts to figure this out. The setup above is the recommended path.

To bring the call in, i experimented with different methods and found some success here.

• Go to the freePBX main panel.
• On the left side, choose 'Ring Groups'
• On the top right side, choose Add Ring Group
  • Group Description : I put House Line.
  • Ring Strategy: Ring All
  • Extension List: Here I added an extension that didnt exist, so it would move on to the bottom.
  • You can experiment with the other settings, but for now we move onto Destination if no answer.
  • Choose the last option (Custom App) and enter this into the box:

 custom-linuxmce,102,1

• Save and apply changes.
• Test out the phone line.

Troubleshooting

This isn't a proper setup by any means, but it will be improved.

• • You can experiment with the different settings, but I recommend reading these links 1st.
