Call to registered phone behind NAT
by Oleg Khovayko 24 May '10

Hi, Please help. My FreeSWITCH has some mobile clients (Sipdroid and Nokia), keeps registration on the FS. See registration record samples: Call-ID: 571195090210(a)14.144.242.244 User: 1019(a)192.168.1.5 Contact: "user" <sip:1019@14.144.242.244:38592;transport=udp> Agent: Sipdroid/1.4.6 beta/T-Mobile G1 Status: Registered(UDP)(unknown) EXP(2010-05-19 16:38:41) Host: olegh.ath.cx IP: 208.54.35.47 Port: 30727 Auth-User: 1019 Auth-Realm: olegh.ath.cx MWI-Account: 1019(a)192.168.1.5 Call-ID: 30IpTq1FoIfJnxJC5ROP1HByEOig2n User: 1015(a)192.168.1.5 Contact: "user" <sip:1015@10.0.0.135;transport=TCP;fs_nat=yes;fs_path=sip%3A1015%4094.71.98.45%3A17476%3Btransport%3DTCP> Agent: Nokia RA-6 210.34.75 Status: Registered(TCP-NAT)(unknown) EXP(2010-05-19 15:57:27) Host: olegh.ath.cx IP: 94.71.98.45 Port: 17476 Auth-User: 1015 Auth-Realm: olegh.ath.cx MWI-Account: 1015(a)192.168.1.5 As you can see, for last samle (nokia) "Contact" contains line: sip:1015@10.0.0.135. In the real life, this phone NATed, and real IP (gateway's) is 94.71.98.45. Call from that phone is OK. But, when I try to call that phone from local, FS try to use wrong IP for connect: 2010-05-19 14:28:24.156706 [NOTICE] switch_channel.c:669 New Channel sofia/internal/sip:1015@10.0.0.135 [62b74c4f-7463-df11-ac63-005004c3cb7e] Of course, connection can not be established. Question: How to fix this problem? Or maybe, need to change FS, and always use REAL IP:PORT for establish outgoing call?

Implement Javascript setGlobalVariable() optional third parameter
by David Swardstrom 24 May '10

24 May '10

I am developing FreeSwitch Javascript capability to emulate some functionality that is currently provided by a Dialogic based proprietary system running on Microsoft Windows, originally using ISDN interfaces and then ported to Sip based VoIP capability. This system uses external post-processing code that processes "event" type data for billing and other purposes and I need to provide equivalent event data. As part of this effort, I need a counter that is guarantied unique when there is a possibility that multiple calls may access the counter. The proprietary code, this unique counter is provided by using InterlockedIncrement(). Looking at the available JavaScript code, it appears that using getGlobalVariable() and setGlobalVariable() as described in the SetGlobalVar Wiki page would allow me to do this as long as I was willing to allow holes in the count. However, I decided to look at the code to see exactly what was being done to implement this. I found was that there was no code at all to implement the 3rd optional parameter. I would like to implement this capability but extend the capability to truly provide a unique counter. To accomplish this, support must be provided by the switch core. I would like to provide a new routine into switch_core.c: <Following is the text for switch_core.h> /*! \brief Conditionally add a global variable to the core \param varname the name of the variable \param value the value of the variable \param val2 the value of the variable to verify against \ If the global did not exist and val2=="", add global with value, return true \ If the global exists with the value of val2, replace it, return true \ If the global exists with a value other than val2, return false */ SWITCH_DECLARE(switch_bool_t) switch_core_set_var_conditional(_In_z_ const char *varname, _In_opt_z_ const char *value, _In_opt_z_ const char *val2); Then the code in mod_spidermonkey.c can be modified to use this new switch core capability. Note: I have implemented this in my local version and have tested it.

