Hello, working one: http://pastebin.com/ncyxUQj8 nonworking one with 503 service unavailable http://pastebin.com/w7A689Bu Here i have two scenarios, first is configured with Provider(1), this call routed and established successfully. the second is configured with Provider(2), with this one freeswitch sending 503 event before routing the call to Provider(2) so why 503? - Devang.

Incoming call timeout
by Lợi Đặng 09 Dec '16

09 Dec '16

Hi list, when the callee ignore the call, My FS automatically disconnect the call by responding to the caller leg `480 Temporarily Unavailable`, and compose CANCEL send to the callee, after exactly 60 seconds. Which parameter I could set in sip profile to disable that behavior, or possibly increase the timeout value. I'm sorry I was unable to find one. Many thanks. rgds, Loi Dang Thanh Phone : +84. 1224.735.448 Email : loi.dangthanh(a)gmail.com

Socket Error [Too many open files]
by Caio Assis 08 Dec '16

08 Dec '16

Good afternoon. Freeswitch info: Freeswitch version: Version 1.6.12 64bit O.S: Centos 7 Processor: Xeon Six Core RAM: 8GB Disk: SSD samsung 850 pro I've been facing a problem with freeswitch. When I generate many calls (around 300 calls), Freeswitch service stops receiving socket connection after this error: [ERR] mod_event_socket.c:3017 Error initilizing connection [CRIT] mod_event_socket.c:235 Stateful Listener 0 has expired [ERR] mod_event_socket.c:2975 Socket Error [Too many open files] I set the configuration below, but the problem persists and I have to restart the service to get it back up. ulimit -c unlimited # The maximum size of core files created. ulimit -d unlimited # The maximum size of a process's data segment. ulimit -f unlimited # The maximum size of files created by the shell (default option) ulimit -i unlimited # The maximum number of pending signals ulimit -n 999999 # The maximum number of open file descriptors. ulimit -q unlimited # The maximum POSIX message queue size ulimit -u unlimited # The maximum number of processes available to a single user. ulimit -v unlimited # The maximum amount of virtual memory available to the process. ulimit -x unlimited # ??? ulimit -s 240 # The maximum stack size ulimit -l unlimited # The maximum size that may be locked into memory. ulimit -a # All current limits are reported. I can't execute any freeswitch command, fs_cli -x "show calls", fs_cli -r, they all return that socket error. Thanks.

t38 fax receive stuck
by Mirko Brankovic 08 Dec '16

08 Dec '16

Hi, I have a strange situation where faxes gets stuck for good amount of time on rxfax application. Detailed debugging let me to conclusion that one side doesn't send signal back and the other side is not 'timing out'/ giving up. Callflow is fax...provider...gateway... rxfax(file.tif) Here is the log: > b8a0b22f-5733-499d-a32f-712106821a53 2016-12-07 10:08:03.434513 [DEBUG] > sofia.c:5677 Channel sofia/external/496421607583(a)89.184.172.62 entering > state [ready][200] > 2016-12-07 10:08:03.504510 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38T Type > FCD - CRC OK (clean) > 2016-12-07 10:08:03.504510 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 Stop > none (0 remaining) > 2016-12-07 10:08:03.504510 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 Rx: > FCD without final frame tag > 2016-12-07 10:08:03.504510 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 Rx: ff > 03 06 41 02 d1 a5 0b d2 bf ef ff af ae 77 1f 06 eb 88 5e bf fb 82 40 5f 7f > 15 04 41 af ba 2e d5 13 48 8c 5f d7 9f 20 13 87 62 6c ba e8 e2 4b 5c 89 40 > ec ea 1b 32 c7 21 e2 29 08 7a 41 10 f4 d6 fd ff aa bf ff 1f 22 2e 30 1e 82 > e2 5f 02 81 56 e9 ab 6e 08 02 bd 21 5c c3 82 20 90 ff 08 d6 fa 5f 10 e1 b8 > 59 55 10 84 e8 e2 0e fd 55 a6 70 28 34 8e 7f 7f c7 02 4b 47 15 04 fd 0c e9 > ff 4d c9 53 1b 7d d5 af ff f5 bf 52 0e 02 f9 70 54 ad a3 7f bd 4a 70 cc 2d > 15 5d c4 67 08 59 69 fc 5f fa 15 ba f5 82 a0 c8 91 bd 25 fd 11 b5 be 5e 53 > 69 3a 2e ad ea 8f a8 af 12 04 fd ff 43 d0 10 e8 fd 54 8b 21 ba d8 fa ff 9a > 2f 53 89 24 04 21 9a 64 31 3f 52 69 e2 13 9f 2e ba e8 d2 ff 7f 21 04 aa 82 > 88 ff 35 7d ba 40 a0 5d 5f 7a bc 9e 10 fd 2f be 52 5b fa ef a8 a6 e2 ff ff > 6b f5 fd bf d0 d1 ff 7a ff > 2016-12-07 10:08:03.504510 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 Storing > ECM frame 65, length 256 > 2016-12-07 10:08:03.524532 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 Receive > complete in phase T30_PHASE_C_NON_ECM_RX, state 7 > 2016-12-07 10:08:03.524532 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 Non-ECM > signal status is Carrier down (-1) in state 7 > 2016-12-07 10:08:03.524532 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 > Trainability (TCF) test result - 14512 total bits. longest run of zeros was > 14480 > 2016-12-07 10:08:03.524532 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 > Changing from phase T30_PHASE_C_NON_ECM_RX to T30_PHASE_B_TX > 2016-12-07 10:08:03.524532 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38T Set rx > type 0 > 2016-12-07 10:08:03.524532 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38T Set tx > type 4 > 2016-12-07 10:08:03.524532 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 > Changing from state 7 to 8 > 2016-12-07 10:08:03.524532 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 Tx: > CFR with final frame tag > 2016-12-07 10:08:03.524532 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 Tx: ff > 13 84 > 2016-12-07 10:08:03.524532 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 No > signal is present What I think from the log is that there is no signal from the initiating side, which leads to the message "No signal is present" but my question is why would spandsp still keep waiting? Problem is that this is quite old version of FreeSwitch (FreeSWITCH Version 1.2.0 (git-89c590c 2012-05-08 20-08-26 +0000)) based on ooooold commit 89c590c I've looked at the git diff between the current spandsp and that one, and there are some changes but not that much. Can anyone familiar with this bring some light to me please :) Thanks, -- Regards, Mirko

