Max Number of files sent to session.execute("playback", file)
by fgastiaz 12 Nov '08

Hi Guys, I have this problem when i'm trying to reproduce more than 8 prompts in a row. Here is code extract that simplifies the problem i'm having. If put something like this inside a script.py session.execute("playback","1.wav") session.execute("playback","2.wav") session.execute("playback","3.wav") session.execute("playback","4.wav") session.execute("playback","5.wav") session.execute("playback","6.wav") session.execute("playback","7.wav") session.execute("playback","8.wav") session.execute("playback","9.wav") The file 9.wav is not heard even though in the freeswitch.log it says that the file was sent to the module 2008-11-11 18:53:03 [DEBUG] switch_cpp.cpp:570 execute() CoreSession::execute. app: playback data:9.wav 2008-11-11 18:53:03 [DEBUG] switch_ivr_play_say.c:912 switch_ivr_play_file() Codec Activated L16@8000hz 1 channels 20ms 2008-11-11 18:53:03 [DEBUG] switch_core_session.c:430 switch_core_session_receive_message() Kill sofia/internal/221122(a)201.216.201.133 [BREAK] 2008-11-11 18:53:03 [INFO] switch_rtp.c:1253 rtp_common_read() Auto Changing port from 201.216.201.135:8000 to 201.216.201.133:18648 2008-11-11 18:53:03 [DEBUG] switch_ivr_play_say.c:1203 switch_ivr_play_file() done playing file So do you have an idea why after the prompt number 8 the rest are not heard?

Re: [Freeswitch-users] mod_python sqlalchemy core dumps
by . 12 Nov '08

Hi, It seems (still need to run a few more tests to be sure) you have completely solved my problem. This had been driving me nuts for the last several days, and I can't tell you how helpful this simple suggestion was! >I've used Django/psycopg + mod_python successfully in production and it >never crashes. (never tried sqlalchemy). >One thing you could try is to remove the hangup hook. That has been >problematic in the past and not well tested AFAIK. I doubt that's the >problem but you never know. After I removed the hangup hook all of my problems disappeared. Maybe it's worth adding something to the freeswitch mod_python wiki page about this? I still don't know exactly why this causes a core dump, and it seems to work ok, as long as there is nothing else interacting with it (e.g. sqlalchemy), but it probably would have taken me quite a while longer to get to this on my own, given the prominent placing of the hangup_hook in most of the examples on the wiki. >Also please load the core dump in gdb and post a backtrace.. maybe that will >reveal something interesting. (or maybe it won't). Actually you might want >to put it in a jira bug in case it becomes an involved debugging process. I did this as well, after recompiling freeswitch with # export CFLAGS="-g -ggdb" # export MOD_CFLAGS="-g -ggdb" as suggested in the wiki, however the results didnt seem very helpful: (gdb) core core.4051 (no debugging symbols found) Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1". Core was generated by `/usr/local/freeswitch/bin/freeswitch'. Program terminated with signal 11, Segmentation fault. #0 0x00e140df in ??

I'm not familiar with kamealia at all. if you don't mind, could you elaborate on why you think it would be preferable to twisted in this case? Thanks again!

I've used Django/psycopg + mod_python successfully in production and it never crashes. (never tried sqlalchemy). One thing you could try is to remove the hangup hook. That has been problematic in the past and not well tested AFAIK. I doubt that's the problem but you never know. Also please load the core dump in gdb and post a backtrace.. maybe that will reveal something interesting. (or maybe it won't). Actually you might want to put it in a jira bug in case it becomes an involved debugging process. > > I've spent hours hunting through related lists: mod_python (for > apache), sqlalchemy, etc. but all to no avail. Any suggestions or > alternatives ( I've also started looking into outbound event socket, > but there still seems to be few people using this with python/twisted > ) will be greatly appreciated. Yeah an outbound event socket framework in python would be really cool. Ideally you could write a script in the same style as mod_python scripts, and the framework behind it would handle all the communication with the switch. Kamealia might be a bettter networking library than Twisted for this one. HTH

