Hello, I recently upgraded from Asterisk 1.8 to Asterisk 13. Now users are starting to complaint about packets loss, conversations are choppy!

I don’t even know where to start looking! Choppy conversations happened within users. I am using sip.conf

  • What did you exactly upgade ? Asterisk only ? Asterisk and OS ?
    How did you installed Asterisk 1.8 and 13 ? From source or from package ?

    I would be curious to see what would happen after downgrading back to 1.8.

  • Fresh installed CentOS 7.3 and Asterisk 13.13.1. Download Asterisk from here: http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-13-current.tar.gz

    I continue to see errors like this:

    Before upgrading to this new server, Asterisk version 1.8 on CentOS 5.9 hardware on both servers were similar in CPU, Memory

    Any support on this matter is appreciated!

    Thanks, Motty

    any ideas?

  • I thought it was a firewall issues. I disabled IP Tables & Selinux, but the problem persist! I have not made changes on our firewall since the upgrade!

    —–Original Message—

  • Did you setup tcpdump (behind the machine) to see, if the packets really leave the machine? Can you see any answer?

    Regards, Michael

  • CentOS 7 uses firewalld to control TCP amd UDP access.

    The iptables configuration will be overwritten and dynamically changed by Firewalld so don’t count on the old practice of manipulating iptables directly.

    I recently moved our Asterisk from an old CentOS to CentOS 7 running FreePBX 14.0.1.beta2.

    You can add a firewalld service yp /etc/firewalld/services like mine.
    [root@firewall0 services]# cat Asterisk.xml
    < ?xml version="1.0" encoding="utf-8"?>

    asterisk
    Asterisk PBX

    You then permit this service in your interface (zones) as a service

    I also added a rule to get some logging on the Asterisk ports while getting things up and running.





    I did this all on my exterior firewall which is also a CentOS 7 system.

  • SIP packet loss is one thing, RTP packet loss is another one. One does not necessarily imply the other though, of course, both may happen for a common reason.

    What about audio codecs ?
    Is it possible to configure things so that you only have a single codec enabled all over your system (trunks, phones, …) ?
    Do you still have audio issues with a single codec ?
