Lync Server 2013 calls lost or cannot be retrieved when put on hold.

Out of the blue last week calls on our Lync server started dropping or getting stuck when placing them on hold. This is calls that come from the PSTN into our server. Looking at some call traces, I can see that the INVITE request to put the call on hold
to the gateway looks about right with an SDP attribute of a=sendonly. The issue seems to be that the SIP/2.0 200 OK response from the gateway is lacking the SDP response attribute of a=recvonly. It also looks as if it the gateway is not recognizing the first
session and trying to create a second session. If we are lucky that the call is not dropped after the initial invite/response, we can then press hold/resume and the call will finally get picked up. I'm pointing my finger at the gateway on this one. The gateway
is provided from our ISP and we connect directly to it. Any other Ideas on why a call would do this with the gateway? Appreciate any insight.

Hi,
Please check if there is any error message from Mediation Server.
From Lync Server side, please double check normalization rule. If the normalization rule not set suitably, it may cause call fail.
Please check the network situation.
Also, you need to check the configuration on gateway.

  • The Director role is optional in Lync Server 2013 - could anyone please explain why the director server has lost its importance??

    Could anyone please explain why the director has been removed from spotlight as it had much importance in LYNC 2010 and now being an optional role in LYNC server 2013.[any call flows regarding director servers would be much useful]

    Hi SJ Praveen,
    A Director is a server running Lync Server 2013 that authenticates user requests, but does not home any user accounts. Lync 2013 Front End servers have the same registrar service and functionality
    as the Director.
    The Director isn't providing any special functionality. If the Director goes down, all pools would become inaccessible when the clients queried DNS for the SRV record until an administrator
    makes a manual internal DNS change that points users to a Front End pool to handle the sign-in request from Lync clients. Microsoft has made the Director functionality relevant for organizations that have specific security requirements, such as allowing all
    external users to register to a specific internal server instead of the Front End servers. This server role is merely optional and not needed for most Lync Server 2013 deployments.

    please verify your computer name while you creating FQDN pool FQDN of Server name
    example
    computer name
    is server1
    domain name is abc.ae
    so,
    your FQDN pool name will be server1.abc.ae
    problem solved :)

  • Make Call Fail on B2B in Lync Server 2013

    Hi,
    I am facing an issue while working with Lync server 2013.
    My analysis on the issue is as follows:
    Lync Client 2013 (SIP Scenario) :
    1) Invite from UCMA application to Lync Server and then to reach Lync Agent.
    2) Trying
    3) 180 Ringing
    4) "488 not acceptable here" responded by the Lync Server
    Lync Client 2010 (SIP Scenario):
    1) Invite from UCMA application to Lync Server and then to reach Lync Agent.
    2) Trying
    3) 180 Ringing
    4) 200 Ok (Lync Agent attends the call)
    The scenario works properly with Lync Client 2010 and Lync Server 2013.
    But the same doesn't work with Lync Client 2013 and Lync Server 2013.
    Kindly revert back with a possible solution ASAP.
    Regards,
    Harish

    Hi,
    Make sure Lync 2013 client update to the latest version and then test again.
    If the issue persists, you might post the issue on Lync MSDN forum and more developing expert will help to solve the issue. Thank you for your understanding.

    The Real Problem is that my Lync HP 4120 Phone can't make a sign in, not from USB cable loging, nor with PIN authentification
    When I try to make a login with the USB cable, I set the user and password and the phone says "Connecting to Lync".. "Downloading a certificate" ... "Installing certificate"... "Downloading Certificate"...
    "Installing Certificate".. forever 
    When I try to make a login with PIN Authentification, the phone first displays the following:
    Account used is not authorized, Please Contact your support team and then shows this:
    An Account matching this phone number cannot be found. Please contact your support team.
    The Pin authentification is enable
    In the Lync Server Enable Kerberos Authentification, Enable Integrated Windows Authentification and Enable Certificate Authentification are enable
    This is the configuration from DHCP

  • How do I enforce "Show My Picture" instead of "Hide My Picture" in Lync Server 2013?

    I was scouring TechNet and the web for a script that could perform the same task as one that I previously used for Lync 2010.
    In Lync 2010, we had already used Lync policy to enforce that only the Active Directory photo could be used. One thing that we couldn't set via policy however was the ability to complete remove the "Hide My Picture" option in Lync 2010 client.
    This left users with the ability to freely switch between showing the Corporate photo or no photo. I did eventually find and make use of script that constantly checked for this setting switch, then switched all users back to the desired "Show My Picture"
    setting. I don't recall who wrote it, but it's easy to find on technet. As we started to move more and more users to our Lync 2013 enterprise pool, I noted that even though the script was running, the setting seemed to be changeable. A closer look revealed
    that the script didn't function correctly against SQL for our 2013 pool.
    I took the concept and applied it to Lync Server 2013 after studying the differences in Userdata. In Lync 2013, because UserData is in .zip, you need to convert it to 2010 format XML to use logic intended for Lync 2010. My script will extract 2013 data,
    convert it to 2010, query for users who are set to "Hide My Picture" and then export any guilty users to an edited2010 XML. The script then converts this to 2013 Format .zip, and uploads the data for these users only. I chose to use Update-CSUserData
    insted of Import-CSUserData as this avoids having to restart my Front End. I then use a scheduled task on my Front End server which runs this script every hour.
    Please note: You can use this script, but I guarantee nothing about it's functionality, and I am not responsible for how you positively/negatively use it. You should always test things in a Lab Environment. Furthermore, this script was run on a relatively
    smaller Enterprise system in which we are by default set to "Show My Picture" and already assigned as part of our user policy the ForceADPhoto attribute. This means that running the script is less intensive on my FE than say on a FE with 10,000 users
    where none of the users were set to "Show My Picture". Please keep this in mind when planning to execute against your FE. You may want to edit my script and insert the -UserFilter or -WhatIf in the Export-CsUserData UpDate-CsUserData.
    Anyways, I hope this solves the similar issue for many of you Lync 2013 administrators. Please feel free to share my work with others if it does, and also give this post some good feedback and/or mark my post as the answer to your problem.

