3 4.0 Setup Procedure To set up the Elastix Server for the Khomp KGSM-USB SPX Interface Card: 1. First go to the Elastix Command Line Interface and install a khomp module for this card. You can use ssh connection or directly from the Elastix Server. Once there, type the following: yum install kernel-module-khomp service asterisk stop /etc/rc.d/init.d/khompdrv service kserver start service asterisk start Figure 4-1. Elastix CLI 2. To see the status of the Khomp KGSM Card enter to Asterisk CLI by typing asterisk r. Once there type khomp channels show (Figure 4-2). Figure 4-2. Asterisk CLI 3. We can see an active channel that is where we placed the SIMCARD in the Khomp KGSM-USB. Close Asterisk CLI by typing exit. 4. Now you need to edit a configuration file to make incoming calls use the PSTN context in Elastix (or any context). In the command line type vim /etc/asterisk/khomp.conf and find the line ;context-gsm-call. Press i key to 3

4 switch to the Vim Edition Mode and erase the semicolon and the current value and replace it by from-pstn (Figure 4-3). Figure 4-3. Editor VIM 5. Press ESC key and type :x followed by ENTER to save changes and exit the Vim Editor. You can close the file without saving changes with :q!. Reload asterisk by typing asterisk rx reload in Elastix CLI (Figure 4-4). Figure 4-4. Reload Asterisk 6. Now, we 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 On the Login page, type the username and password for an administrative user into the Username and Password fields, see Figure 4-5. The username and password are determined by the customer. Figure 4-5. Login 8. Press Enter or click on the Submit button to go to Elastix s Dashboard 9. Once inside, we will create a trunk for outbound calls. Click on the PBX tab on the menu at the top of the screen 4

5 Figure 4-6. PBX 10. Go to Extensions and select Generic SIP Device to create an extension for our IPPhone. In the Add SIP Extension page fill in the following information (Figure 4-7): Add Extension User Extension: (302 in this example) Display name: ( IPPhone in this example) Device Options Secret: ( h7dka3rf9si0t in this example) Figure 4-7. Add SIP Extension 11. Click on Submit located at the end of the page and apply changes. Now, click on Trunks on the left side and select Add Custom Trunk (Figure 4-8). 5

6 Figure 4-8. Trunks 12. On the Add Custom Trunk page, set the following (Figure 4-9). General Settings Trunk Name: ( KhompTrunk in this example) Outgoing Settings Custom Dial String: khomp/b0c0/$outnum$ Figure Click on Submit Changes button located at the end of the page. Go to PBX => PBX Configuration => Outbound Routes. Click on Add Route (Figure 4-10). Set the following: Route Settings Route Name: ( 9_Outside_Test 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 ( KhompTrunk in this example) 6

7 Figure Outbound Route 14. Now you can make outbound calls through the SIMCARD calling a telephone number with 9 as prefix. 15. We ll create an incoming route for the calls from any external number to our SIMCARD. We re going to use an IVR for incoming calls. Go to PBX => PBX Configuration => IVR. Click on Add IVR (Figure 4.11). Set the following: Name: Name of IVR (WelcomeIVR in this example) Announcement: Record which will be played for incoming calls. Options: o * - Phone book. o Extension o t - Repeat the options of IVR (Add this option by modifying the IVR after creation) Figure IVR 7

8 16. Click on Save and Apply changes by clicking on the pink ribbon that appears at the top of the page. Now go to PBX => PBX Configuration => Inbound Routes. Click on Add Incoming Route. (Figure 4.12). Set the following: Description: Name of inbound route ( Incoming_Calls in this example) Set destination: Where the call will be routed. ( WelcomeIVR IVR in this example) Figure Incoming Route 17. Click on Submit and apply changes. Now when we receive calls to the SIMCARD the IVR will play to the caller giving him choices to interact with Elastix Server. 18. Configure the IP (SIP) Phone with the correct parameters. 19. To test the configurations, pick up the previously configured IP (SIP) Phone and dial a mobile phone with 9 as prefix. When the call is established, speak into the phone and verify that the mobile phone can hear your voice. Next, from your mobile phone call to the SIMCARD number and when the call is established you should be interacting with the IVR. 8

9 SMS Configuration We can also set SMS functions for Khomp KGSM-USB. 1. For sending SMS from the SIMCARD, edit the /etc/asterisk/extensions_custom.conf (Figure 4-11). Inside the [from-internalcustom] context, add the line: include => sms-out sms-out is a name that can be defined by the user. Add the context: [sms-out] exten => 700,1,KSendSMS(b0c Testing SMS.) exten => 700,n,Hangup() 700: Extension we have to dial in order to send the message b0c0: The zeros in b0c0 represent the number of the board/card and the number of the channel/module where the SIM card you want to use is located respectively : The mobile phone number that will receive SMS Testing SMS: The message content you want to send. 2. When finish, reload asterisk by typing asterisk rx reload in the Elastix CLI. You can also use the Asterisk CLI to send a message. Use the following command: khomp sms b0c "Your message here" 3. Now, for receiving SMS to the SIMCARD from any mobile phone, edit the /etc/asterisk/extensions_custom.conf (Figure 4-13). Inside the [from-internalcustom] context, add the line: include => khomp-sms The first two zeros (00) define the board/card you want to create the context for. The second two zeros (00) will define which GSM Module (on the card) you want to create the context for. Since in this configuration only one card is used it is allocated the 00 position, and the SIMCARD is located in the first position (00). Add the context: [khomp-sms-00-00] exten => s,1,system(${ksmsfrom} ${KSmsBody}) 9

10 KSmsFrom and KSmsBody are variables available for processing of SMS, they contain the Sender and Content of the text message respectively. Figure When finish, restart asterisk service by typing service asterisk restart in the Elastix CLI. 5. To test the SMS sending, pick up your IPPhone and dial 700. After finish the call you will receive a message in the cell phone in the next seconds. To test the SMS receiving, enter to Asterisk CLI with the command asterisk -r in Elastix CLI, and send a message from any cell phone to the SIMCARD number. In the next seconds you will see something like figure Figure 4-14 NOTE: If at any time you want to remove or stop using a Khomp card, be sure to first edit the file: /etc/asterisk/modules.conf by adding the line: "noload => chan_khomp.so" in its [modules], otherwise the asterisk process will not be able to start properly. 10
