Atcom MP01 and Elastix Server Setup Guide http://www.elastix.org
1.0 Setup Diagram This is a setup diagram for a mesh network of Atcom MP01 configuration. When everything is configured we ll be able to call between analog phones and also to have communication with Elastix sever. Figure 1-1. Setup Diagram 2.0 Host PC Environment Table 2-1.

4.0 Setup Procedure To prepare Elastix for incoming calls and outgoing calls to the mesh network follow these steps: 1. Go to the web address of the Elastix Server Login page. The web address is determined by the customer, for this guide we have used the IP address 192.168.1.75 2. On the Login page, type the username and password for an administrative user into the Username and Password fields see Figure 4-1. The username and password are determined by the customer. Figure 4-1. Login 3. Let s create an Elastix SIP extension for communication with analog phones of the mesh network. For this go to PBX => PBX Configuration => Extension. Click on Submit having selected Add SIP Device option. (Figure 4-2) Figure 4-2. SIP Extension 4. Fill in the following information on the Add SIP Extension page (Figure 4-3): 3
User Extension (302 in this example) Display Name ( IPPhone in this example) secret ( h7dka3rf9si0t in this example) Figure 4-3. Add SIP Extension 5. Click on Submit button and Apply changes by clicking on the pink ribbon that appears at the top of the page. Configure the IP Phone with the same extension and password. 6. Now we ll create a SIP trunk to register only one MP01 in order to have communication between MP01 s network and Elastix sever. Go to PBX => PBX Configuration => Trunks. Click on Add SIP Trunk, then Submit (Figure 4-4). Set the following parameters: General Settings Trunk Name: A name for the SIP trunk ( MP01Trunk in this example) Outgoing Settings Trunk Name: mesh PEER Details: type=friend context=default disallow=all qualify=yes dtmfmode=rfc2833 canreinvite=no host=192.168.1.99 (MP01 s IP address) allow=gsm,ulaw (This configuration have been taken from a recommendation of VillageTelco who is the promoting organization of Mesh Potato project.) 4
Figure 4-4. Trunks 7. Click on Submit Changes and apply changes. 8. If the MP01 is behind a NAT firewall, you have to edit the file /etc/asterisk/sip_general_custom.conf and add the following line: nat=yes 9. For outgoing calls from Elastix to the mesh network we need to specify a prefix that will allow making calls using the SIP trunk. To do this, go to PBX => PBX Configuration => Outbound Routes. Click on Add Route link (Figure 4-5). Set the following: Route Settings Route Name: ( 9_Mesh in this example) Dial patterns Prefix: ( 9 in this example) Match pattern: (. in this example) Trunk Sequence for Matched Routes 0: The trunk that we just created ( MP01Trunk in this example) Figure 4-5. Outbound Route 5
10. Click on Submit Changes and Apply configuration. The configuration in Elastix is ready. If we want to call an extension on Mesh Potato we have to dial 9 and then the number but before we have to configure the MP01. 6
Configuring Atcom MP01 Only one MP01 must be configured with a SIP Trunk to register with Elastix. For the other ones you only need to follow steps 8 and 9 to configure the extension number for the analog phones connected to them. 1. Connect a PC directly to one MP01 device using a straight network cable. 2. Enter to the MP01 web interface by pointing your browser to the MP01 s IP address. Factory default settings IP Address 192.168.1.20 Web Access User Name root Web Access Password (none) 3. Login into the WebUI using the credentials by default specified in the table above (Figure 4-6) Figure 4-6. Login 4. Once inside, change the administrator password to have SSH access later. Go to the top-right menu and choose the LuCI option (Figure 4-7) Figure 4-7. 5. From the top menu, go to System => Admin Password, and set the new password for the MP01 device (Figure 4-8). 7
Figure 4-8. Changing password 6. Change the IP address according to your network. From the top menu go to Network => Interfaces => LAN (Figure 4-9) Figure 4-9. LAN settings 7. Disconnect the cable from MP01 and connect it to the network. You should be able to access to MP01 through the new IP address and using the new password. 8. Once logged in, set the following parameters to configure the mesh network (Figure 4-10): Network IP Address: This is the wireless IP address of the MP01. The last number of this address will be the extension of the analog phone connected to this MP01. 8
Figure 4-10. In this example the extension would be 20 because that is the last number of IP address. Configure each MP01 in the same network but different extension. 9. If you changed the IP address, click on the refresh button located next to Network to save changes. Reboot the device by disconnecting the power cord and connecting again. 10. Now we have to register the Mesh Potato device using the parameters we set for the SIP Trunk in Elastix. To do this login using SSH access to the MP01 with the password we set before (Figure 4-11). Figure 4-11 11. Edit the file /etc/asterisk/sip.conf. Add the following line at the end of the section [general] (Figure 4-12): register = mesh@mesh/mesh Then add these lines at the end of the file: [mesh] type=friend context=default disallow=all qualify=yes 9
dtmfmode=rfc2833 canreinvite=no host=192.168.1.75 (IP of Elastix Server) allow=gsm,ulaw,alaw nat=yes Figure 4-12 12. Save the file and go to Asterisk CLI to reload the SIP service by typing sip reload. Then check out if the SIP trunk is registered with Elastix. You should see the trunk registered, something like this: Figure 4-13 13. Now you should be able to call from the IPPhone using the prefix 9 to a number of the Mesh Potato. 14. If we want to call from the analog phones to Elastix and reach the IP Phone we have to configure the dial plan in MP01. Edit the file etc/asterisk/extensions.conf. Add the following line at the beginning of the section [default] (Figure 4-14). exten => _1XXX,1,Macro(page,SIP/${EXTEN}) Figure 4-14 This line means that if we want to call an extension in Elastix server we have to dial 1 followed by an extension of 3 digits (In this guide it would be 1302 to call to the IP Phone). You can set more or less digits. For any number of digits you can set _1X. 10
15. Save the file and go to Asterisk CLI to reload the dial plan service by typing dialplan reload. If you have configured all the MP01 with a valid extension you will be able to make calls between analog phones and also to Elastix through SIP trunk. 11
Calling directly without using a trunk prefix If you want to call directly the number of the analog phone extension without the prefix of the trunk, follow these steps: 1. Go to to Elastix WebUI and create a virtual extension with the same number of the analog phone extension. Go to PBX => PBX Configuration => Extensions and select None (virtual exten) (Figure 4-15) Figure 4-15 2. Fill out the following information. Add extension User Extension: 20 (Analog phone extension) Display Name: 20 Voicemail & Directory Status: Enabled Voicemail Password: 1647 Figure 4-16 3. Click on Submit button and Apply Changes. Now click on the extension we just created to edit the Follow me feature (Figure 4-17). Figure 4-17 12
4. On the section Add Follow Me Settings, set the Follow Me List and the Destination if no answer (Figure 4-18): Edit Follow Me Follow-Me List: 920# Destination if no answer Voicemail : <20> 20 (unavail) Figure 4-18 5. Click on Submit Changes and apply changes. Now we can call to an analog phone by dialing just the extension 20 instead of 920. It will automatically use the SIP trunk to communicate to Mesh Potato. 13
