[Freeswitch-dev] High System CPU Usage due to Freeswitch Application
by Arjav Parikh 03 Feb '17

03 Feb '17

Hello Freeswitch Developers, Currently I have come through an very typical issue in freeswitch when used in Cent-OS 6 or Cent-OS 7. The issue as well as its findings is explained as below: a) In freeswitch version 1.2.3 initially calls using sipp were made using 100 cps (Calls Per Second). Everything is working fine till now i.e CPU usage for User application as well System are normal. Apart from calls no other user specific tasks are performed. Now, as soon as the value of cps is changed from 100 to 150 then the CPU usage for system gets very high upto 75% - 80%. But if we make calls initially with 150 cps then no issue observed. It means when there is a change in cps then the issue is observed. This CPU usage do not get normal until freeswitch is restarted. I have observed this scenario in Cent-OS 6 as well as Cent-OS 7. Also i took trial by disabling the tickless support as well high resolution timer support in kernel as per suggested in community forums. I have also checked in Freeswitch version 1.6.10. Still no improvement observed. b) Above setup was done in Cent-OS 5.10 and no issue was observed. Everything was working properly. Kindly guide me to solve this issue as this issue is affecting the business of our organization. In case of any more detail required do let me know. Request you to consider this issue as a high priority as it can be easily regenerated. Thanks & Regards, Arjav Parikh Software Developer - C Email : arjav.parikh(a)panamaxil.com Skype : arjav.parikh.panamax

[Freeswitch-dev] SO_REUSEPORT for RTP
by Tamas Jalsovszky 23 Jan '17

Hello, I have a few places where using a SIP (or webrtc) endpoint demands opening up the very restrictive local network firewall. Setting rtp port range would be the way to go, however usually the simple math (e.g. setting the range for 2x the number of endpoints) is still not welcomed by local network admins - paranoid ones :) My idea here is whether we could use SO_REUSEPORT in the RTP stack (I've found in sofia lib the conditional use of this option) and possibly setting a very short range for RTP or even setting only one port (I'm not sure about RTCP) as from the other side packets come from the same IP but from different port, e.g. IPclient:PortA -> IPFSserver:PortX IPclient:PortB -> IPFSserver:PortX IPclient:PortC -> IPFSserver:PortX etc. What do you think, would it be doable? If not, any other way to rapidly lower the port range to be set at the endpoint side? Regards, Jalsot

[Freeswitch-dev] Upgrading from 1.0.6 to 1.6.x
by Chad Phillips 06 Jan '17

06 Jan '17

FreeSWITCH 1.0.6 was released on April 6th, 2010, and I’ve run it in production ever since. I wonder if anyone else has stuck with it that long? :) And now, I’ve finally completed the initial migration of my system from 1.0.6 to 1.6.x. The two main pieces of work were: 1) Updating my Lua scripts to be compatible with Lua 5.2 2) Reviewing my 1.0.6 config for breaking changes, and adding 1.6.x new features The whole thing took me maybe 3-4 hours — not bad for updating almost 7 year old software. I was particularly impressed with how little changed in the configuration of the system XML files — there were only a couple of breaking changes. I believe this is a sign that FreeSWITCH was very well designed from the beginning. So kudos to you, core devs, for architecting an awesome piece of software out of the gate. It wouldn't surprise me if my next upgrade is in 2024… :P

[Freeswitch-dev] Function to construct a SQL "IN ()" query like switch_mprintf
by Podrigal, Aron 04 Jan '17

04 Jan '17

Hi, I would like to know if there exists any code that would solve constructing a SQL IN query. If not, I would like to contribute one. I think of implementing something ie `switch_sqlinmprintf` which would call `base_vprintf` with a callback accepting an array of char * and formatting them with '%Q' specifier. I would greatly appreciate any help or pointers on function names implementation... -- - Aron Podrigal

[Freeswitch-dev] Debian Packaging for Arm
by Brian C. Miller 04 Jan '17

04 Jan '17

Hi! I'm running into an issue with some of the modules during the packaging process. For instance, applications/mod_abstraction gets the following error: dh_install: Cannot find (any matches for) "/usr/lib/freeswitch/mod/mod_abstraction.so" (tried in "." and "debian/tmp") dh_install: freeswitch-mod-abstraction missing files: /usr/lib/freeswitch/mod/mod_abstraction.so The file in question is in ./src/mod/applications/mod_abstraction/.libs/mod_abstraction.so, but something isn't copying or moving it to an expected destination. I don't see it listed in debian/bootstrap.sh within avoid_mods. Is there a configuration parameter or environmental variable I need to set? Thanks! -- Brian Miller
