Yea I have been meaning to get around to it. I'll put it on my todo and see if I can figure it out. Sorry for the inconvenience.

Manipulate the SDP origin field
by Chris Graham 25 Oct '11

25 Oct '11

Hi All, I have an issue whereby my cluster is in a mixed nat and not-nat environment. I would like to manipulate the o= field on a per call basis. In short I would like to achieve the below two scenarios, based on the dialplan Internal offer: Owner/Creator, Session Id (o): root 4267 4267 IN IP4 192.168.1.1 External offer: Owner/Creator, Session Id (o): root 4267 4267 IN IP4 208.73.210.48 I have tried the below, with no success to the origin field. dialplan.xml <action application="bridge" data="{sip_from_uri=sip:${caller_id_number}@208.73.210.48}${lcr_auto_route}"/> vars.xml <X-PRE-PROCESS cmd="set" data="bind_server_ip=208.73.210.48"/> internal.xml <param name="ext-rtp-ip" value="$${local_ip_v4}"/> <param name="ext-sip-ip" value="$${local_ip_v4}"/> external.xml <param name="ext-rtp-ip" value="208.73.210.48"/> <param name="ext-sip-ip" value="208.73.210.48"/> Thanks in advance for any assistance, Chris G

Are the parameters defined in the XML config files visible to Lua scrips? In this case it is the script for loading up the directory. Hynek

ESL on Ruby 1.9.2
by Claudio Álvarez 25 Oct '11

25 Oct '11

Hi everyone, I've been able to compile the ESL wrapper for Ruby 1.9.2, however, I'm getting an abnormal behavior with a small script (100% functional with Ruby 1.8.7) which basically opens an ESL socket connection and listens to channel events: The event loop looks like the following: con = ESL::ESLconnection.new('localhost', '8021', 'ClueCon') con.events('plain', 'CHANNEL_ANSWER CHANNEL_HANGUP_COMPLETE CHANNEL_BRIDGE CHANNEL_EXECUTE_COMPLETE') i = 0 EM.run do while (con.connected) e = con.recvEvent() EM.defer do if (!e.nil? && !e.getHeader("variable_medularis_uuid").nil? && !e.getHeader("variable_clicktocall").nil?) on_event(e, con, i) i = i + 1 end end end The problem I'm experiencing is that the event loop seems to be reading events from the socket out of sync. For example, when I answer a call, nothing happens (i.e. no event is processed), however, when I hangup, the CHANNEL_ANSWER event is read from the socket. As you can see, I'm using EventMachine, however, I've also tried Ruby threads and I'm getting the same behavior. Any clues on this issue? Has anyone tried Ruby 1.9.2 successfully with ESL? Thanks!

DTMF Problems
by Antonio Teixeira 25 Oct '11

25 Oct '11

Hello. This questions is not specific to FS but to all the SIP Gateways. We currently work with several Voice Providers , including the big carriers BT , etc and this situation happens from time to time and some more frequently then other. We call phone A , the person answers and presses some keys and voila RTP Events Received , all goes well. We disconnect and call that exact phone and DTMF is not working anymore ,... We disconnect the call from another provider and we have again the DTMF Tones. Now we try another carrier and the same situation happens . Do anyone of you guys have anything to say on this a best practice , should i use RFC2833 and in band at the same time trying to catch any missing tones ? Regards Antonio Teixeira

SDP rewriting
by srg 25 Oct '11

25 Oct '11

i am trying to rewrite the video codec in the SDP header from a SIP client A. It works only partially. Client A sends invite with the SDP header to FS trying to call client B and FS changes the video codes due to: <action application="set" data="switch_r_sdp=$1m=video 9078 RTP/AVP 102
a=rtpmap:102 H264/90000
a=fmtp:102 profile-level-id=42C014
"/> in my dialplan/default.xml file. I know that this first change by FS works correctly because i can see the SDP header via wireshark. Client B then answers with 200 ok and a SDP header but FS then does not send the SDP header from client B to client A but a mixture of the original SDP header from client A and the SDP header from B's answer. >From added logging to the FS code i see that the SDP header which is given to nua_respond(..) in mod_sofia.c when FS sends the 200 okay to client A is still as expected. So from where comes the mixed SDP header ? Am i missing some more settings in the dialplan/default.xml file ? -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/SDP-rewriting-tp6928152p69281… Sent from the freeswitch-users mailing list archive at Nabble.com.

