Solved Outgoing calls fail

[Psylon BV]

inbound calls work fine, outbound is not working. Installation is done by the book.

Hi! Could you be more specific?

Outgoing Calls from where?

• From the Teams client to an Extension Number of a user that has the 3CX Client?
• From the Teams client to an External Number?
• From a 3CX Client to a Team Client?
• What version of 3CX do you have installed?

Also have specifically gone through the Teams FAQ document we have created here?
https://www.3cx.com/docs/microsoft-teams-integration-faqs/
It contains most of the common mistakes that admins do and usually most of the reasons are already included in this document.

From teams to an external number. We only have one client in this setup

 

[NickD_3CX]

You didn't confirm though if you checked the FAQ which I highly recommend.

Also please confirm:

From the Teams client to an Extension Number of a user that has the 3CX Client?

Did you try this?

1. Log into the WebClient of another Extension on your 3CX different that the one you have integrated Teams with.
2. Ensure that you can make calls from this WebClient by dialing *777 and speaking into the mic, you should hear your voice back.
3. Then from the Teams Client, call this Extension Number

Does this work?

We need to determine if you have problems only calling External Numbers.

Hey

1.
I did check the FAQ list.

2.
When I call *777 in teams, i can hear my voice back.

3.
Calling internal extention from Teams work.

4.
Calling external number does not work.
It rings for 1 second and is terminated immediately

In that case, the Teams integration is just fine, the issue is with your SIP Trunk and I am willing to bet it is because Teams transforms External Number into e164 format and your provider might not be accepting this.

Can you tell me which SIP Trunk provider you are using? It it one from our supported list?
When you dial an External Number from the 3CX Client that works, can you give an example of what format you dial with?
Also please post a screenshot of your Outbound Rules.

Excellent! Glad you got it up and running.

I will mark this one as 'Solved'.

FYI, we have this advice in the Teams FAQ:
