Hi,
the Blog Post says: "The SSL certificate cannot be a wildcard"

What happens if I have a wild card certificate? Or will it simply just not work?

It won't work at all. I tried lol

 

[SweetAction]

I have to dig deeper to understand this. We use wildcards with other Direct Routing SBCs so I am unsure why we can't with 3CX.

Maybe someone from 3CX can shed some light before I go digging?

Mh, I tried with a wildcard and it seems to work...

This is news to me, I've actual spoken with people that had a wildcard, didn't work, switched to a non-wildcard and started working.
I'm glad it's working for you, but I would not suggest anyone else try it, we have seen multiple cases where it doesn't work for this reason.

Hi, I'm trying to understand how to buy "Microsoft 365 Business Voice" I can't find it in the services I can buy but I'm in one of the 70 countries covered by the service.
I would like to know if the price is lower than phone system license because I need to cover more or less 200 users...

Since "Microsoft 365 Business Voice" is a Microsoft product I recommend checking their site for more info instead.

It is not cheaper. Business Voice is 2 licenses combined: Phone System and Audio Conferencing.

If you only need Direct Routing, then Phone System on its own would be cheaper.

Hi! I finally got the damn dialpad in teams and tried to place my first call. "rejected". Checked the events in 3cx and it never reaches there... meaning, of course, a teams issue. Do you know how to troubleshoot in teams? are there any logs? googled but didn't find much.

I'd suggest creating a new thread in this category about this.

Before opening a new thread though, enable Verbose logging, then make another call. Right after you get this "rejected" message, check the Dashboard --> Activity Log to see the SIP messages that were exchanged for any clues (e.g. do you see any "603 declined"?).
Also it would be useful to know if you can receive calls from 3CX Clients to Teams, and if the issue is only in the direction of Teams --> 3CX.

Once you know this, you can open the new thread with this information.

Did you use a valid and not wildcard SSL certificate?

 

[Lantera]

Did you use a valid and not wildcard SSL certificate?

ohh.. that may be the issue? I'm using a LE certificate because it's a POC. But, if you confirm it's just the certificate, I will go ahead and purchase one for sure.

You'll need an official certificate for the SBC FQDN you chose. One valid for Microsoft: https://docs.microsoft.com/en-us/mi...g-plan#public-trusted-certificate-for-the-sbc

LE does not work as far as I know, specially if it's a wildcard one.

What @Frederick Marcoux said, there are possibly 2 mistakes here then:

1. You may be using a wildcard certificate
2. You are using a LE certificate

I suggest you read the configuration guide carefully (particularly the limitations):

I knew it wasn't supported but didn't know that won't work at all.

anyway, regarding the ssl vendor's list.. what's the cheapest so far? again, it's for a POC

It's hard to say. You can generate a true one for 3-months or something like that using sites like ssl.com and others. We did that for a 90-days cert and we'll soon buy a 1-year one.

And yeah, Microsoft refuses the connection if the certificate is not to their liking.

I know it may be out of scope and deeply sorry if it is.. but, I'm in ssl.com site and is the basic ssl (cheapest) certificate more than enough or need something extra? and, not so important, I don't see a 3 month certificate in the site.. I only see, at least,1 year. https://www.ssl.com/certificates/basicssl/buy/

 

[Evolute IT]

Well, they removed the public link to that apparently. At 37$/y tho, I'd just buy one.

Anyway, search for "ssl certificate trial" and you'll have some options.

Let me know if you're having trouble.
