Greetings I'm a noob with FS (and VoIP generally!!) and am really struggling with getting 2 way comms between a PABX and a soft-phone using FS and an SPA8800. Calls from the PABX are OK, the FXO ports have registered with FS and when I dial the FXO extension I get the dial tone, dial the number for the soft-phone and it all works fine. The problem is connections *TO* the PABX. The SPA8800 AFAIK has a separate SIP port for each of its FXO ports. My understanding of how it should work is as follows: I have to have 4 gateways defined in a file in the sip-profiles/externals directory, each with a different "sip-port" line. I'm testing with 2 to start with: # cat cicsco_fxo.xml <include> <gateway name="fxoline3"> <param name="username" value="none"/> <param name="password" value="none"/> <param name="realm" value="172.27.1.20"/> <param name="sip-port" value="5260"/> <param name="register" value="false"/> </gateway> <gateway name="fxoline4"> <param name="username" value="none"/> <param name="password" value="none"/> <param name="realm" value="172.27.1.20"/> <param name="sip-port" value="5360"/> <param name="register" value="false"/> </gateway> I have to use mod_distributor to select one of the gateways that define the SIP ports. Thats is configured in the autoload_configs directory. # cat distributor.conf.xml <configuration name="distributor.conf" description="Distributor Configuration"> <lists> <list name="cisco_fxo" total-weight="2"> <node name="fxoline3" weight="1"/> <node name="fxoline4" weight="1"/> </list> </lists> </configuration> Finally, I use a dialplan to access this distribution of gateways when a 4 digit number starting with 8 is dialed from the soft-phone. # cat 33_ciscofox.xml <include> <extension name="pabx"> <condition field="destination_number" expression="^(8\d{3})$"> <action application="bridge" data="sofia/gateway/${distributor(cisco_fxo)}/$1"/> </condition> </extension> </include> Result expected - it all works. Result I get is: freeswitch@PBX.localdomain> 2012-06-29 04:13:44.287982 [NOTICE] switch_channel.c:926 New Channel sofia/internal/1002@172.16.164.33 [d0fc47e6-c1a0-11e1-881d-f70f560259d2] 2012-06-29 04:13:44.287982 [INFO] mod_dialplan_xml.c:485 Processing 1002 <1002>->8569 in context default 2012-06-29 04:13:44.298584 [ERR] mod_sofia.c:4492 Invalid Gateway '' 2012-06-29 04:13:44.298584 [NOTICE] mod_sofia.c:4889 Close Channel N/A [CS_NEW] 2012-06-29 04:13:44.298584 [NOTICE] switch_ivr_originate.c:2535 Cannot create outgoing channel of type [sofia] cause: [INVALID_GATEWAY] 2012-06-29 04:13:44.298584 [INFO] mod_dptools.c:2956 Originate Failed.
