Is this some kind of xml-generating script for register bindings (as in here: http://wiki.freeswitch.org/wiki/Mod_lua/Serving_Configuration)? If that's the case, you have no session object, and you will have to follow the information on that wiki page instead. /Peter Från: freeswitch-users-bounces(a)lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] För Samira Mh Skickat: den 3 juli 2012 12:16 Till: FreeSWITCH Users Help Ämne: Re: [Freeswitch-users] how to get the content of sip header ? for example i want to read the value of sip-header ' CSeq' in lua(that is configure for mod_xml in /usr/loca/freeswitch/conf/autoload/lia.xml.conf), must to issue as follow: local var = session:getVariable("sip_CSeq") but the error occure: attempt to index global 'session' (a nil value) REGISTER sip:192.168.10.89 SIP/2.0 Via: SIP/2.0/UDP 192.168.18.120:33648;branch=z9hG4bK-d8754z-7e634b5c7a239f6b-1---d8754z-;rport Max-Forwards: 70 Contact: <sip:1000@192.168.18.120:33648;rinstance=313a890c6a269acd> To: <sip:1000@192.168.10.89> From: <sip:1000@192.168.10.89>;tag=695adb0d Call-ID: MGUzNTFkZWVlOTcwODBmOWViNGY4MjM3MzE2NTQzMTM.

Inbound EventSocket anomoly
by Ben Langfeld 03 Jul '12

03 Jul '12

Gents, I was hoping someone would be able to clear up what appears to be an obvious omission from IES. If I execute the playback application on a channel via IES, I get an immediate response to indicate it was queued, and I then have to wait for either PLAYBACK_STOP or CHANNEL_EXECUTE_COMPLETE. The problem is, the response contains nothing to filter events by. The only link I have are the 'Application' and 'Application-Data' fields on the event, and there is no guarantee those are unique to an individual application execution. I would expect the immediate response to return a UUID which would be present on the related events. Am I missing something, or is this actually a bug? Example: https://gist.github.com/40f079ae2a079abe6393 Regards, Ben Langfeld

I'm not sure if that specific header i available, but that is not the problem here.

How to add profiler flag when making just one module
by Tom C 03 Jul '12

03 Jul '12

I'd like to build one module (mod_fifo) with the -pg compiler flag. But my inexperience with gcc makefiles is making it difficult. :-) Does anyone have any info for doing profiling in a FreeSwitch module? The only way I can get it to even compile with the profiling flag is to run ./configure to set the flag for ALL modules, then make mod_fifo, then re-run configure to remove the flag. My code: $> export MOD_CFLAGS="-pg" $> export CFLAGS="-pg" $> ./configure $> make mod_fifo $> # undo the changes so I don't screw up my entire build. $> export MOD_CFLAGS= $> export CFLAGS= $> ../configure Unfortunately, ./configure takes about 40 minutes to run on my poor little pogoplug, and then "make mod_fifo" feels the need to rebuild a bunch of libraries with the -pg flag (which I don't want), which adds another 15 minutes. In all, my script takes 105 minutes to run. After all this, I can see the -pg flag in use when doing "make mod_fifo", and -pg shows up in the relink_command in mod_fifo.la. But it doesn't create the profiling data file, so apparently the -pg didn't actually work. I'm stumped. :-)

Playback of multiple wavs in a round-robin scenario
by BookBag 02 Jul '12

02 Jul '12

Hello all, I have been searching day and night for a way on how to do this. I have a customer who would like like random ads stored as wav's to be played once an incoming call comes in. For example, this customer has 5 ads each one in its own wav file. If an incoming call comes in, one of those wav's gets played. When a second call comes in, another wav gets selected and gets played. Anybody can help point me in the right direction. Thank you.