Re: [Freeswitch-users] Task was executed late - warning messages
by Peter Olsson 25 Oct '11

25 Oct '11

Only one recommendation - don't do it :) At least not for a production system. The problem is usually the lack of accurate timers - and this exactly what you're experiencing here.. If you want to continue to run it virtually, there are a few basic things to check; first make sure you never share more cores to the virtual machines than you have in your physical hardware. Also use a separate NIC for the FS box. You must also make sure you don't have other overload issues, disk IO etc. This way you might be able to get it work "good enough", but in the long run nothing beats real hardware... /Peter ----- Reply message ----- Från: "Network Information Centre" <nic(a)itecity.com> Datum: tis, okt 25, 2011 02:41 Rubrik: [Freeswitch-users] Task was executed late - warning messages Till: "'FreeSWITCH Users Help'" <freeswitch-users(a)lists.freeswitch.org> Yes, Windows Hyper-V w/1 core and 1 GB Ram.

Advise on FS core dump

Hi Friends, i'm using mod_nibblebill for billing on FS, i bundled event processing fucntions when status change, e.g. /* on_routing */ check_billing_before_routing, and * on_hangup */ process_hangup, as below, however, i found if i make a call containing two-legs e.g. user 1001 call user 1002, then the FS core dump. but if i only make one leg call, e.g. call 888 for IVR, then no problem occure, i found the problem within function "check_billing_before_routing" (because once i comment all of lines within this func, the core did not dump). below is the func "check_billing_before_routing", can anyone help advise what's wrong? how should i correct it, thanks. static switch_status_t check_billing_before_routing(switch_core_session_t *session) { //charles, check billing before routing the call char buf[128]; char cmd[100] = "check_billing_before_answer"; FILE *pp = NULL; const char* in_username = NULL; const char* in_calledstation = NULL; const char* in_uniqueid = NULL; const char* in_network_addr = NULL; const char* in_type = "9"; int is_b; //const char* full_cmd; int i_continue = 1; switch_channel_t *channel = NULL; in_uniqueid = switch_core_session_get_uuid(session); channel = switch_core_session_get_channel(session); /*only billing on a leg*/ is_b = channel && switch_channel_get_originator_caller_profile(channel); printf("is_b is: %d\n", is_b); if(is_b) { return SWITCH_STATUS_SUCCESS; } /* Lock this session's data for this module while we tinker with it */ if (globals.mutex) { switch_mutex_lock(globals.mutex); } in_username = switch_channel_get_variable(channel, "caller_id_number"); in_calledstation = switch_channel_get_variable(channel, "destination_number"); in_network_addr = switch_channel_get_variable(channel, "network_addr"); /* Done checking - release lock */ if (globals.mutex) { switch_mutex_unlock(globals.mutex); } switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_INFO, "check_billing_before_routing, in_username: %s, in_calledstation: %s, in_uniqueid: %s in_type: %s, in_network_addr: %s \n", in_username, in_calledstation, in_uniqueid, in_type, in_network_addr); strcat(cmd, " "); strcat(cmd, in_username); strcat(cmd, " "); strcat(cmd, in_calledstation); strcat(cmd, " "); strcat(cmd, in_uniqueid); strcat(cmd, " "); strcat(cmd, in_type); strcat(cmd, " "); strcat(cmd, in_network_addr); printf("excute external cmd: "); printf(cmd); printf("\n"); if( (pp = popen(cmd, "r")) == NULL ) { printf("popen() error!\n"); exit(1); } while(fgets(buf, sizeof buf, pp)) { printf("the result of excuting external cmd: %s", buf); } if(pp) { pclose(pp); } i_continue = atoi(buf); printf("i_continue: %d", i_continue); if (!i_continue) { switch_log_printf(SWITCH_CHANNEL_SESSION_LOG(session), SWITCH_LOG_INFO, "call was not authorized to continue \n"); transfer_call(session, globals.nobal_action); } return SWITCH_STATUS_SUCCESS; } Core dump logs: freeswitch@freeswitch> 2011-10-24 16:30:26.583369 [NOTICE] mod_xml_rpc.c:969 Starting HTTP Port 8787, DocRoot [/usr/local/freeswitch/htdocs] 2011-10-24 16:30:29.454743 [WARNING] sofia_reg.c:1337 SIP auth challenge (INVITE) on sofia profile 'internal' for [6628(a)224.193.106.204] from ip 223.128.70.10 2011-10-24 16:30:30.254710 [NOTICE] switch_channel.c:897 New Channel sofia/internal/8068(a)224.193.106.204 [196a50b8-eaa0-4ef0-a674-18602117f5ec] is_b is: 0 excute external cmd: check_billing_before_answer 8068 6628 196a50b8-eaa0-4ef0-a674-18602117f5ec 9 223.128.70.10 2011-10-24 16:30:30.254710 [INFO] mod_nibblebill.c:1017 check_billing_before_routing, in_username: 8068, in_calledstation: 6628, in_uniqueid: 196a50b8-eaa0-4ef0-a674-18602117f5ec in_type: 9, in_network_addr: 223.128.70.10 the result of excuting external cmd: the result of excuting external cmd: 60 Segmentation fault (core dumped) [root@freeswitch bin]# -- Regards, Charles
