Looking through a PCAP in more detail - I am seeing that the INVITE packets are fragmented. I am guessing this has a lot to do with it..

It seems this is happening again, although only with inbound calls from the trunk provider (Gradwell, UK). In a PCAP I can see invites coming from Gradwell, but no response from 3cx. Bizarrely, after a while (10 seconds or so), the relevant extension in 3cx *sometimes* starts ringing, however...

Hi, This is self hosted at a remote datacentre. Phones are connected via Direct SIP. At a variety of different locations, in different countries, using different ISPs for connectivity. All Snoms - a variety of 710, 720 and MeetingPoint - running the 3cx approved firmware for each model. SIP...

Hi, I'm having some bizarre issues today where progressively all SIP registrations, and inbound trunk calls are failing. It started with one phone, but then slowly as the day progressed more and more phones dropped offline and were unable to register. I have had a look at tcpdump on the...

That is exactly the piece of information I was missing. Thank you!

It's not greyed out - in so far as it's the same style as other boxes which are checkable... but it's definitely not selectable. Clicking it does nothing.

I am attempting to allow alternative users to access the 3CX Management Console, however when I attempt to assign that right to either an existing extension or a new extension, I am unable to check that box. Fairly sure I'm doing something simple wrong?

Sorry to revive an old thread - but it would be really nice if there was a simpler way to do this, sort of a per-device DND mode.

Hi all, I'm having some problems with the rollout of a new system. 3cx is cloud hosted, and clients/phones are at a few different locations. The 3cx mac/windows/iOS clients are working perfectly. However for Snom phones, although they can receive calls (and in that situation audio passes...

Another vote for this. Authentication via SAML would be fantastic. We've more or less eliminated "independent" password databases across the company - 3cx is one of the few things that remains which isn't connected to central identity management.
