Hanging Call- no CALL DESTROY events even when users ended the call

Hi, I am using mod_python script for IVR functionality, and facing an issue. Even after users end the call, no CALL DESTROY events are captured by the Freeswitch and after a while Freeswitch itself crashes with following logs: *7fd202913000-7fd202914000 rw-p 0000a000 08:02

Freeswitch Crashes on Call Hangup of IVR Session using mod_python script

mod_expr random not thread safe?
by Stanislav Sinyagin 16 Sep '17

16 Sep '17

I'm building a test for voice quality, and I need to randomize the silence preamble. At the same time, other sessions are recorded into a tmpfs file. <action application="set" data="rand_val=${expr(randomize(&x);ceil(random(0,100,&x)))}"/> I noticed that when I added this, the audio recordings started to have gaps of dropped audio 40ms long. Are the randomize() and random() thread-safe at all? It seems like the whole FreeSWITCH process freezes when one of those functions gets executed.

Hi guys, is it safe to call uuid_record multiple times for the *same uuid and path* ? Will it just ignore the subsequent calls and continue recording or will it clear the file and restart the recording?

Hangup_hook is not getting called in mod_python script
by Deepika Yadav 14 Sep '17

14 Sep '17

Hi, I have implemented a functionality where when a person with his mobile phone number calls a specific number (that of SIM inserted in our GOIP hardware), the incoming is hanged and that person is called back. After the IVR menu starts playing and if in between caller hangs up, hangup_event is not detected and the registered hangup_hook does not get called. Code is as follows; *XML file that starts python script when the person answers the cal*l: <extension name="record_topic"> <condition field="destination_number" expression="^4449"> <action application="set" data="execute_on_answer=python *python.sangoshthi_IVR_handler*"/> <action application="sleep" data="30000"/> </condition> </extension> *Python Script handler:* def handler(session, args): session.setHangupHook(hangup_hook) session.setInputCallback(input_callback) print('session object value is ', str(session)) callerid = session.getVariable('caller_id_number') call_uuid = session.getVariable('uuid') phone_number = callerid[len(callerid)-10:] initial_greeting(session, phone_number, call_uuid) def hangup_hook(session, what, args=''): """ Must be explicitly set up with session.setHangupHook(hangup_hook). `session` is a session object. `what` is "hangup" or "transfer". `args` is populated if you pass extra args to session.setInputCallback(). """ print('PERSON HANGED UPPPPP...........') freeswitch.consoleLog("INFO", "hangup hook for '%s'\n" % what) -- Regards, Deepika https://deepikay.wixsite.com/deepika

DTMF events not occurring while using VOIP-GSM gateway hardware locally
by Deepika Yadav 14 Sep '17

14 Sep '17

Hi I need to originate calls to Indian mobile numbers from my python ESL script. I used to use service from a company for sending calls from Freeswitch to GSM network for which I set up external SIP profile. But recently I bought my own GOIP hardware, though I am able to make calls but DTMF events are not getting captured on Freeswitch, API like playandGetDigits does not work and there are no logs on Freeswitch console. -- Regards, Deepika https://deepikay.wixsite.com/deepika
