OnPrem 3cx and Teams are not working

[srane.sushant]

Hello All

Here's a brief overview of the situation:

• Working Scenario: We successfully configured the integration with a 3CX hosted in Azure, and everything is functioning as expected for other clients.
• Problematic Scenario: However, when applying the same configuration to our on-premises 3CX, we're unable to make outgoing calls from Microsoft Teams. Attempting to capture logs from 3CX hasn't provided any useful information, leading us to believe that Microsoft Teams might not be reaching our on-premises 3CX.

We are using a Fortigate firewall, and we've ensured that the necessary ports for 3CX are open. Additionally, we've verified that inbound calls are functioning correctly on 3CX, indicating that the certificate is likely in order.

We are seeking your assistance to resolve this matter as quickly as possible.

Just to recap:
- Teams integration is setup with your good FQDN, SSL certificate (not wildcard) and the port 5061/5062 (depending on your FQDN.)
- Users have Teams Phone licenses assigned, and in O365 their "Office Phone" is set to an E164 DID.
- You ran the user_map script and verified the changes applied correctly?

How can I check if SSL is Good? I use teams.mydomain.co as my SSL certificate and as checked on 3cx is showing well.



Users have Teams Phone licenses assigned, and in O365 their "Office Phone" is set to an E164 DID.
Yes its set and license are assigned.



You ran the user_map script and verified the changes applied correctly?

I re-run this ps command again on 365 the issue remains the same.