  • Microsoft Lync Server 2013, Backup Service user store backup module detected items having pool ownership conflict during import.

    Dear Team,
    I have two Enterprise lync 2013 pools, abcPool and abcpool1. abcPool1 has got two servers, Server1 and server2. and abcpool has one FE server named "Server 3". and they have pool pairing.
    Replication was fine between them when i had only one FE server in each pool, one day FE service broke on one of the FE server on abcpool1 and failed to start so i had to do failover to another pool, at that time i introduced one more FE in abcPool1, that
    why now 2 FEs in abcPool2. Server1 FE service was resolved by reinstalling the binaries. However after that im unable to get the backupservice state to normal, i tried the below articles with no luck,

  • How to reinstall Lync server 2013 Core Component Server Applications

    Hi Would like to know how to register back the core server applications and where can i find the priority list. I incidentally
    removed the server applications (ClientVersionFilter, IIMFilter, VoIP Apps and EumRouting and Outbouding) when i removed my MSPL script application from the pool. I missed out to put my script
    app name after pool name when i run the command remove-cstrustedapplication. Then, it removed all the core apps from that pool.
    I found that .am files and .exe files are still in the C:\Program Files\Microsoft Lync Server 2013\Core and tried
    to register back using cmdlets but not very sure about the priority of the apps. Or can I install RTCHost.exe? Now Outgoing call is not working. Please kindly help. Thanks in Advance.

    Oh.. thank you very much both
    Saleesh and Eric. I will try it. 
    What I did is that I used the cmdlets New-CsServerApplication and registered the server apps (checked the server apps
    list from testing fe server) like how I register MSPL script app. But I may miss out some components since testing fe server uses Standard Edition. I registered my
    MSPL script app back too, but after a while Lync Front End Service keeps on stopping.  I am not sure that
    MSPL script or missing components which one causes to stop front end service. Now I am checking the event viewer logs.
    If I run add-remove Lync component wizard on the server, will it remove any other settings like removing users from
    pool? or it just install/unstall lync server core components only?
    Many thanks!

  • How can I connect the phone network to LYNC Server 2013?

    Greetings,
    We have a working implementation of Lync Server 2013 (pc to pc), our objective is to connect lync to our phone central, receive and send calls from lync clients (pc, phone, etc), basically enterprise voice services.
    I would like to know the following:
    Hardware that I need for this beside the server.
    Extra configurations that must be done.
    If you could recommend me the hardware needed it would be helpful.

    You'll need a gateway typically. You can find a list of qualified IP gateways here: http://technet.microsoft.com/en-us/office/dn788945.aspx
    I typically lean towards the AudioCodes Mediant line, though many here love Sonus as well.  You'll need to pick a method to connect to your PBX before you begin, such as via a T1/E1 trunk, FXO ports, or a SIP trunk depending on what your PBX will
    support. 
    You'll need to configure the PBX to route calls through the T1 towards Lync and vice versa.  You'll also need to configure the gateway itself, so I'd go with a consultancy with experience here or purchase remote implementation support from the hardware
    manufacturer.
    On the Lync side, you'll need to configure dial plans, voice policies, usages, and routes:

  • Contact Groups in Lync Server 2013

    HI,
    I have deployed the Lync 2013 server . I can successfully login to Lync client 2013 using lync server 2013. But i wan to create a group list/group  on server side and all clients/user i will add in this list/group. After login to Lync client this group
    will show on all the user on client side. In office Communicator 2007 R2 i had created the same requirement. But in lync 2013 server i did not find this kind of option.
    Help me on this
    Thanks 

    I would recommend you combine Exchange Server and PowerShell script.
    You can put all AD users enabled for Lync Server to a Distribution Group, then add this group to a reference account. Export the contact information to other Lync users.
    You can refer to

  • 2 Problems using lync client andriod conncet to lync server 2013 ( contacts status is Presence Unkhown)

    Hello Everybody
    I have installed lync server 2013 in my lab . Everything is ok . but internal mobile client in my LAN can not work with lync !
    I installed lync server 2013.
    I create 2 DNS record to lync-server : lyncdiscoverinternal and lyncdiscover.
    clients  on PC (windows) work and everything is ok . when user use Anroid phone , cleint connect to lync server and list connnact list .BUT when Send IM to contact or start video call come this error :
    " Failed to process the server response.Please try again . if the problem persists,contact your support team."
    This is first problem. Another problem is the contact list for every user status  is "Presence Unkhown" !
    No online , No Offline and all of contact status "Presence Unkhown" !
    If i had to config mobility in in lync server 2013 ? or mobility service built-in in lync server 2013 ?
    please help me .

