Not seen this happen before, unless you are upgrading / running app_defaults etc. I have a few modified lua scripts and they don't get overwritten. What version of Fusion are you using? You could try changing the permissions on the file so it is readable by everyone but only writable by root.

${domain_name} is a channel variable. user_exists is a global dialplan used by all domains. The domain_name variable is set from the context. If user_exists is returning false, then look closely at what the call is asking for, double check that the user (extension) does actually exist within...

Don't do faxes much nowadays but in the past I have grabbed the logo from a webserver, setting the value to an http:// link always worked for me: Category: Fax Sub Category: cover_logo Type: text Value: http://mysite/mycompany.png Enabled: true

Hi @francois , The implementation is very simple, but bear in mind that this is implemented on my SIP Trunk platform which uses OpenSIPS, not FusionPBX or FreeSWITCH. An set of iptables rules to implement hit counters could be set up as follows, make sure the counters are above any rule...

Hi @mattswainston I tried to replicate your fault on version 4.5.27 but it all appeared to work fine. What version are you running? Have you tried adding the lua line using a different PC/Browser?

Thank you for sharing the patch, I now understand what you have done. Yes I think you probably would need separate SIP profiles if you have a mix of mediasec and non media sec providers.

@bcmike I had not heard of LiberNMS, I will take a look. Thank you for the link.

BLF is a real issue, I have one customer with over 200 endpoints all with groups of BLF. The BLF NOTIFY messages account for most of the SIP traffic for that tenant, way more than calls! Also when each phone registers, sofia has to send out loads of subscription notifications, all adding to...

It is a tough question to answer. Many people struggle with this because there is no "rule of thumb", each individuals situation is different. Not all customers are created equal, what I mean is some will just make calls, but others may have lots of BLFs etc. and this makes a big difference on...

FusionPBX works out CPU usage, by adding (sum) up the percentage CPU used for each running process: ps -A -o pcpu It then counts the number of CPU cores: grep -P '^processor' /proc/cpuinfo Then it simply divides the sum of all the CPU usage by the number of CPU cores. It is a reasonable...

I don't think you would need another profile, I imagined just adding your new sofia parameter to the existing external profile, example screen shot below:

The devices record is just a collection of data that defines how you would like to provision the phone. User ID and Auth ID are often the same but they dont have to be, it is the Auth ID and password pair that is important for authentication. You would normally enter the extension number in...

Have you found the documentation? https://docs.fusionpbx.com/en/latest/accounts/devices.html https://docs.fusionpbx.com/en/latest/hardware.html The devices menu/application is just for auto configuring devices, it has nothing to do with the operation of SIP. Devices are identified by their MAC...

@bcmike Thank you for the "heads up". A minor version change may just drop in without doing very much to Fusion.

OK, You don't explain what you have done. But my guess is you will need to look at the definitions for sofia_config_t and the sofia gateway struct. If you allow the xml loader (switch_xml_load) to know about your extra configuration, then you will be able to set (Add) your defined config item...

Yep, that would do it. We only have one DC that is IPv6 capable. Here in the UK, ISPs and DCs have been very laggard in their approach to providing IPv6.

Ok, how did you implement it? Did you modify the mod_sofia code?

The "Chain f2b-" entries are the fail2ban jails, there is nothing in any of them. Good to look though. You will need to do some basic network diagnostics ping etc. to try to find out what is happening.

A 408 is a request timeout so your SIP packets are not getting from end to end. There could be lots of reasons but one of the first things to check is Fail2ban. If you log in to a shell on your server and issue an iptables -nvL you will quickly see if the IP address for your Bria is in a jail.

I assume you are referring to RFC3329 maybe? I'm pretty sure Sofia parses, passes and supports the Security-Client: Security-Verify: headers. I always thought it was up to the UAC to generate them, not something you would configure in a gateway, unless, of course, you mean adding them to the...
