I have my 3cx setup with IP based authentication, it works well until my IP changes (I have dynamic ip and it does change, at least it changed few times already I did try to change to register/account based but it does not seem to work. does this function work? how can I make it work so its not...

Hello folks, is there any way to permanently disable DND on fanvil phones? users by accident press on the dnd and they don't get phone calls, is there a way to disable it for user so they cannot accidentally enable it?

Exactly

Yes, usage of logs would be great where fail2ban could be used, but usage of syslog would be best since it can be directed to standard unix logging server where logs could be processed. :) awesome idea!!! On windows server usage of event logs could be utilized too probably so win users are not...

Many thanks, have no clue how I could have missed that doc :)

Where I could find those specs for wav files? Was looking but cand find it somehow to make it work for me. Many thanks for all the help as always, you are so awesome ;)

Yeah, or syslog where messages could be redirected to. But its not from what I see and the only way I could see it was in the DB. I just did not what IPs on my system which are hacking or trying to break in, thats wht for me it was easiest to access that db, pull the info and put that ip to...

Few days ago I did try to download wav files from internet so I could use them in 3cx and was not able to upload any of the wav files somehow to 3cx, wonder why, they had wav extension. :(

Ok, I like the 2nd option for sure. but I am having issue setting it up, maybe I did not understand the steps. I did create dummy extension 03 with voicemail connected to my phone gui and I was able to setup 2nd line for that extension 03, it did register the phone and I can use that second...

wrote a little bash script that I am running in my cron, after 3cx bans the IP this script takes it from db eventlog and then adds it to iptable to drop all connections for that IP to the server. Use it if you like, use it at your own risk :)

from root I can access that event log via sudo: sudo -u phonesystem -H -- psql -d database_single -c "SELECT * FROM eventlog" your system hope is the same: phonesystem <= user database_single <= database eventlog <= table

so yeah all the info is in the DB :) I think I will be able to do something about it and add the IP from event log to iptables, probably will need to run it from a crontab and block such IP for the whole system... :) will post/update on the progress if anyone else would like to do similar system...

anyway following the guide on this url and trying to increase the security as its specifies. in the slideshow, hope it will help https://www.3cx.com/3cxacademy/videos/advanced/security-with-3cx-phone-system/ I did notice there is postgres DB where I would imagine 3cx is storing all the logs...

Sorry, yes, I know about this, but its manual process, I would like automate this as this happen over night and there were quite attempts for it. I like to set it up so maybe at least on the unix level I can see the logs and put such offending IP addresses in iptable so that I don't have to...

Hi there, I have installed 3cx on the unix distro, and I am quite happy about, but recently I am seeing some hacking attempts seems like The IP 195.154.42.164 has been blacklisted for 501 sec. The IP 195.154.42.164 has been blacklisted for 1001 sec. The IP 195.154.42.164 has been blacklisted...

I am able to setup one extension to each phone, with its own voicemail. Is there a way to setup main voicemail where few phones can access? Is there ability to have few phones with the same extension? I mean its not a big deal with extension as I can have ring group setup, my concern is that I...

Thank you and appreciate your feedback on the IP addresses, it makes sense. I was just testing and did not even think of it. Yes, its easier when provider is supported, with template configuration makes it as day and night. Hope at some point you guys will support voxbeam :) what brought my...

I think I got the Caller ID figured out. I had to go to my SIP Trunk configuration then change Outbound Parameters - > "From : Display Name" to "OutboundLineID: Outbound Line Caller ID taken from Outbound called ID setting in Management console", that seems to make my Caller ID appear correctly...

Hi, have strange issue. I setup my SIP trunk, pretty straight forward after I did figure out how to call out, but I did notice that my caller ID does display incorrectly. I sent email to support and they said that its because IP address is used of "Registrar/Server/Gateway Hostname or IP"...

Ok, so I was able to test my 3cx setup with few providers, I also purchased few phones to test with and I love all of it. I currently had free license. I purchased Standard licensing for 4 lines but I made a mistake as I wanted pro, emailed 3cx about this few days ago but they did not get back...
