Problem with TLS connection
by Silvije Kalabić 28 Feb '12

28 Feb '12

Hello, Can somebody tell me if they have FS setup working using TLS connection only? We have some problems and they are very similar as described in this issue: * FS-3877: Reuse TCP connection for both directions * (http://jira.freeswitch.org/browse/FS-3877) How complex is root of this problem and is it something somebody else could solve if they had some time on their side and help from you?

Attended Transfer
by Виталий Давудов 28 Feb '12

28 Feb '12

Hello! I'm new to FreeSwitch. I try to implement the feature att_xfer in my dialplan. In default dialplan I found this line: <action application="bind_meta_app" data="4 b s execute_extension::att_xfer XML features"/> i.e. by pressing * 4, I can transfer this call to another extension. The question is: how do I replace the "* 4" to "flash" when performing this function? Thanks in advance. -- Best regards, Vitaly Davudov "VIP-TELECOM-SERVICE" Ltd.

Unregistering Phones When FS Is Manually Shut Down
by Jerry Richards 27 Feb '12

27 Feb '12

I noticed that FS does not send REGISTER expires 0 messages to registered endpoints when the Freeswitch process is shutdown for occasional maintenance. However, I did notice it sends SUBSCRIBE expires 0 to all presence subscribers. Is there a flag to cause it to send the REGISTER expires 0 in this case? Best Regards, Jerry

Help with debugging stuck threads/channels
by [Redhosting] Egbert Groot 27 Feb '12

27 Feb '12

Hi All, I'm running a freeswitch server with moderate load (at least, in my opinion..). Everything runs fine and stable. There is however one issue I have: occasionally a channel/thread gots stuck (and keeps that way until a full restart). Doing a uuid_kill doesn't help, and a uuid_dump got locked itself as well. I managed to get a core dump from the running process, and I can see a couple of threads in a locked state: "#0 0x00007f3878764be4 in __lll_lock_wait () from /lib/libpthread.so.0" etc. This is where my experience ends. How should I proceed in finding the cause of these locks? I've read these kind of locks can happen when doing 'fancy' things with cdr processing etc. In my setup this doesn't seem te be the case, as this is a 'simple' gateway only using the default modules. (for the stack trace see http://pastebin.freeswitch.org/18526 version: commit 224f4c0f8aefcb969ecab7ff9d3a66dce92bd943 / Tue Jan 24 11:38:41 2012 -0600). regards, Egbert.

sip stack has incorrect time
by Dave Horton 27 Feb '12

In the log snippet below, it looks like the FS core has an accurate local time, where the sip stack is logging time incorrectly. Why is this? 6454358312832000172723(a)10.1.10.101 2012-02-27 12:41:18 436896 [NOTICE] switch_ivr_bridge.c:398 Channel [sofia/internal/anonymous(a)anonymous.invalid] has been answered recv 567 bytes from udp/[10.1.10.101]:5060 at 17:41:18.455920: ------------------------------------------------------------------------ ACK sip:5753610@10.1.10.1:5060;transport=udp SIP/2.0 Via: SIP/2.0/UDP 10.1.10.101;branch=z9hG4bKac670929105 Max-Forwards: 70 From: "anonymous" <sip:anonymous@anonymous.invalid>;tag=1c645436806 To: <sip:5753610@10.1.10.1>;tag=Q7FpFH5yycF0j Call-ID: 6454358312832000172723(a)10.1.10.101 CSeq: 1 ACK Contact: <sip:1044@10.1.10.101:5060> Supported: em,timer,replaces,path,resource-priority Allow: REGISTER,OPTIONS,INVITE,ACK,CANCEL,BYE,NOTIFY,PRACK,REFER,INFO,SUBSCRIBE,UPDATE User-Agent: Audiocodes-Sip-Gateway-Mediant 1000/v.5.80A.055.002 Content-Length: 0 ------------------------------------------------------------------------ -bash-3.2$ date Mon Feb 27 12:41:23 EST 2012

Request to test fs_cli batchmode and new logging/capture script.
by Mitch Capper 27 Feb '12

