Microsoft Lync Server (renamed Skype for Business Server in 2015) is a real-time communications server software that provides infrastructure for enterprise instant messaging, presence, VoIP, ad hoc and structured conferences (audio, video, and web), and PSTN connectivity through a third-party gateway or SIP trunk. These features are available within and between organizations, and with external users on the public internet or standard phones (on bpth PSTN and SIP trunking).

Skype for Bossiness 2015 environment.
Users are unable to join meeting when they are travelling and see the error as shown below:
Skype.JPGOn the Edge server all services are running except the Skype Audio/Video Authentication service.
When I start the service it says that the service started and then stop and that some services do that.
Should this service be in running state?

We had a cert expired on this server and was replaced.
Users are saying issue started after that.

On the Edge server I see some of these errors:
"A fatal alert was generated and sent to the remote endpoint. This may result in termination of the connection. The TLS protocol defined fatal error code is 10. The Windows SChannel error state is 1200."
But this error has been therein the past.

How can I test the meeting connectivity with powershell or otherwise.
And what else can I look for?

For one of our users external Skype/Lync contacts have all started coming up as "Presence unknown" and the user is unable to call or message them. Prior, the user had no trouble contacting them.
What should I check to resolve this issue?

Lync 2010 Migration:

We are currently in process of domain migration from domain A to domain B. We have 2 way trusts enabled between the 2 domains and all the users and computers are moved to new domain. We are currently migrating services and have to migrate LYNC 2010 running on domain A.com (no federation, edge etc) just Front End.

Lync 2010 running currently on domain A.com and FE server joined to domain A.com

As we have to migrate Lync with all the users from A.com to B.com, what should be the approach and the technical steps for migration. We have already installed fresh server on domain B.com

If you need more info, please feel free to ask.

Skype for business 2015 Yealink T48S | Trusted Certificate
I need assistance with phones we recently purchased, all T48S handsets with Skype for business firmware.
 
I have tried all 3 latest available firmware and stuck with this version as it offered a simpler login screen for users.
firmware
Scenario:
Phones register correctly for as long as the the trusted certificate is not present.
Periodically the handsets will populate with a CA certificate on line 1 even though everything is set to disabled below and then the users are unable to sign into the phones.

securitypage

i did some googling and found this command but its only relevant for SKype for Business online
https://docs.microsoft.com/en-us/powershell/module/skype/set-csipphonepolicy?view=skype-ps

What is causing the phones to download the internal root domain CA certificate?

I am running Lync 2013 with a single frontend server. I have all the DNS records properly created in the right zones.If I am connected externally with no VPN connected, I can sign in just fine. However if I connect the VPN, I cannot sign in. If I sign in before connecting via VPN, the connection to Lync stays up. Any idea what's going on? I have included my failed sign-in logs from a laptop:

Dear Experts,

I am trying to use powershell to clean a CSV file from certain values. The output of powershell is normally like this


Name                                                                                                            $_.AgentsByUri                                                                                                                  
----                                                                                                                             --------------                                                                                                                  
ResponseGroup1                                                                                         {sip:user@domain.ca, sip:user2@domain.ca}

I want to clear the csv file from the {sip:} And leave users with their uri only. So the output would be like the following

Name                                                                                                            $_.AgentsByUri

Skype for business/Lync 2013

We purchased a Skype for business system about a year ago and are still having alot of problems with it.  The service provider seems to be getting no where in resolving them.  the biggest problem is hunt groups and park service being very slow.  heres a bit of background:

Yealink T46G deskphones connect directly to SFB server
Gigaset cordeless phones connecting via SIP connect to AudioCodes SPS server
4 loud ringers connecting to AudioCodes Loud ringer

the problem i have is when a hunt group is called it takes about 5 seconds before the phones even start to ring, then when the call is picked up it takes another 5-12 seconds to connect during which time the hold music cuts off so the caller gets silence.  usually they think the line has cut off so they hang up.  then once the call is connected it is then a further 3-4 seconds before the audio actually connects.  this is causing a major problem and to pickup another persons ringing phones takes even longer.

if a call comes through on a DDI howeer the pickup is instant.

it only seems to relate to calls going through the park serivce.  does anyone have any suggestion as to what I can check/change to improve this as, as i mentioned, the service provider is getting nowhere with it.

We have a Lync 2013 server and clients are using Skype for bussiness client.
A Distribution List's email address was changed due to spam issues on the exchange side.
But users had saved this Distribution List (DL) in their contacts in the Skype client.
As a result now they get the in the skype client that either the specified contact does not exist.
On one users client we deleted the saved contact and searched address book and he could find it fine.
This confirms that the error was due to email address being changed on the DL.

So now the issue is how to clear this old DL contact from all users in the company either through script or GPO.
LInk below shows the procedure on how to re-download the address for a client:-

If use GPO to push out registry setting and a login script to clear out the old address book files from Lync folder the would it also get rid of the saved contacts from the Skype client?

Or is there a better way of doing it?

Wondering if anyone can either simplify this or make a suggestion. Currently we have exchange 2013 and have it connected to our on-prem pbx so our vm are hosted by exchange 2013. This has been working well. We are switching to office 365 this year and I was going to implement exchange online UM using a session border controller to connect to our on-prem pbx.

Now I see Microsoft is retiring exchange online vm December 2019 so I am looking into what replaces it. And I am getting very lost and confused. I’ve been reading about cloud VM, teams, skype and direct routing etc.

