Hi Experts,

I do have a user in my organization [SFB on prem] with several FE servers and MBX in a DAG 2016 with an unknown presence status on IM

Troubleshooting done so far

I remote into user’s PC, clear SFB cache client, outlook profile recreated, delete OAB files, reboot computer, no luck
 
User tried from another computer, same thing.
 
Fixed the discrepancy with SIP proxy address attribute
 
Any ideas?  What I missed here? Her account was updated yesterday, so OAB replication should not be an issue here.

Hello,

I need little help with renewing 3rd party certificate on Skype for Business 2015 server.
As per pictures attached, i want to renew only that certificate (SIP, since it is 3rd party and all others are from internal CA), and when i go to Request with Advanced option, and populate everything i end up with csr, that has a common name of webdir.<domain>.com, in stead of sip.<domain>.com (as it is atm).

So, the question is how to renew this certificate but to have CN of sip.<domain>.com, when there is no option to define CN?

Can I use maybe exchange server, generate CSR there, then just delete it after i get new cert, or something like that?

Regards,
Ivan.

Hi,

I have been presented with a problem. I have been requested to add a custom Active Directory attribute value to all Lync contact Cards. A large number of managers that have Active directory accounts have the custom attribute "secretary" along with the value OU location to their secretaries Active Directory Object. . Can that Active Directory custom attribute (called secretary) be updated in Lync Server 2010 and reflected on the Skype for Business contact Card? Can the ABS Configuration Tool be used for this task can a custom attribute be added to it.

Current State:
1 Forest/1 Domain
AD Connect to Office 365 (syncing password hashes)
All on-premises Lync and Exchange servers have been decommissioned in the environment

Most users have attributes like this populated - looks like this from old on-premises (However, many are synced to 365):
msRTCSIP-DeploymentLocator
msRTCSIP-FederationEnabled
msRTCSIP-InternetAccessEnabled
msRTCSIP-OptionFlags
msRTCSIP-PrimaryHomeServer
msRTCSIP-PrimaryUserAddress
msRTCSIP-UserEnabled
msExchShadowProxyAddresses

Q: Can I clear the above attributes without issue?

The reason I ask is I would like to clear the above attributes when I implement the following changes (which is the actual project at hand):

UserPrincipalName attribute    
from foo@contoso.com to foo@fabrikam.com

Mail attribute    
from foo@contoso.com to foo@fabrikam.com

ProxyAddresses attribute - the PrimarySMTPAddress
from SMTP:foo@contoso.com to SMTP:foo@fabrikam.com

ProxyAddresses attribute - the old PrimarySMTPAddress will become the secondary
from SMTP:foo@contoso.com to smtp:foo@contoso.com

ProxyAddresses attribute - the SIP Address
from SIP:foo@contoso.com to SIP:foo@fabrikam.com

Hello Experts

I have a question concerning Lync Hybrid with O365 DNS record

I working with a client and this is the current configuration of his public dns:

access  A IP Adress of EDGE Server

_sip._tls.mydomain  SRV access.mydomain   0 0 443 access.mydomain
_sipfederationtls._tcp.mydomain           0 0  5061 access.mydomain

While reading a couple of documents i read about a sip entry instead . like here : http://blog.insidelync.com/2016/08/dns-records-in-a-skype-for-business-hybrid-deployment/


 so for my Hybrid setup to work DNS wise should i recreate all in sip or  i should

sip A IP Adress Edge Server

_sip._tls.mydomain  SRV sip.mydomain   0 0 443 sip.mydomain
_sipfederationtls._tcp.mydomain           0 0  5061 sip.mydomain

Dear All,

We are running Microsoft Lync Server 2013 Hosting Pack with the latest Cumulative Update KB 2809243 (version 8308.992), published in July 2017.

Currently, and since February 2018, all our customers are facing an issue with the mobile client for iOS  (https://itunes.apple.com/us/app/skype-for-business/id605841731?mt=8) and more specifically with push notifications.

Incoming calls are not pushed to the mobile client anymore, even with the “Background App Refresh” option enabled.

Back in November 2017, with the App version 6.17.3, push notifications were still working correctly, but the version 6.18.1.x deployed in February 2018 broke the service.

I still have an iPhone 7 with App version 6.17.3 (Nov 15, 2017) where push notifications are working perfectly.

I'm sure our infrastructure is OK, and the proof is that with an older App version, everything works well.

Do you have any suggestions?

Thank you a lot

Hello Team

I have a client who has Lync 2013 On premisses and he is migrating to Office 365 . I want to know if there is any means to have an Office 365 User to add Contacts that are sitting on the On premises servers?

Is it possible and how can we achieve that?

I want to mention that the client was using this Lync 2013 just for Internal communication

We are setting up Skype for Business 2015.
In the boardroom I have setup a Laptop with Windows 10 Pro and Skype for Business to be used for Video Conferencing. I have attached a Logitech BCC950 Conference Cam to the laptop. When looking at the Preview in Video settings, you can get a stream from the camera. Once you connect a video call you get the message "Could not start Video: Your camera is not setup or you are already using it."
There are no other applications that could be using the Camera.

