SfB - postdeployment headache. RRS feed

  • Question

  • Greetings everyone,

    we are in the process of deployment of Skype for Businnes desk phones (namely Polycom CX600). We have Survivable Branch Appliance (SBA) on-site and SfB server is in headquarters. We have bunch of problems I'm not able to resolve on my

    own, that's why I'd like to ask you for help.

    1) On some phones, when call is made, only 3 digits number is displayed instead of  E.164 format number. Therefore, contact in Active Directory isn't found and callee doesn't know who's the caller. Could this be related to poorly

    designed dial plan? Does dial-plan apply even when calling in one site? We have two dialplans created by the implementor - user dial plan and site dial plan. Which one takes the precedence?

    2) CX600 phones are tethered to desktop PCs. I have witnessed, that caller can't hear progress tone when SfB application isn't running on user's PC. I have no clue what could be the reason.

    3) There is probably some kind of twisted firmware update sitting on the server and is downloaded by phones when they restart. Result is, that screen gets shifted about 30 pixels to upper left corner and some part on the left and some

    part of the top part of the screen are hidden. Hard reset usually helps. Did it ever happen to you?

    4) From time to time, we experience difficulties when phone tries to register itself. It it took me half a day to make phone register itself - he couldn't register when tethered with pc, re-creation of SfB user account didn't help as

    well. Only manual logon via pin code allowed me to register the phone, after several attempts, though.

    Thank you, best regards,
    S.

  • Hello all,

    it's me again. Issue number 2 has been solved - I have found out that SBA doesn't update itself in terms of Lync updates. I updated my SBA with cumulative patches and issue number 2 is resolved.

    When  it comes to issue number 1, more experienced colleague of mine confirmed that I have to fine-tune my dialplans, which are quite messy at the moment.

    I'll try to resolve #3 and #4 during planned outage of our environment. 

    For now, thank you all. 

    Take care,

  • 1. If you have configured the user for enterprise voice or a common area phone. All dialed numbers will normalized through the configured Dialplan. You can test this through the SFB controlpanel.

    If you have some phones, it could take up some time for sync the phones, but you can restart the phone to use the new configuration. You should have a rule for changing 3digit numbers to the complete E.164 phone number.

    2. The phone works without pc, so you should here something. Depending of you AD country settings the dialtone will also change.

    3. No, you should use always the latest updates.

    4. You should check you DHCP settings. maybe something is different configured. Do you use Vlan configuration?

    Maybe you don't have setup the correct time server settings?

    1. Best option would be create a separate dial plan for your SBA Site and normalization rules under dial plan.make sure those are resolved correctly as like your central site.

    2.If your phone does not work independently then something wrong with voice VLAN, take phone logs or Port mirroring logs when you are testing and see whats going wrong.

    3. Make sure phone has latest updates the one which your Lync server approved. otherwise you see wired issues.

    4. I agree with Holger that please check your DHCP and Time server settigns to figure out the issue.

  • 1: Dial plan check can be done from the Lync Control panel to verify  how it changes the number 

    2 : Once the phone is tethered and  Certificate is downloaded we do not  need the computer to be connected /Tethered as it should be able to login without the computer after that. 

    3: Is that happening with  all the devices , maybe  you should replace that particular device?

    4:When tethered with PC , you should be getting a prompt to enter the credential for  your phone to download the certificates and provisioning details , did you try with different PC. Reset the phone and try again.

  • Hello Holger,

    thank you for your swift reply. Some additional questions arose on my site:

    1) I assume Dial plan influences called numbers, not calling. Given that dial-plan will be adjusted to our needs, how does this relate to our callers' numbers? Problem is, that callee sees 3-digit caller's number. I'm afraid dial plan won't help me therefore.

    2) Okay, this deserves more testing, I need to ensure that the problem have all the users with CX600 on the table or only particular ones. Is there a possibility to check the settings of call-progress tone in AD?

    3) Okay, I'm gonna deep dive into firmware available on the server. At the time, I'm not aware of any CX600 update that would cause that behavior.

    4) Yes, we use VLAN configuration and that particular phone was connected to switchport with proper voice and access vlan assignment. I'm gonna check DHCP and make further testing with more phones on more switchports.

    There are public holidays in our country for the next few days. As soon as I get more relevant data, I'll get back to you.

    Thank you!

  • Hello RajuKB,

    thank you for the reply. Again, bullet by bullet:

    1) Yes, we have site dial-plan and user dial plan in addition to that. I believe site dial-plan is applied to the whole site and user dial-plan is applied to particular users (that's for sure). Question is - what happens when there are two dial-plans applied? I.e. one for whole site and one for each particular user. Which one takes a precedence?

    2) Thank you for the opinion, I agree, further testing is necessary.

    3) Okay, I'm going to get more familiar with the updates available.

    4) DHCP server will be checked.

    Thank you for the website links, I'm already going through it.

    I'll get in touch with you when some progress is made.

    Take care.

  • Hi Akampa,

    thank for the valuable input, more testing will be done as your post suggests.

  • For the question 1, when there is Site dial plan and User dial plan, whn you assign user dialplan to user User dialplan will take precedence. 

    If you apply automatic, then  global dialplan takes precedence.

  • Hello all,

    it's me again. Unfortunately, issue #2 (cannot hear progress tone when SkypeForBusiness app on client isn't running) hasn't been fully solved, I experience these issues again - namely when calling from analog PBX to Lync world (via mediant gateway).
