What tool is the display from?

413 is request entity too large. I can't say why Telnyx has decided to return this error, it could be related to overall packet size or it could be that your SDP body or content is too large, for example too many codec options being offered. Maybe connecting via the cellular data is adding...

Hi Andrew, I would be interested to know what changes you have made. I am no expert and the network ring buffer setup can get quite complex. Making changes can often make things worse. The obvious change is to make more memory generally available to the buffers with: net.core.rmem_max There...

It is not a FreeSWITCH module it is an .lua script include. Unless things have changed in more recent installations it would normally be located in the: /usr/share/freeswitch/scripts/resources/functions directory. The "require" is a relative path from the script location. I.E...

I don't know the answer but maybe the problem is codec or encryption related?

There have been a lot of changes to FusionPBX so what you can and can't do may depend on the version you have installed. We used to be able to click the little arrow button next to the IVR option box and it would allow you to put almost any code you wanted in to the box, I used this facility...

There is more than one way of doing this. The way I choose, helps to self document the link and I use a psudo DDI number based on the customers actual DDI number. Let me try to explain... I will describe one direction (PBX1 to PBX2). The real DDI belonging to the tenant (customer) on PBX2 is...

It doesn't matter how accurately you store the time, if it is the same time - it IS the same time! If you have to deal with a corrupt db, the file names of call recordings will be the least of your worries. Below is a quick and dirty hack that will allow you to fine recording file names at the...

So what happens if you get two anonymous calls on the same DID at the same time?

Windows is not a supported platform/operating system, look at the following links: http://wiki.fusionpbx.com/index.php?title=Installation https://www.fusionpbx.com/download Here are some links for the Linux operating system: https://www.debian.org/ https://en.wikipedia.org/wiki/Linux...

If it says that I move on!

Try to find out what process is using the CPU, and if the usage is being reported correctly. The top utility is a good place to start. Top will normally show you an aggregation of CPU usage as shown below: But if you press the 1 key while it is running, it will show you each CPU...

My guess it that you would need to test for the existence of active calls on any one or more of the lines. If the lines have shared appearance you would also need to cross reference the local IP address associated with the registrations from that phone. You would probably need an .lua script...

I'm pretty sure you cannot use hold music with proxy-media. https://freeswitch.org/confluence/display/FREESWITCH/Proxy+Media

I don't understand how packet loss can be 300% - 100% would be all of your packets. Maybe something is being incorrectly reported. Can you try different devices preferably not softphones? If you do suspect packet loss, try diagnosing your network at a lower level with tools like ping, iperf...

It was helping another forum member with some security questions that has prompted me to share this firewall configuration. Please do not use this unless you clearly understand what it is doing. One of the problems that I saw with the default FusionPBX iptables/fail2ban configuration was that...

Kenny, I do hear what you are saying. I have made a good start on developing my own version. I really have had enough of waiting for a stable version but, for me, it is the "member applications" that have killed it, despite being member! The member applications are basically closed source and...

It is not complicated. The default rules (/etc/iptables/[rules.v4 rules.v6]) that the FusionPBX install provides are simply the output you would get from an iptables-save or, in most cases, the rules that were in place at the time when iptables-persistent was installed. The default rules...

Just pick off the times you want to route to the IVR and use the alternate destination for the VM. Example below:
