No early media or signaling to PSTN

Greetings I'm having some problems with getting sensible behavior when receiving calls through an external SIP->PTSN trunk. What we are experiencing: - Through ring_ready and sleep (the ringtone var is set prior), there is only silence. After the call is answered (dialplan answer), the following playback is delayed for about 10s. - When answering without ring_ready, the playback is also delayed ~10s - When using answer and playback ring-tone, everything is working, but leaves us in a sort of "dirty" state when directing the call further. It also means that we send a call directly to "unallocated", but need to playback ring tones beforehand. Can anyone provide me with some tips on how to debug this this issue further? Is it a firewall issue (everything is swell both in- and outbound), do I need to execute additional applications, or setup my gateway in a specific way? Best regards -- Kim Rostgaard Christensen | krc(a)retrospekt.dk | http://retrospekt.dk

thrubles whith DTMF
by Алексей Морозов 21 Dec '15

21 Dec '15

Hello. We have encountered a problem. We use bind_digit_action application to activate a number of features. To still have ability to pass DTMF signals between A_leg and B_leg, we use send_dtmf application. This is a part of our dialplan in the attached file. All work well but one snag - our customers from time to time complain inability to interact whith IVR. During debugging we have discovered that Freeswitch generates DTMF signals with volume = 13. The problem is that a lot of popular PBX and call managers (for example Cisco UCM) do not recognize DTMF with such low volume. Is it possible to set this value in freeswitch as we need or this parameter is not configurable? WBR Alex M

Dial plan variables
by Kyle Hunter 18 Dec '15

18 Dec '15

Hey, I’ve currently got a dial plan set up to receive faxes which looks like: <action application="rxfax" data="/var/spool/fax/FAX-${destination_number}-${caller_id_number}-${uuid}.tif"/> I’m just wondering what $destination_number variable is set to. In our SIP Header we’re sending a different ‘SIP Display info’ to what this variable is set to and I can’t seem to find what that variable is actually looking at.

core dump on playback after "Decode Codec is not initialized!" log message
by Adam Johnston 17 Dec '15

17 Dec '15

I was going to file a JIRA, but I'm not running on most recent commit of FreeSWITCH. I have not been able to reproduce this issue on-demand, but it has happened sporadically in both 1.4 and as of yesterday 1.7. A FreeSWITCH box will be running any number of calls (I've seen this happen with a handful and with hundreds) and will crash on WAV playback. The second-to-last message in the log file has been: [ERR] switch_core_codec.c:784 Decode Codec is not initialized! in every instance of this failure. Our use case is we originate calls via mod_event_socket and with an inline dialplan that starts spandsp_start_tone_detect (for beep detection) and then plays a playback string of silence followed by one or more WAVs (8-bit u-law). I have not been able to narrow the culprit down to one specific call. In the most recent crash all calls had negotiated to PCMU or PCMA. Any thoughts on how I could reproduce this so I can file a proper bug report? Some more info is below, and I'd be happy to provide any more information I can. info: * Amazon EC2 c4.xlarge instance * Debian 8.2 (jessie) * commit 2cb7188c1733a6524e5852f95bb71f12e0ffcc18 * FreeSWITCH version: 1.7.0+git~20151209T003048Z~2cb7188c17~64bit (git 2cb7188 2015-12-09 00:30:48Z 64bit) stack trace: #0 0x00007fe06a4a3750 in switch_core_session_read_frame (session=0x7fe0259a9078, frame=0x7fdfe0dd6090, flags=1641139939, stream_id=1762346489) at src/switch_core_io.c:501 #1 0x00007fe06a52934a in switch_ivr_play_file (session=0x7fe0259a9078, fh=0x7fdfe0dd6850, file=0x7fdfe0dd6810 "", args=0x7fe0690b45f9 <__lll_unlock_wake_private+25>, args@entry=0x7fdfe0dd6810) at src/switch_ivr_play_say.c:1721 #2 0x00007fe061362343 in playback_function (session=0x7fe0259a9078, data=<optimized out>) at mod_dptools.c:2810 #3 0x00007fe06a49e81a in switch_core_session_exec (session=0x7fe0259a9078, application_interface=0xba4340, arg=0x7fe0259a5170 "silence_stream://1000!718946f17f2b6e4638d510540952d58e.wav!silence_stream://5000") at src/switch_core_session.c:2783 #4 0x00007fe06a49edb8 in switch_core_session_execute_application_get_flags (session=0x0, app=0x7fe0259a5160 "playback", arg=0x7fe0259a5170 "silence_stream://1000!718946f17f2b6e4638d510540952d58e.wav!silence_stream://5000", flags=0x0) at src/switch_core_session.c:2653 #5 0x00007fe06a4a1d42 in switch_core_standard_on_execute (session=<optimized out>) at src/switch_core_state_machine.c:283 #6 switch_core_session_run (session=0x7fe0259a9078) at src/switch_core_state_machine.c:539 #7 0x00007fe06a49c0be in switch_core_session_thread (thread=<optimized out>, obj=0x7fe0259a9078) at src/switch_core_session.c:1629 #8 0x00007fe06a497e5d in switch_core_session_thread_pool_worker (thread=0x7fe0259cdd80, obj=0x0) at src/switch_core_session.c:1692 #9 0x00007fe06a579590 in dummy_worker (opaque=0x7fe0259cdd80) at threadproc/unix/thread.c:151 #10 0x00007fe0699ce0a4 in start_thread (arg=0x7fdfe0dd7700) at pthread_create.c:309 #11 0x00007fe0690a804d in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:111 Thank you, Adam Johnston

Solaris Performance
by Spencer Thomason 17 Dec '15

Hello all, I’m working on getting FreeSWITCH optimized and running well on Solaris. Can anyone using this platform or derivatives please test https://freeswitch.org/jira/browse/FS-8666 I saw a huge jump in performance on SPARC and I’m curious if this should be applied to X86 as well. Thanks!

Thread failure with low CPU utilization?
by Vladislav Ivanov 17 Dec '15

17 Dec '15

Hello, I have 1.6.5 Freeswitch and I'm trying to test how much lines/cps it can handle on my test machine: CPU: Intel(R) Xeon(R) CPU E5450 @ 3.00GHz x2 (8 cores, 3 GHz) RAM: 32GB SSD: 500 GB I'm using call generator to check flood the freeswitch, but when FS gets 1k sessions it sends [CRIT] switch_core_session.c:1781 Thread Failure! and the Star Wars quote... But the CPU load is less than 10% Ulimit is as follows: core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 128330 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 32768 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 2048 cpu time (seconds, -t) unlimited max user processes (-u) 32768 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited Server is physical, not virtual, but I dont have the same issue with virtual freeswitch.

hi, I put together the build scenario that I tested for ARM (armhf at scaleway.com) and it should also work for other architectures: https://freeswitch.org/confluence/display/FREESWITCH/Building+debs+for+othe… It will be great if someone tests them on other architectures too. cheers, stanislav

Someone have the same problem, or know the solution? ps. Reading the list, i realize that few members use the module, or don't have problems. If i am correct, is there any other way to use GSM modems or GSM, which is low cost? Is there anyone who can guide me in some things about the code or tips? ps 2. sorry about my english -- Luiz Fernando Softov http://www.softov.com.br fernando(a)softov.com.br