mod_python sqlalchemy core dumps
by . 12 Nov '08

12 Nov '08

Hi, I've been having some frustrations with mod_python lately. I've stripped down the script I've been using to the barest of bare bones, and am still getting core dumps; so I've decided to share it in the hopes that someone else will be able to see where I've gone wrong. The stripped down script below does nothing more than answer, lookup a caller based on their caller_id_number and then play back some audio. I'm pretty certain that the issue is with sqlalchemy, but I'm still not clear as to why sqlalchemy should cause freeswitch to dump core and die. The database model I'm using with sqlalchemy is also quite simple, and has worked fine for almost a year with a corresponding pylons application, so I'm fairly confident that the model itself is not the underlying problem. My best guess thus far is that sqlalchemy is somehow tripping up mod_python and then freeswitch with the way it attempts to maintain connections/state across calls? In any case my setup is as follows: Python Version: 2.4.4 sqlalchemy v0.5.0rc2 freeswitch (1.0.1) [from changelog, compiled from src] Debian 4.0 etch The script I'm running (trying to run right now): --------------------------------------------------------------------------------------- # -*- mode: python; coding: utf-8 -*- import os, re, sys from freeswitch import * from datetime import datetime from time import strftime, gmtime from loadmodel import model consoleLog("info", "Current Python Version: %s\n\n" % str(sys.version)) def hangup_hook( session, what, caller_id ): """ Default hangup hook. Overload as needed. """ consoleLog("info","The application hung up for %s.\n\n" % what) return def input_callback(session, what, obj, arg): """ Default input callback for dtmf and other events. Overload this as needed. """ if (what == "dtmf"): consoleLog("info", what + " " + obj.digit + "\n") try: return arg[obj.digit] except: return None # will make the streamfile audio stop else: consoleLog("info", what + " " + obj.serialize() + "\n") return "pause" def get_current_caller( session ): """ Dig up the current caller in the database. if the caller isn't registered return null. """ current_caller = model.Session.query(model.Caller).filter_by(phone=session.getVariable('caller_id_number')).first() if current_caller==None: current_caller = model.Session.query(model.Caller).filter_by(phone="123456789").first() return current_caller class dummy_caller: def __init__(self, user_id="0", phone="123456789"): self.user_id = user_id self.phone = phone def handler( session, args ): session.answer( ) playback_dtmf = {"1":"pause","3":"stop","7":"seek:-500","9":"seek:+500"} recording_dtmf = {"2":"stop","3":"stop","5":"stop","6":"stop"} guidance_dtmf = {"3":"stop","4":"stop","9":"stop"} #3 upload, 4 replay, 9 re-record session.setVariable( "intro", "/usr/local/freeswitch/sounds/ja/test/test_intro_padded.wav" ) session.setVariable( "guidance", "/usr/local/freeswitch/sounds/ja/test/test_annai_padded.wav" ) session.setVariable( "goodbye", "/usr/local/freeswitch/sounds/ja/test/test_thanks_padded.wav" ) session.setVariable( "beep", "/usr/local/freeswitch/sounds/beeps/beep_fm.wav" ) current_caller = get_current_caller( session ) session.setHangupHook( hangup_hook, str(current_caller.user_id) ) session.streamFile( session.getVariable("intro") ) #make_recording( session, recording_dtmf, session.getVariable("intro"), process=True ) session.streamFile( session.getVariable("goodbye") ) session.hangup( ) --------------------------------------------------------------------------------------- After 2 or sometimes 3 calls this inevitably causes the following crash: --------------------------------------------------------------------------------------- 2008-11-12 12:40:08 [NOTICE] switch_channel.c:538 switch_channel_set_name() New Channel sofia/external/+818053753079(a)voxbone.com [9a56541a-b06b-11dd-8a29-191ef9635961] 2008-11-12 12:40:08 [INFO] mod_dialplan_xml.c:228 dialplan_hunt() Processing +XXXXXXXX->9993 in context default Segmentation fault (core dumped) --------------------------------------------------------------------------------------- I've spent hours hunting through related lists: mod_python (for apache), sqlalchemy, etc. but all to no avail. Any suggestions or alternatives ( I've also started looking into outbound event socket, but there still seems to be few people using this with python/twisted ) will be greatly appreciated. If all else fails I can probably switch to perl or js but I'd much prefer to stick to python if there is a workable solution ( or -hopefully- if I've just missed something very obvious ). Cheers

getDigits always missing the first digit
by Cristian Talle 12 Nov '08

12 Nov '08

Hi, I'm having some issues retrieving a dtmf sequence using getDigits. The xml dialplan invokes a javascript file that in turn runs: var digits = ""; session.answer(); digits = session.getDigits(6,"#", 5000); console_log("info", "caller entered: " + digits); ... session.hangup(); The digits variable is always missing the first digit, no matter what I do. I've added some more debug messages, it looks like switch_channel_queue_dtmf() is only called from the second digit on. Has anyone experienced this before? Thanks, Cristian

Question about FIFO event
by Woody Dickson 11 Nov '08

11 Nov '08

Hi, I am trying to write an event listener that can record the time when a FIFO consumer rejoins the queue after the caller hangs up. Tracing through all the event traffic, I notice that there is FIFO-Action= consumer_start, consumer_stop, and consumer_pop, but there isn't one that indicates that the consumer rejoins the queue after the caller hangs up. Is there anyway I can detect this particular event? Thanks for your help. Woody