    Hi Meysam Halvaei,
    As Thamara mentioned, you need to deploy reverse proxy.
    Lync 2013 mobility clients are using a separate dedicated Ucwa parameter the URL is the same web services location as provided by the
    External/Ucwa parameter.
    You need to have a look at the following diagram.
    The Lync 2013 mobile client will need to connect with the external web services. The way Lync is designed this communication is always established using HTTPS/TCP 443, so the traffic
    will need to pass through a reverse proxy or similar service that will take this communication and forward it to the server hosting the external web services, now using port 4443 instead.
    Best regards,
    Eric

  • What are the supported feature for LYNC Server 2013 WITHOUT Telephony

    Hi
    I have a new customer who is asking for LYNC Server 2013 without to use VoIP Support.
    The would like to use the LYNC-SKYPE connectivity but without LYNC calls.
    Most of their internal users are using SKYPE.
    The Question is now, what Features are possible for example:
    FEATURE-LIST
    See other’s presence
    Manage own presence
    See presence in Office
    Contact management
    Contact card
    PC-PC and multiparty IM
    PC-PC and multiparty file transfer
    Persistent Chat
    PC-to-PC computer audio calling
    PC-to-PC computer video calling
    PC-to-PC presence display, IM, audio, and video with Skype users
    But what of the above feature list is possible without using VoIP ??
    And how works that LYNC WebApp Client without VoIP? Is it possible to route Audio/Video over the internet by using that LYNC WebApp Client in LYNC 2013??
    Thanks in advance ;-)
    Kind regards
    Michael
    Kind regards Michael Damaschke

    All of that is possible without PSTN connectivity or the plus cal.
    When you say VoIP, do you mean audio chatting over TCP/IP in the purest form, or do you mean specifically telephone calls?
    Technially PC-to-PC computer audio calling is VoIP, or voice over IP, but if you're talking about connecting it to a PBX or the phone network, you don't need it for any of the above.  It works wonderfully and is quite a bit cheaper without it due to
    fact that you won't need to license the plus cal for enterprise voice or the Exchange enterprise cal for voicemail.

  • What port number for Desktop Sharing using in Lync Server 2013 and Lync Online

    Dear All,
          My environment using Lync Server 2013 and Lync online on Office 365. I don't want my user using Desktop Sharing feature. then I need to know what port number for Desktop Sharing using in Lync Server 2013 and Lync Online.
    I will deny this port on personal firewall each client.
          Thank you for your advise.

    Hi,
    I'm not sure you'd be able to do this with ports without impacting other application sharing features such as Q&A, Whiteboard, Poll etc - I'm pretty sure they all come under the same umbrella of ClientAppSharing.
    Ordinarily you would create or modify your conferencing policy to restrict sharing to single programs only using a cmdlet similar to below;
    Set-CsConferencingPolicy -Identity "Global" -EnableAppDesktopSharing SingleApplication
    This would disable desktop sharing but enable users to continue sharing other single programs. If you want to remove that functionality too, then replace the 'SingleApplication' parameter with 'None'. Then users won't be able to share any programs either.
    This is the correct way to do it as the icons will be greyed out for the users. Doing it your way, they would still be able to click them, and it would throw an error - this will lead to a lot more support calls and people assuming a service is broken.
    I hope that helps some.
    Kind regards
    Ben

  • Error Upgrading from the Evaluation Version of Microsoft Lync Server 2013

    Hi,
    I try to upgrade from Evaluation to full Version using:
    http://technet.microsoft.com/en-us/library/gg521005.aspx
    but after i run: msiexec.exe /fvomus server.msi EVALTOFULL=1 /qb
    i get a popup:
    "Another version of this product is already installed. installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel."
    Get-CsServerVersion :-> Microsoft Lync Server 2013 (5.0.8308.0): Evaluation license key installed.
    Any ideea?

    Hi Iulius
    As your upgrading the Licence on the Lync 2013 FE it shouldn't care about the Lync 2010 Environment. As your moving from Eval to Full Licence on 2013. I have come across the below url that might help.
    http://pei.com/2013/03/how-to-change-lync-license-from-evaluation-to-licensed/
    http://jackstromberg.com/2013/02/how-to-activate-lync-evaluation-to-licensed-version/
    I would personally go with from Lync Management Shell with Elevated Permission
    cd /
    cd /d: (Other what other drive letter)
    cd /Setup\Amd64\Setup
    msiexec.exe /fvomus Server.msi EVALTOFULL=1 /qb
    But that's just me Id rather run the command from the directory than pointing to it.
