It is able to route calls between mobile phones. The described case assumes a freshly installed Asterisk with virgin configuration files. In the following we an interface for GSM Base Station, in this case, osmo-nitb. Now LCR will edit extensions.conf and sip.conf which can be found in the /etc/asterisk directory. The example below is not special connect to GSM, OpenBSC using its rather a normal SIP-trunk configuration. MNCC socket. Set up Add ‘bridge ast’ at the sip-trunk towards osmo-sip-connector: The first that has to be taken care bottom of is the connection to osmo-sip-connector. The following lines need GSM section. Now all calls from the GSM Base Station will be appended forwarded to sip.conf: Asterisk. cd /etc/asterisk/ ** Set up chan_lcr <pre> sudo gedit sip.conf [GSM] [ast] type=friend remote asterisk host=127.0.0.1 context from-lcr dtmfmode=rfc2833 earlyb no canreinvite=no tones yes disallow=all bridge GSM allow=gsm </pre> LCR will connect to Asterisk using chan_lcr using context name ‘from-lcr’. Calls from Asterisk will be context=gsmsubscriber port=5069 forwarded to OpenBSC. The connection is named GSM, this name phone numbers defined in hlr.sqlite3 will be used later to reference identify mobiles within the connection when routing outgoing calls. The context name “gsmsubscriber” references network. Please refer to the context where mobile originated calls are routed into example Asterisk configuration given below. ** Remove unnecessary interfaces Comment the dialplan. Set up a dialplan to route calls: last two interfaces named Ext and Int. We do not need these interfaces. Now you have Now Asterisk chan_lcr and osmo-sip-connector are connected. The following example introduces a very basic dialplan configuration GSM Base Station interface bridged to route each other. All calls between mobile phones. The following example can from one interface will be added redirected to extensions.conf: the other. No more routing configurations are necessary at this point. cd /etc/asterisk sudo gedit extensions.conf ** Set up permissions [gsmsubscriber] <pre> exten=>_XXXXX,1,Dial(SIP/GSM/${EXTEN}) nano options.conf exten=>_XXXXX,n,HangUp </pre> NOW HOW TO RUN : Uncomment the following 2 lines. LCR will not connect to chan_lcr if you do not set the user and group it runs on. ** open terminal run: <pre> osmo-nitb -c ~/osmo/openbsc.cfg -l ~/osmo/hlr.sqlite3 -P -C --debug=DRLL:DCC:DMM:DRR:DRSL:DNM -M /tmp/bsc_mncc open new terminal socketuser asterisk run: socketgroup asterisk osmo-bts-trx -c ~/osmo/osmo-bts.cfg open new terminal </pre> ** Configuring Asterisk Following is a simple example of asterisk dialplan that can be used to route all calls from OpenBSC back run: to OpenBSC. But a few extensions listed in the default dialplan are accessible. Add the following lines to osmo-sip-connector -c ./osmo/osmo-sip-connector.cfg open new terminal your @/etc/asterisk/extensions.conf@ <pre> run: [from-lcr] sudo asterisk -r open new terminal include => default run: exten => _X.,1,Dial(LCR/ast/${EXTEN:0},60) osmo-trx -c 1 -s 4 -e -l INFO </pre> open new terminal In this case, I am adding the default Asterisk dialplan. In Asterisk, default dialplan provides some features run: to test drive your network. You can call 1234 for information on Asterisk, and 600 for latency test. Please telnet localhost 4242 refer to the configuration file for more extensions. You might want to remove the default dialplan after enable you confirm that the network is working properly Now you running OpenBSC/BTS with Asterisk :-)