27 Feb '12

I have worked in a logging/debugging tool for users to use when they are trying to have their situation debugged or file a bug report. The script collects output from freeswitch (events, sip traces, console messages) etc and can pastebin them or put them in a file. It also can automatically obfuscate sensitive information in the log files to make people working on production systems or with live data to feel more comfortable with submitting their logs. I am trying to find people to do two things: 1) Run a patched version of fs_cli and make sure its as stable as ever, without the batchmode flag (-b) people should see no change, to do this if you can just from your freeswitch source dir: wget "http://jira.freeswitch.org/secure/attachment/15730/fs_cli_batchmode_v8.patch" patch -p1 < fs_cli_batchmode_v8.patch and then compile and use freeswitch as normal (if you prefer to have the mofied fs_cli moved to another location see below) to revert back at any time just run: git checkout libs/esl/fs_cli.c and all changes are reverted At this point just use fs_cli(if you can test with the -b mode, no autocomplete or colors but other than that should work like normal) as long as it doesn't have any issues please comment in http://jira.freeswitch.org/browse/FS-3188 that you found it stable 2) To test the fs_logger.pl script, this script does not require perl support to be compiled into freeswitch, any different perl modules to run, or any external dependencies on any platform other than fs_cli to be in the same directory as the script or in its normal location (/usr/local/freeswitch/bin/fs_cli or the respective windows location). It should work on all platforms including windows. For windows users without perl you can also try the compiled version of the logging script at http://mitchcapper.com/fs_logger.exe . NOTE THIS SCRIPT will only work if you have the batchmode patch applied to source. For windows users who do not want to recompile that version of fs_cli can be found at https://mitchcapper.com/fs_cli.exe (just put it in the same directory as the script). For linux users you can easily test in a separate environment by doing the following: FINAL_DIR=/root/fs_cli_test/ mkdir ${FINAL_DIR} wget "http://jira.freeswitch.org/secure/attachment/15730/fs_cli_batchmode_v8.patch" patch -p1 < fs_cli_batchmode_v8.patch cd libs/esl/ && make && cp ./fs_cli ${FINAL_DIR} && cd ${FINAL_DIR} wget "http://jira.freeswitch.org/secure/attachment/15935/fs_logger.pl" "http://jira.freeswitch.org/secure/attachment/15936/fs_logger.txt" chmod +x fs_logger.pl This will put the modified version of fs_cli in /root/fs_cli_test along with the fs_logger.pl script and its readme in the same folder. If you wish to just download the script/readme they are located at: http://jira.freeswitch.org/secure/attachment/15935/fs_logger.pl http://jira.freeswitch.org/secure/attachment/15936/fs_logger.txt or in freeswitch-contrib/mitchcapper/fs_logger.* . fs_logger.txt has some details on usage, along with just running fs_logger.pl without args will show the usage information. fs_logger takes all args that fs_cli takes along with a few of its own. To do a sample run you can do: "./fs_logger.pl -oa -A" that will do the autos (input and output shown to simulate fs_cli, obfuscate the log output and pastebin the result). if you do not want it pastebined just do "./fs_logger.pl -oa -f test.log -ia -do" the ia and do are most useful to test as they are most likely to fail (they make fs_logger.pl interactive to more closely imitate fs_cli) The ticket for fs_logger.pl is http://jira.freeswitch.org/browse/FS-3945 If you run into issues or have any feedback with either please reply here and will be happy to help, thanks for testing and hopefully this will allow for some easier remote debugging down the line. As for why this uses fs_cli over the perl ESL its simply to make it as easy as possible for users and not require compiling/installing the ESL perl module and ensuring proper setup. As long as you have fs_cli then you can use fs_logger.pl. Thanks! ~Mitch

Imagine playing a 44.1 kHz mp3 file !!!

Yesterday, I saw someone storing his audio prompt files in 44.1 kHz mp3 for playback !!! I am still recovering from the shock! What will be the correct format to keep prompts in if we are connected via FreeTDM to an E1: GSM or PCMA? regards, Anita

how to identify caller based on CIDR for billing
by Muhammad Naseer Bhatti 27 Feb '12

27 Feb '12

Hello, In order to allow ACL authentication, ACL is defined for FreeSWITCH and IP address is entered in CIDR format. A /32 will have only 1 IP and /24 will have 254 IP address range. Now, FS will allow the call if the IP address falls under the subnet. For example, caller IP address is 192.168.10.24 while the ACL node is defined as 192.168.10.0/24. This works fine, but when it come to identify the incoming call for billing purpose, how can we identify the IP address matches to which customer? Or which ACL node for FreeSWITCH. One possible solution is to expand the CIDR used by FS, and then match the caller IP address, but I guess this will take too much resources. Am I missing something here? Or restrict the user to enter only 1 IP address per account? Thanks, Goni
