Hello,

we have recently set up a Skype for Business on-premise system. The purpose is to serve a rather small environment, only about 50 - 60 users, but because we understood that Edge Server role cannot stay with other roles on the same server, the environment consists of two servers.

While we can search in Skype for our Business users and also do find external Skype suers within Skype for Business, contact request do not come through. This means, I can search in Skype for a SfB user and send a contact request but this never arrives at my SfB client GUI. The same applies the other way round, SfB --> Skype.

Any idea from where we can start for troubleshooting?

The Edge Server can be accessed from the internet on the following ports:

TCP: 443; 5051, 5269
UDP: 3478

Edge Server is not restricted firewall-wise from accessing the internet.

kind regards,

Dieter Tontsch

Hi,

For Skype users you'll need to allow inbound port 4443:
"Addressbook service running on Skype for Business Server 2015 Front End finds the 2015 Edge by the existence of the Skype Search port 4443 in the 2015 Edge server."

Also, I'm assuming port TCP 5051 is a typo and you're using port 5061.

Yes, 5061 is a typo.

Well 4443 is accessible via Reverse Proxy as 443 --> 4443 from Edge to Frontend. But I assume this is not what what is required.

Actually, 4443 is enabled on the Edge Server (but this IP is not accessible from the internet), which is accessible by the Frontend, see attached screenshot. Is that not enough?

Actually our Edge Server has 4 physical NICs (3 in the DMZ accessible from the internet), one for Edge Access, one for AV, one for WEbConf and an internal (LAN) one for communication with the Frontend.

The internal one is the one which binds on 4443. Is this not correct?

cheers,

Dieter

Hi,

oh, I was not aware of the fact that in order to communicate Skype <-> SfB I need to first provision my on-premise Server with MS. I read the documentation, but none particulary re. to this, I rather focused on how to set up and configure SfB ...

Ok, that means I first have to advertise my service at Microsoft, sort of. I tried this, but it says that my Edge server is already registered to another organization which is the very same I just tried to register. Well, no idea, have contacted support for that.

Thanks so far,

Dieter

Hello, you where right, we have to go throuth this provisioning process. We did this now and also got "Your Provisioning Request Has Been Successfully Completed" notification from Microsoft about 35 hours ago. Unfortunatelly contact requests between Skype <--> SfB and vice-versa still do not show up.

Any ideas what else can be wrong or which log files we could have a look to?

Any other service seems to wor fine, as I said before a SfB user of my organization is found within Skype search and so does a Skype user when I do a search for exernal usrs within SfB client. But the contact requests never reach the peer client.

Cheers, Dieter
