Crash whilst making multiple outbound call attempts
by Andy Ayers 18 Mar '13

18 Mar '13

Hi, I'm running Freeswitch 1.6 and everything has been running incredibly smoothly for many months until I recently extended the functionality of my application to make outbound calls on a schedule handled by PHP. It all works fine when the volumes are low (10 calls every 5 minutes is stable). When I try and ramp up the volumes to do more calls Freeswitch intermittently crashes with no indication in the log files as to why. The log comes to an abrupt halt and the last action in the logs is something different and seemingly harmless every time. Here's a little more info about the setup: I use a cron job on my Linux Debian box to run a php script via apache. This script looks up queued calls in a database and then uses rpc to instruct freeswitch to make the call by executing a javascript script. The calls are originated in Javascript using this function. function MakeOutgoingCall(from, fromName, to) { logMessage("Initiating outgoing call: {originate_timeout=40,effective_caller_id_number=" + from + ",origination_caller_id_number=" + from + ",origination_caller_id_name=" + fromName + ",ignore_early_media=true}sofia/outbound/" + to + "@sip.node4.co.uk"); var newSession = new Session("{originate_timeout=40,effective_caller_id_number=" + from + ",origination_caller_id_number=" + from + ",origination_caller_id_name=" + fromName + ",ignore_early_media=true}sofia/outbound/" + to + "@sip.node4.co.uk"); return newSession; } There's a fair bit goes on during these calls but nothing fundamentally different to the many inbound calls I've been hadling very successfully so far. Can anyone suggest what the likley causes of such a crash might be or where I might look to get more information from the systrem that would give me a clue. Apologies I'm no Linux expert. Initially I thought it might be the voicemail detection but turning this off has made no difference. Does this simply point to a hardware fault on my Linux box? Any help greatly appreciated. Many thanks Andy

Interrupting the playback in the middle and start recording(Not interrupting by using playback terminators)
by Nikhitha 18 Mar '13

18 Mar '13

I want to do the following... 1. Play a long music file from a dialplan. 2. While the music is playing, If the user is not interested in listening to that wav file can start recording For example if it is playing "Do you want to continue the service then say yes or else say no,Please give some input" ,then user is not new to the service so without completion of playing it,can the user start recording like saying "yes/no"? Can we record it while the wav file is being played,is there any chance of interrupting it and proceed to recording the file(Not interrupting the playback /recording using anything like playback terminators).. How do i do this.?? Thanks in advance.. -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Interrupting-the-playback-in-… Sent from the freeswitch-users mailing list archive at Nabble.com.

Yes, you can implement this using ESL as well. /Peter -----Ursprungligt meddelande----- Från: freeswitch-users-bounces(a)lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] För Nikhitha Skickat: den 18 mars 2013 08:12 Till: freeswitch-users(a)lists.freeswitch.org Ämne: Re: [Freeswitch-users] Interrupting the playback in the middle and start recording(Not interrupting by using playback terminators) Can i implement the same even for ESL? -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Interrupting-the-playback-in-… Sent from the freeswitch-users mailing list archive at Nabble.com. _________________________________________________________________________ Professional FreeSWITCH Consulting Services: consulting(a)freeswitch.org http://www.freeswitchsolutions.com FreeSWITCH-powered IP PBX: The CudaTel Communication Server http://www.cudatel.com Official FreeSWITCH Sites http://www.freeswitch.org http://wiki.freeswitch.org http://www.cluecon.com FreeSWITCH-users mailing list FreeSWITCH-users(a)lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org !DSPAM:5146ba4332761722676381!

Hi Vitalie, Thanks..It worked. I want to know that, is python supported as an IVR scripting lanuguage with the stable release (current) of freeswitch. I can see on the mod_python wiki page that the documentation needs to be re-done as there are a lot of changes. Where can I find the latest documentation about mod_python? Please guide.

Hello, Not sure why but recently I noticed that Freeswitch is logging data with the wrong date I noticed it first in the freeswitch log but I can see it also in the log that are display in the cli itself the computer itself is ok ~# date Sun Mar 10 20:13:05 EDT 2013 but : freeswitch@internal> version FreeSWITCH Version 1.3.13b+git~20130108T204816Z~8e892abdef (git 8e892ab 2013-01-08 20:48:16Z) freeswitch@internal> strftime 1999-12-31 19:07:40 from freeswtich.log 1999-12-31 19:14:09.460477 [WARNING] sofia_reg.c:1506 SIP auth challenge (REGISTER) on sofia profile 'internal' for [1000(a)xx.xx.xx.xx] from ip xx.xx.xx.xx This is right after a reboot since I thought a reboot would may be fix it where does FS takes its time from?

Freeswitch translates "480 Temporarily Unavailable" as 200 OK and then BYE
by Camila Troncoso 15 Mar '13

15 Mar '13

Hi, I have a this call : * PROXY FS DEST* INVITE INVITE 100 Trying 100 Trying 183 SDP 183 Session P.SDP 480 Temporarily Unavailable 200 Ok DP ACK BYE When I receive a “ 480 Temporarily Unavailable” after a “183 Session Progress with SDP” FreeSWITCH tries to hang-up the call normally by sending a 200 ok and then a BYE response. But the call was not effectively established. It is generating problems in my proxy server. Is there a way to relay the 480 response or to change it to some other more accurate response.

SaltStack + deployment techniques
by Cal Leeming [Simplicity Media Ltd] 15 Mar '13

15 Mar '13

Changed topic to be more relevant.. Agreed, saltstack is wonderful.. we're using it in combination with Atlassian Bamboo with a similar outcome, we push a release button for a specific workflow, and salt takes care of all the steps; * Compile stack components into deb packages (for example freeswitch, backend web applications etc) and place on local mirror * Performs unit test in the build steps * Fire up a bare instance with salt taking care of installation and ensuring services are running * SIP balancer (freeswitch) moves traffic between the switch instances to allow for rapid release fail over, and a real staging environment.. if there is a problem with a release, we can quickly switch back to the previous release at the LB.. if there is no problem, the old release instance is terminated * Traffic balancer takes care of moving traffic between the API/MySQL instances * Stack runs uwsgi/django/nginx/freeswitch * We use new relic / pingdom / cacti for monitoring * Code is kept in GIT I'm still not entirely happy with the overall procedure and always looking for new/better ways to improve it.. but SaltStack is a clear winner, leaving puppet/chef in it's dust.