how should I use "recording_follow_transfer=false"
by Babak Yakhchali 08 Dec '16

08 Dec '16

Hi I'm using a simple extension to bridge and record calls to local extensions: <extension name="simple_bridge"> <condition field="destination_number" expression="(....)$"> <action application="set" data="recording_follow_transfer=false"/> <action application="export" data="RECORD_STEREO=false"/> <action application="set" data="current_record_path=$${base_dir}/recordings/archive/${strftime(%Y-%m-%d-%H-%M-%S)}_${destination_number}_${caller_id_number}.wav"/> <action application="record_session" data="${current_record_path}"/> <action application="bridge" data="user/$1"/> </condition> </extension> I need the recording to stop after each transfer, but after transfer, recording will not stop and there will be two recorded files and the first one records the second call too!

communication between verto and outbound proxy
by Jamie McClelland 08 Dec '16

08 Dec '16

Hi all, I have written an outbound event socket that is executed every time a user joins a conference call. It executes special commands when the user presses certain digits. I've also written a verto-based web client that connects users to the conference via the outbound proxy so users can connect via the web or connect via phone. I'm looking for a way the outbound event socket can communicate directly with the verto web participants and vice-versa (e.g. a way it could subscribe to the verto conference chat channel). Right now, the verto web clients can communicate to the outbound event socket by sending dtmf keys. And, I've managed to get the outbound event socket to communicate to the verto clients using the "chat 'verto|from|to|message'" command. However, these methods are limited so I'm looking for alternatives. Thanks in advance for any help you can provide. jamie -- May First/People Link Growing networks to build a just world http://www.mayfirst.org https://support.mayfirst.org OpenPGP Key: http://current.workingdirectory.net/pages/identity/ xmpp: jamie(a)mayfirst.org

How can I cancel a bgapi job?
by D D 07 Dec '16

07 Dec '16

Hi, How can I cancel a bgapi job? Let's suppose I do bgapi command to originate a call and then am immediately told it needs tobe cancelled...but it has not started yet. Even if I supply my own uuid on the originateand a job-uud on the bgapi command, I don't see any way I can cancel the "unstarted" call. Note that I can construct a test case for this situation by doing a fs_cli command bgapi originate {originate_delay_start=30000,origination_uuid=my_uuid}sofia/gateway/...This command will start a request that cannot be cancelled until the call actually starts (thirtyseconds later). Any ideas? Thanks,David

mod hiredis throwing response error[(null)][4] on getting value
by Aqs Younas 07 Dec '16

07 Dec '16

Greetings list, I am testing mod_hiredis to store some values in cache. I see whenever I try to get a value against a key which does not exist. I see errors in logs freeswitch@debian> hiredis_raw default get key2 2016-12-07 10:19:09.033417 [INFO] hiredis_profile.c:86 hiredis: recycled from pool[localhost, 6379] Unknown Command: hiredis_raw default get key2 2016-12-07 10:19:09.033417 [ERR] hiredis_profile.c:222 hiredis: response error[(null)][4] 2016-12-07 10:19:09.033417 [ERR] mod_hiredis.c:107 hiredis: profile[default] error executing [get key2] reason:[] whereas in the case of Memcache, this thing is handled well enough. freeswitch@debian> memcache get key2 -ERR NOT FOUND I have two questions here, 1) Is it possible to make hiredis to throw errors more sufficiently? Like returning null instead of throwing these errors. 2) Is hgetall available in hiredis? Best, Aqs Younas

Segfault when running tone2wav

Hello list, I was testing tone2wav and it basically just segfaulted. I put the following line into file itu.tone: v=-7;%(100,0,941.0,1477.0);v=-7;>=2;+=.1;%(1400,0,350,440) Then I ran: # tone2wav itu.wav itu.tone File: itu.wav generated...

Freeswitch and mobile clients
by Gregor Nanger 07 Dec '16

07 Dec '16

I would really appreciate feedback. I am using Zoiper (Android) as mobile client and it constantly loosing connection with freeswitch after a while. It show registration timeout. I set transportation to TCP to preserve battery drain and set to keep awake in background. Is there something I can set in FS like session timeout that would help. Can you please point me how to debug. Which mobile client you are using?
