Calls are being re-routed mid call

One person can be in a call talking to a client and then another person on another extension talking to another client gets connected to another extension by some strange reason mixing up the calls and losing the call connection to the clients.. happening to handsets and mobile clients.. HELP!!!

it was working flawlessly for Months.. then some update got installed from 3cx, ( thought it was 15.6, but it wasn't)

I think there is a MAJOR bug in the 3cx software

Need more info on your setup.

What version of 3CX including build number

Is 3CX hosted or in house

How are you phones provisioned - manually , local lan, sbc or stun

Using custom or 3CX templates

What type of phones, are the phones running the latest supported firmware

 

[Nicholas Butler]

15.5.0 SP6
In House
phones are a mix of local lan and STUN
all templates are 3cx default
YeaLink T-48s using firmware 66.83.0.20

Would you post a 3CX Activity Log of one of these occurrences?

 

[Saqqara]

Can you narrow down the issue between the phone setup - lan to lan, lan to stun , stun to stun

How many phones are configure with stun at each location, and have you configured different ports for each phone - https://www.3cx.com/community/threa...etgear-nighthawk-x4s-d7800.54620/#post-225296

Have you ran the firewall tester ?

Have you increased the ports required for SP6 on your firewall - 9000-10999

[Nicholas Butler]

Its happening to ALL connection types, Remote and local, Mobile and Local

 

[Nicholas Butler]

I can not get a call example out of the activity log.. the time referenced doesn't show that extension even in a call.. Strange..

 

[leejor]

The Activity Log will show all calls routed through 3CX (and how they are handled), from setup to teardown. If there is no call listed, then it didn't pass through the PBX.

and type of provider - Gateway or VoIP/SIP...

 

[Nicholas Butler]

Im using Wiretap Telecom SIP very simple setup