FreeSWITCH Weekly News and Notes
by Michael Collins 02 Jul '12

02 Jul '12

Welcome to July! We hope the leap second didn't crash any of your servers. Some folks were not so fortunate<http://www.bbc.co.uk/news/technology-18672173> . On last week's conference call we had an open discussion on topics chosen by members of the community. One topic that got a fair amount of traction was how to address NAT when FreeSWITCH has a public IP address and the clients themselves are behind NAT. Dave Kompel shared his strategy of using "aggressive-nat-detection" on the SIP profile and then optionally setting "NDLB-connectile-dysfunction" for the directory entry. We also discussed other topics like IPv6 and using FreeSWITCH in the cloud with Amazon. The audio is available here<http://torrents.freeswitch.org/conf_call_2012-06-27.torrent?cc12-0702> . Darren Schreiber's company, 2600hz, made a very interesting announcement<http://www.prnewswire.com/news-releases/2600hz-launches-new-service-kazoo-b…>regarding "Kazoo BETA." This new cloud-based PBX solution uses a lot of open source software under the hood, including FreeSWITCH. Stay tuned for a more in-depth discussion with Darren about this new platform. On the ClueCon front we are happy to report that many have taken advantage of the fact that they can get 2^4 tickets (i.e. 16 tickets) for the drawings at ClueCon 2012. The bits will shift at the end of the day tomorrow, July 3, so don't delay! You can register quickly and easily here<http://www.cluecon.com/register?cc12-0702>on the ClueCon site. After July 3rd registrants will receive 2^3 or 8 tickets. Don't delay - we are giving away a total of ten 7" Android tablets among many other prizes supplied by our sponsors<http://www.cluecon.com/sponsors?cc12-0702> . Only 35 days until ClueCon 2012! -- Michael S Collins ClueCon Team http://www.cluecon.com 877-7-4ACLUE cc12-0702

(false detected and) generated dtmf when bridging calls using uuid_bridge on any leg wich uses start_dtmf
by Michael Lutz 02 Jul '12

02 Jul '12

Hi, Trying again... I have a serious issue with randomly generated dtmf's on bridged calls on where i have a provider wich does not support rfc2833 and I have to use start_dtmf in the dialplan to make dtmf's work. My setup is: A> 1 incomming call, using start_dtmf to activate inband dtmf detection. This makes dtmf work correctly in my (Lua) IVR scripts and respond to digits. (not all the time, but that might be a different issue?) B> This call is at some point in IVR bridged directly from the Lua script to new call on the same switch (no start_dtmf). This script activates a Lua scrpt from the dialplan which does some plays. (so caller A can hear this- as they are bridged) (there is no 'start_dtmf' on this incomming call in the dialplan) C> The Lua script B then triggers a an inbound ESL connection which is generating a completely new session using an api call "originate ... &park()" When C answers the phone, C is bridged to B using api call "uuid_bridge C B" after that B is instructed to end the Lua script to make the bridge work (the bridge works only after the Lua scripts ended) from my ESL connection I have two listeners, one on A and one on C to listen for (dtmf) events. So, there are two bridges, A<->B and B<->C, becuase B is a new incomming session this al works perfectly, and I can do asynchronous stuff from my ESL server and I do need to leave my orignial Lua script A (which is required) The problem: When the incomming call A is using inband detection (start_dtmf in the dialplan) I get a lot (almost always) spontaneous generated dtmf events on the A legg. I am 1000% sure they are not pressed. My ESL listener on A detects them and is showing them in my log. It mostly 'detects' generaly unused dtmfs like 'A' and 'D'. but sometimes also just 'normal' digits. (like '7' in my pastebin) The behaviour leads to hearable dtmf's to C, which of course find it very anoying to hear beeps. They are not heard on the A leg. I can easily reproduce same behaviour on an rfc2833 incomming call and forcing the C leg on inband detection using an "execute_on_answer=start_dtmf" in my originate call. Which is the same setup as my case, but just switched the leggs. Th exact same behaviour will occur but only the dtmf's are detected/generated on the C leg (called user) instead of the A leg (calling user). I have added switchlogs on pastebin: http://pastebin.com/WwW3eDgK for this particulair situation. Please ANY help would be appreciated! I was thinking using for example 'stop_generate_dtmf', to at least make FS stop generating RTP dtmf when (falsely) detecting them. But that doesn't solve the root cause of course, and I have no idea what the consequence might be as that function is not very well documented... Thanks for any help, Regards, Mike.