I have tried the following:
  1. Updated the driver to the latest that Windows updates can find as Logitech does not supply updates on their website.
  2. Installed all Windows updates.
  3. Changed USB ports. These are only USB 2.0 ports.
  4. Tried a different computer with the same setup but have the same issues.

Can anyone help?

Thanks in advance.

Microsoft Azure 2017

Azure has a changed a lot since it was originally introduce by adding new services and features. Do you know everything you need to about Azure? This course will teach you about the Azure App Service, monitoring and application insights, DevOps, and Team Services.

We use Ken's Skypeoptimzer site to create our dialing rules. we've used failover routing in the same site for this.

unfortunately an unintended result is: any external inbound call to one of our users which has simring enabled, results in the sim ring leg of the call going out via our second SIP trunk and not through the same trunk as the inbound call. this becomes an issue since our Secondary 'failover' trunk is infact a pstn gateway which cannot pass the original calling parties call id on the outbound call id of the simring portion of the call.

we do have an sbc which we can add the pstn gateway to (the same one which controls the primary SIP Trunk), the issue is this would introduce a single point of failure into the call path.

has anyone successfully managed to deal with this issue?

Hi,

I am migrating to Office 365 (Businsess Premium) from Exchange (2010 SP3 RU16).  We need to disable Unified Messaging for user syncing to work properly.  We can only have Unified Messaging for users that have plans with E3 or above.  Unfortunately users with UM disabled have no voicemail now.  Voicemail to our phone (Polycom VVX 400 and CX600) is now disabled, the phone will ring and calls can be answered but if you are not there to pick up, the call just ends or disconnects after 20 seconds or so, no voicemail option for the caller.  We have on prem Lync/Skype for Bus 2013  that is most likely needing a configuration change to resolve this.  Any help would be great!!

User wants to forward contact ceneter voicemails (separate VOIP Sysem) to xxx@domain.com,  email ID and then forward it to two different email ID

So I have informed it is not possible to forward voicemails from one mailbox to another.

So I have suggested to create shared mailbox and add the users to shared mailbox , who and all wants to monitor voicemails. Then configure shared mailbox in user outlook. So they can monitor the voicemails.

But requester don’t want to create new mailbox in their outlook. For her voicemails has to directly go to users inbox.

SO my question is can we send voicemails to DL’s. Like our team DL?

Hello,

I have parent domain : contoso.com and one child domaine : ukie.contoso.com
First, I can't create user from control panel for users located in child domain

Error: “Active Directory operation failed on “Domain Controller”. You cannot retry this operation: “Insufficient access rights to perform the operation”.

Then I can create the user with powershell.

When I try to connect my user on skype client, I have this error: You didn’t get signed in. It might be your sign-in address or logon credentials, so try those again. If that doesn’t work, contact your support team.

And error from log (attached file)

And here result when I try to test connectivity:

Test-CsRegistration -targetfqdn lyncpoolfe01.contoso.com -usercredential $cred1 -usersipaddress sip:ccharles@contoso.com

Target Fqdn   : lyncpoolfe01.contoso.com
Result        : Failure
Latency       : 00:00:00.0009741
Error Message : The log on was denied. Check that the proper credentials are
                being used and the account is active.
                Inner Exception:NegotiateSecurityAssociation failed, error:
                -2146893044

Diagnosis     :

Open in new window


Why my child users can't connect to skype on parent domain? Should I perform actions, like prepare ad or forest for this child domain?

Thanks in advance

I am trying to add another Enterprise FE Server 2012 R2 64 Bit to the Pool. While using the deployment wizard, I get the error that KB2982006 is needed. After obtaining and downloading from MS, while installing, I get the error "The update is not applicable to your computer". Research shows I need to install prerequisite updates such as KB2919442. But when I try to, I get same error for that update as well. See attachment. This machine currently has over 200 updates on it. Have anyone seen this?

If you are using MS Lync to make a phone call to the PSTN and there are multiple SIP trunks to the PSTN (actually these are trunks to Cisco CUCM and then on to PSTN from there) - how does Lync decide which SIP Trunk to use?

When a user dials in to a conference, they are prompted to enter the conference ID followed by pound.  When they do they system doesn't recognize they are entering the conference ID and the auto attendant states either that it did not get that or that the conference ID is invalid.
This is not with all phones but it is consistent on the ones that it does not work.
This is a three server frontend pool with a ACME Packet SBC and Mitel switches.
It was working perfectly then suddenly this started happening.
What might be causing this?

We have decided to use an F5 rather than the TMG (Threat Management Gateway).  After doing this external users now constantly get "Exchange needs your credentials" error.  Also my picture no longer appears.lync-cred-error.PNG
