Incoming calls are not landing on mainline

[gauravsontakke]

Hi ,

We upgraded 3cx server to the latest version, With the current setup everything was working fine but after upgrade incoming calls are not landing on our main line.

If someone dials our main line number it automatically gets disconnected within seconds without any dialing tone or error message.

Outgoing calls are working fine.

Any help will be appreciated.


Regards
Gaurav

Hi John ,

Thank you very much for the quick response. I am very new to this so apologies for missing out the basic stuff while writing the post.

• 3CX Version, e.g. Professional Annual 16.0.676
• Server OS, Windows Server 2012 R2
• Is the 3CX Server Hosted and where? On premise hosting
• Provisioning Method: Local
• Trunk Provider or Gateway Make/Model : DIDLogic/KALAAM
• Has the Firewall Checker passed: NO
• Are custom Phone Templates being used: NO

Plz let me know what could be the causes & how I can diagnose this problem .


Regards
Gaurav

Ok lets start with your trunk settings, where are you routing the call?

For my example below, I'm routing the call of my main number 1777xxxxxx to extension 000.
The extension is available and can take calls so if i call the number externally my phone EXT 000 rings