I asked Microsoft and they just sent me a bunch of links on how to configure on-prem Pstn with Skype.

Can anyone explain in layman’s terms what I need and/or if you have a suggestion of something else that would work as well as the 2013 UM, I’m open to that as well.

Thanks

Will AD Schema Update from Window 2008R2 (Version 47) to 2016 (version 87) impact Lync Server 2010?

(The Forest and Domain Function Level is not being changed, they will remain at its current version (2008R2) but may be updated as part of a future change.)

Our Active Directory team is proposing to update the AD Schema version from Window 2008R2 (Version 47) to 2016 (version 87) and we need to know whether impact Lync Server 2010 or require any remedial actions to be required?

Hey guys looks like Microsoft forced one of our clients into using Teams for Microsoft :(

Is there a way to create contact groups like you could in Skype for Business?

The best thing that I can find to do is to search for people and make then favorites.

We are running an on prem Skype for Business server that was only used internally for IM and meetings. It was a 1 server setup and all worked great.
We now want to add an edge server so we can host skype meetings with external clients
The edge server is in our dmz and not a domain joined server
I edited my topology and added the edge server and published the topology. I then exported the config to a zip and imported it during the installation of the local configurations store. after running all was fine with the green checkmark and the complete.
I ran the setup for server components, requested and added a cert form a online auth. all went fine also

Everything installed fine except the server keeps giving topology errors saying it cant find info on the local domain
Has anyone seen this before?

Lync 2013 with Exchange 2013 - The Lync Contacts that sync over to our Android and iOS mobile devices end up with a " + " prefix on the phone numbers. This causes the call to fail, as this makes it look like an international call to the phone carrier. You can manally Edit and remove the + sign, but I would like to prevent the issue entirely.
   I haven't found anything online yet on the subject, but I will keep looking. Probably my syntax.
   Our Mobile Device Management system is Mobile Iron, but I am thinking this must be an issue relating to Lync 2013 and Exchange ActiveSync.

Thanks!

In Skype for Business Server 2015, Is there a way to disable clients from retrieving location information from the LIS/Secondary LIS every time the client registers with the server? I want to prevent the client from performing a HELD request to get location information when it first registers to the server. Is this possible with the on-prem server?

Is it possible to disable the voice feature of the exchange's automated unified communications operator, without removing the transfer configuration to marked extensions directly?

For example, if a customer dials the IVR, "Thank you for calling PCH, if you know the extension number, mark it now, otherwise the menu is the following, to call sales, dial 1, support 1, administration 3"

When I disable the aforementioned option, the part of "If you know the extension number, check it now" does someone know how to avoid this problem?


I would appreciate your support.

Greetings.

I have to install Skype for Business 2015 server for one of my client but for S4B Edge server there network team is not going to allow internal network IP to be assigned to Edge server's internal NIC placed in DMZ,. I want to know can we assign DMZ subnet's IP to both internal and external NIC of edge server? And then will allow communication between internal edge NIC and Frontend Server.  Will this work that way?

Hi Everyone

I was asked to look into a Task which I'm not sure if it's possible. I have a Lync Server 2013 Enterprise.

Is there a way to set a few users with a specific policy which will allow them to Contact internally only certain users, and Block to Contact anyone else.

This Solution can contain a new Pool in Topology or I'm wondering if there is an option I can achieve them under one Topology.

Also Would be there options like that in Later Skype For Business version.

Hello Team

I need some advice regarding Lync 2013 Edge Server and 3 External NIC addresses.

I want to change in our Company the Edge Server Configuration to use instead 1 Public facing NIC Card, 3.

It's so far I see a recommendation from Microsoft to have for each Service a separate IP.

I have some problems when I try to configure that and hope you can point me  if I'm doing something wrong:

Infrastructure Summarize:
(Ip addresses are only examples)

I've one IP address facing LAN 172.168.1.2

I got now 3 IP addresses facing Public internet:
172.169.1.1 (Access Edge)
172.169.1.2 (Webconf)
172.169.1.3(AV).

For the above addresses I have seperate Public addresses assigned and NAT'ed

156.168.1.1 <> 172.169.1.1
156.168.1.2 <> 172.169.1.2
156.168.1.3 <> 172.169.1.3

External DNS:
I created one DNS entry for sipwebconf.domain pointing to 156.168.1.2, and DNS record to point to av.domain 156.168.1.3

Certificate contains required webconf SAN. FOr Test i also included the AV.

Problem:
Whenever I setup In the topology of the 3 IP addresses, Audio or Video is not working if someone externally joins a Meeting.

Peer To Peer connection with Federated partners work fine.

Everything works fine If I use 1 IP address and the web conference service set as 444.

How I'm setting up the Topology:
In the Access Edge service as DNS I'm using my sip address and the IP 172.169.1.1
In the Webconferening as DNS im putting …

We are just starting to use Skype For Business for Internal IM.   We have setup Skype For Business to not allow External Contacts to be added. We didn't want Employees to start chatting with Friends and Family while at work.

We are looking to get rid off WebEx for Presentations and wanted to use Skype For Business, though it looks like we can't Invite Customers to the Meetings since we blocked External Access.

Is there a Way to Block External Users for IM, though Allow Inviting External Customers for Presentations?

Thanks!
