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 !!!
by Anita Hall 27 Feb '12

27 Feb '12

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

Sangoma + Atcom Card on the same machine
by Anita Hall 27 Feb '12

27 Feb '12

Hi I am trying to configure Sangoma A104d + Atcom Card (4-port E1) on the same machine. Is it even possible using FreeTDM ? $lspci 01:06.0 Network controller: Sangoma Technologies Corp. A104d QUAD T1/E1 AFT card 01:07.0 Bridge: PLX Technology, Inc. Device 4002 (rev 01) For Sangoma card, I want to use the more stable libsng_isdn from Sangoma, while for Atcom card I will have to use libpri. Or may be, I should use libpri for both ? regards, Anita

How to avoid hearing fake ringback tone after bridging?
by dma 27 Feb '12

27 Feb '12

Hi All, The caller is able to hear the real outbound media, including ringback tone, network IVR/announcement, and etc. if the lua code is: session:answer() freeswitch.bridge(session, session2) However, the caller can only hear only fake ringback tone when "session:answer()" is removed. The SIP trace shows "SESSION PROGRESS" is received from the outbound channel. The setting of the call is: bypass_media = true bypass_media_after_bridge = true instant_ringback=false ignore_early_media=false Is there a solution that allow the caller to hear the real outbound media before the call is answered? Thanks, D.Ma -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/How-to-avoid-hearing-fake-rin… Sent from the freeswitch-users mailing list archive at Nabble.com.

IVR Architecture
by Anita Hall 26 Feb '12

26 Feb '12

Hi We are considering writing our own module for processing IVR in C. We are considering using mod_event_socket and then modify it to consume and produce the events internally instead of passing them to the socket. Is this a good idea? I know FreeSWITCH already has a mod_dialplan_xml which can use mod_curl to communicate to the outside world for I/O and DB access. But ... 1) Does XML have all the power flexibility that will be needed for powerful IVR applications? 2) Does mod_dialplan_xml use a separate thread for each IVR execution ? What will be the overhead of interpreting the XML ? 3) Any more ideas ? Thanks :) regards, Anita

Woomera
by Cliff Wells 26 Feb '12

26 Feb '12

I've been trying to discover a way to use woomera from FreeSWITCH. The information is sketchy at best. Currently we have a setup like the following: sangoma_mgd <-> woomera <-> asterisk <-> sip <-> FreeSWITCH I'd like to remove Asterisk from the equation, since basically all it does is act as a bridge (and consumes additional resources). I've tried mod_woomera that is available from the Project DiaStar, but it only worked partially (it seems to only support connecting to a single woomera server, and we will have many). I have also read in old (circa 2008) emails that mod_opal would one day lead to a new mod_woomera or perhaps support woomera directly, but haven't found much additional information. Is there any existing solution that I can apply to this problem? Regards, Cliff
