Hi all, Trying to build ruby and lua extensions from freeswitch/libs/esl: lua]$ make g++ -Wno-unused-function -c esl_wrap.cpp -o esl_wrap.o esl_wrap.cpp:1510:17: fatal error: esl.h: No such file or directory compilation terminated. make: *** [esl_wrap.o] Error 1 this can be fixed adding -I../src/include to esl_wrap.o task but has ld error then: lua]$ make g++ -Wno-unused-function -I../src/include -c esl_wrap.cpp -o esl_wrap.o g++ esl_wrap.o -llua -lpthread -o ESL.so -L. /usr/lib/gcc/i686-pc-linux-gnu/4.7.0/../../../crt1.o: In function `_start': (.text+0x18): undefined reference to `main' esl_wrap.o: In function `_wrap_new_ESLevent__SWIG_0': esl_wrap.cpp:(.text+0x3974): undefined reference to `ESLevent::ESLevent(char const*, char const*)' esl_wrap.o: In function `_wrap_new_ESLevent__SWIG_1': ... (tl;dr) Same with ruby (even worse), it was failing to find ruby.h and ruby/config.h. I got make esl_wrap.cpp task fixed http://pastebin.com/uKFBZVF3 but there's an ld error again: $ make g++ esl_wrap.o -lpthread -lrt -ldl -lcrypt -lm -L. -rdynamic -Wl,-export-dynamic -o ESL.so -L. /usr/lib/gcc/i686-pc-linux-gnu/4.7.0/../../../crt1.o: In function `_start': (.text+0x18): undefined reference to `main' esl_wrap.o: In function `rb_class_of': esl_wrap.cpp:(.text+0x9ed): undefined reference to `rb_cFixnum' esl_wrap.cpp:(.text+0x9fa): undefined reference to `rb_cTrueClass' Anyone successful with this stuff? I'm not experienced with GCC stuff at all. It would be very nice to pack this Ruby ESL to a gem (ruby package manager). BR, Phil

Terminal Emulators
by Michael Collins 06 Apr '12

06 Apr '12

Hey folks, Today on the conference call we had a brief but passionate discussion about terminal emulators. I'm finding that more and more I'm using all of the "big 3" operating systems and that they each have their own quirks and peculiarities. I decided to start a wiki page on the topic: http://wiki.freeswitch.org/wiki/Terminal_emulators I have been spending more time than I really want to on a Windows laptop so I have been getting familiar with putty. I added some putty info to the wiki plus a few other tidbits. I would like to invite everyone to hop on and add whatever knowledge or tips & tricks that they've learned over the years. If you know of a good terminal program that you use then feel free to add it to the list. Thanks! -MC

Requirements to get actual UUIDs?
by Michael Giagnocavo 06 Apr '12

06 Apr '12

Hello, Does anyone know what's required for APR to generate UUIDs? Currently, FreeSWTICH is generating sequential timestamp-like numbers instead of UUIDs. When configuring APR, I get this output: Checking for OS UUID Support... checking uuid.h usability... yes checking uuid.h presence... yes checking for uuid.h... yes checking for library containing uuid_create... no checking for library containing uuid_generate... -luuid checking for uuid_create... no checking for uuid_generate... yes checking for os uuid usability... no This is on CentOS 6.2. Installed packages: libuuid, libuuid-devel, e2fsprogs, e2fsprogs-devel, and util-linux-ng. What do I need to do to make APR pick up on this and generate proper UUIDs (that is, 128 bits of randomness)? -Michael

mod_esf ignores client BYE
by Lesley Pervis 04 Apr '12

04 Apr '12

I've discovered a bug with multicast paging that affects phones (like Cisco/Linksys/Sipura) that listen for multicast session control packets to hang up. Sniffing on the FreeSWITCH shows that FreeSWITCH does not respond to caller BYE on hangup, but waits five minutes before timing out waiting for media. It then sends its own BYE and sends multicast session control packets. For those five minutes, mod_efs is stuck continuing in a for(;;) loop and phones that count on hearing the multicast session control packets stay in session. The problem is with FreeSWITCH not replying to client BYE. I don't think the problem is necessarily in mod_esf, but currently this is beyond my ability to troubleshoot further. If anyone has an intuition on how to proceed, please let me know. I've raised a bug report in JIRA and it's been auto-assigned, but I haven't seen an indication it's been acknowledged. The bug is here: http://jira.freeswitch.org/browse/FS-4067 I've attached pcap and logs to the bug report.

