Multiple Issues with Calls and User Accounts in 3CX

[HungCX]

Greetings 3CX Community,

I’m currently experiencing several issues with our 3CX system and would appreciate your guidance. Here’s an overview of the problems we’re facing:

1. Calls not going through on specific accounts:
   • Some user accounts are unable to receive calls, even though their settings are identical to those of accounts that work correctly.
2. Intermittent call failures:
   • For some users, calls occasionally fail without clear reasons. The same accounts may work fine on one day but not the next.
3. Newly created users not functioning:
   • Whenever we create new user accounts, they often cannot make or receive calls at all.
4. Audio issues during calls:
   • In some cases, users report being extremely quiet during calls, making it difficult for customers to hear them.

Here’s what we’ve already tried:

• Verified user account configurations and compared them to working accounts.
• Restarted the 3CX server and SIP trunks to rule out temporary issues.

Additionally, I would like to ask how important it is to provide a phone number, e-mail address and DID for each user.
Does this effect the functionality of the system?

So has anyone experienced similar problems or have suggestions for troubleshooting? Any advice on where to look further would be greatly appreciated!

Thank you in advance for your support!

Best regards