Problem in uuid_broadcast and uuid_displace
by Sathish Babu 21 May '10

21 May '10

Hi Brian West, I received one incoming and put an fifo (in queue) and playing music continuously using the below code. (Caller A) @con.execute("fifo", "callforce_fifo_#{@sa_park_num} out wait undef '#{music}'") In the another channel i am receiving the incoming call (Caller B) and i have bridged that call with the customer number (Caller C) using the below code. @con.execute("bridge", "sofia/gateway/junctionnetworks/#{@callout_number}") . Now Caller B and C are connected and i am transferring the Caller C to Caller A using the uuid_transfer and disconnecting the caller B @con.sendRecv("api uuid_transfer #{@gcallin_uuid} -bleg callforce_fifo_#{@gsa_id} XML public") After executing the above code Caller A and Caller C is connected and Caller B is disconnected. Caller A and Call C both can speak each other. But i need to play the message message to both Caller A and Caller C also i have the uuid of Caller A and Caller B. In order to play the message to the both the caller i tried using the uuid_broadcast and uuid_displace but the message is not played to any one of the caller. Also i could not found any error in the free switch log file. Help me to solve this issue. Tried using the Caller A UUID: @con.execute("uuid_broadcast", "#{Caller_A_UUID} playback::/opt/freeswitch/sounds/wel_lf1.wav bleg") - Not Working @con.execute("uuid_broadcast", "#{Caller_A_UUID} playback::/opt/freeswitch/sounds/wel_lf1.wav aleg") - Not Working @con.execute("uuid_broadcast", "#{Caller_A_UUID} playback::/opt/freeswitch/sounds/wel_lf1.wav both") - Not Working @con.execute("uuid_displace", "#{Caller_A_UUID} start /opt/freeswitch/sounds/wel_lf1.wav") - Not Working Tried using the Caller B UUID: @con.execute("uuid_broadcast", "#{Caller_C_UUID} playback::/opt/freeswitch/sounds/wel_lf1.wav bleg") - Not Working @con.execute("uuid_broadcast", "#{Caller_C_UUID} playback::/opt/freeswitch/sounds/wel_lf1.wav aleg") - Not Working @con.execute("uuid_broadcast", "#{Caller_C_UUID} playback::/opt/freeswitch/sounds/wel_lf1.wav both") - Not Working @con.execute("uuid_displace", "#{Caller_C_UUID} start /opt/freeswitch/sounds/wel_lf1.wav") - Not Working I need urgent help from any one to fix this issue. How to identify where is the problem? Thanks in advance Thanks and Regards, Sathishbabu

Hi Brian West* *, Thanks for your kind reply. But i could not able to get the uuid of the bridged call i am using the below code but Other-Leg-Unique-ID returns empty. @con.execute("uuid_dump", "#{@uuid}") #Where @uuid is the uuid of the inbound call transfer_info = @con.getInfo(); transfer_uuid = transfer_info.getHeader("unique-id") other_leg_uuid = transfer_info.getHeader("Other-Leg-Unique-ID") @logger.debug "The transfer uuid is #{transfer_uuid} and other leg uuid is #{other_leg_uuid}" while executing the above code other_leg_uuid is empty. Please help me to solve this issue. Thanks and Regards, Sathishbabu

Re: [Freeswitch-dev] switch_odbc.c connect "max_tries" variable
by Vitalii Colosov 20 May '10

20 May '10

Hi, I am using core ODBC for MySQL connect. Trying to implement failover using 2 servers - main and backup. If main server is not responding, it should try to query backup server. The following is used in my module: if (switch_odbc_handle_callback_exec(*globals.master_odbc*, sql, my_func_callback, &pdata, NULL) != SWITCH_ODBC_SUCCESS) { switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_ERROR, "(***)Error running query on master database: [%s]\n", sql); switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_INFO, "(***)Trying backup database: [%s]\n", globals.backup_odbc); if (switch_odbc_handle_callback_exec(*globals.backup_odbc*, sql, my_func_callback, &pdata, NULL) != SWITCH_ODBC_SUCCESS) { switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_CRIT, "(***)Error running query on master and backup database: [%s]\n", sql); } } ... Right now it tries to reconnect to main server 120 times before it gives up and goes to backup server. I found the following in the switch_odbc.c: int max_tries = 120; Is there is a way to disable this check, so if it will not be able to connect to master, it will immediate go to backup server? I know I can change the source, but this will be already "customized core" - don't want to go in this direction. Or maybe there is a better way to handle database fail over in my module? Thank you, Vitalie

Play message to the bridged calls
by Sathish Babu 20 May '10

20 May '10

Hi I received one inbound call after processing the call i put that call in the fifo queue using the below code in the ruby script. @con.execute("fifo", "callforce_fifo_#{@sa_park_num} out wait undef '#{music}'"). So this caller is hearing the music continuously. After that i am (freeswitch) receiving one call from asterisk after answer that call i am bridging this call with the some other outside number using the below code. @con.execute("bridge", "sofia/gateway/junctionnetworks/#{@callout_number}") Now i am patching the outside number with the incoming call which i received early using the uuid_transfer function as shown below. con.sendRecv("api uuid_transfer #{callin_uuid} -bleg callforce_fifo_#{sa_id} XML public") Patching is happening properly. both the parties can hear the voice. Now after patch the both caller, i need to play the voice file(same) to both the caller. How to achieve this? Thanks and Regards, Sathishbabu

by Sathish Babu 20 May '10

20 May '10

Hi, I have received one inbound call and i am patching that call with some outside number using the below code in ruby script. @con.execute("bridge", "sofia/gateway/junctionnetworks/#{@callout_number}") Both the call is getting connected and they can able to communicate each other. But how can i get the uuid and other call details of the dialed call (using the bridge). Also if i execute the uuid_transfer(as below) is the freeswitch is generating any new uuid that? con.sendRecv("api uuid_transfer #{callin_uuid} -bleg callforce_fifo_#{sa_id} XML public") Thanks and Regards, Sathishbabu