ZRTP Code Now In Tree
by Michael Collins 02 Apr '12

02 Apr '12

Hello all! This isn't an announcement so much as an FYI. Phil Zimmermann has been working diligently with our very own power user Travis Cross (IRC: tc) on getting ZRTP into a truly useful state. The first big step on that journey has been taken: libzrtp code has been added to the git repository. Travis Cross reports that getting to this point was a serious amount of work, and for that we thank him and Phil both. We are all going to benefit from ZRTP when it is ready for use. The code is available for your perusal, however it is not quite ready for use at this time. We invite everyone to join us on the FreeSWITCH conference call this Wednesday (agenda here<http://wiki.freeswitch.org/wiki/FS_weekly_2012_04_04>). Travis will be discussing what has been done thus far and what remains to be done. This will dovetail nicely with AEP who will be discussing the Freedom Fone project on Wednesday also. -Michael

lua problems
by adam harris 02 Apr '12

02 Apr '12

I want to receive dtmf events I have problems with the following code. con = freeswitch.EventConsumer("all") session:setVariable("playback_terminators", "0123456789") session:execute("playback", "/usr/local/freeswitch/sounds/SAMPLE.wav") while (session:ready()) do for e in (function() return con:pop(1) end) do event_name = e:getHeader("Event-Name") or "" if(event_name == "DTMF") then print("have DTMF") print(e:getHeader("DTMF-Digit")) end end end I thought con:pop should work like on esl_recv_event however in this case after the first incoming dtmf it freezes? It does not respond on further key presses. On some instances the console has printed two entries when I am sure I only press the key once. have DTMF 8 have DTMF 8 I saw a posting online about the adding optional timeout parameter to pop. Has this been offically implemented because I get an error when using it like con:pop(1, 6000) 2012-04-02 13:42:50.643708 [ERR] mod_lua.cpp:191 Error in pop expected 1..2 args, got 3 stack traceback: [C]: in function 'pop' /usr/local/freeswitch/scripts/aprompt.lua:11: in function '(for generator)' /usr/local/freeswitch/scripts/aprompt.lua:11: in main chunk I have not found esl_recv_event_timed function in lua. If it does not exit in lua what is correct the equivilent way? On a further note is Session.collectInput going to be available in lua?

SIP Presence Activities
by Anthony Novatsis 02 Apr '12

02 Apr '12

Dear All, I am having some unexpected behaviour with SIP presence and would like some clarification. I have a FS server setup to manage sip presence (manage-presence=true in the SIP profile) and have two clients connected. The clients online/offline status is reported correctly however when a client publishes an activity of "away" the other client only receives status "open" without the associated activity. Here is the XML that I have observed on the wire (IP addresses replaced): PUBLISH (sent by client) <?xml version="1.0" encoding="UTF-8"?> <presence xmlns="urn:ietf:params:xml:ns:pidf" xmlns:es="urn:ietf:params:xml:ns:pidf:status:rpid-status" entity="sip:3011@a.b.c.d"> <tuple id="sg89ae"> <status> <basic>open</basic> <es:activities> <es:activity>away</es:activity> </es:activities> </status> <contact priority="0.8">sip:3011@a.b.c.d</contact> <note>away</note> </tuple> </presence> NOTIFY (sent by FS) <?xml version="1.0" encoding="ISO-8859-1"?> <presence xmlns='urn:ietf:params:xml:ns:pidf' xmlns:dm='urn:ietf:params:xml:ns:pidf:data-model' xmlns:rpid='urn:ietf:params:xml:ns:pidf:rpid' xmlns:c='urn:ietf:params:xml:ns:pidf:cipid' entity='sip:3011@a.b.c.d'> <tuple id='t6a5ed77e'> <status> <basic>open</basic> </status> </tuple> <dm:person id='p06360c4a'> <dm:note>Available</dm:note> </dm:person> </presence> I observe the same behaviour when a client sends other activities such as dnd, busy, etc. I thought that FS would just forward the published status/activity to the subscribers. Is there a way to configure FS to behave in this way? Thank you very much in advance. Anthony
