As of today: Cloud PBX with PSTN Calling doesn't support Common Area Phone
Scenario:
Target goal is to convert existing Polycom SoundPoint IP, Polycom VVX phone to Common Area Phone without need to purchase additional phone devices.
Solution:
- Check if Skype for Business Server (Lync) is enabled for PIN authentication:
Get-CsWebServiceConfiguration | fl Identity, UsePinAuth, UseCertificateAuth
- The DHCP 043/120 options which provide the ability to support PIN authentication (will be strict requirement for Common Area Phone accounts to authenticate via TLS-DSK)
- The DHCP 004/042 options (Time Server). Although the time server location will provide the accurate time required to perform authentication and registration processes the phone will display the time in GMT by default. To show the correct local time on the phone’s display the standard time offset DHCP 002 option (Time Offset, optional) can be used.
Check your DHCP options presence on your DHCP server:
Get-DhcpServerv4OptionValue -ComputerName yourdhcpserver.com -ScopeId 172.20.0.0 -All | ft OptionID,Name,Value,VendorClass
- You can use NTP SRV DNS record as an alternative to Time Server DHCP options
_ntp._udp.<SIP domain> pointed to NTP server; - PIN authentication is only supported for internal networks which can contact the internal web services on a Lync Front End server internally;
- PIN Authentication doesn't work via Edge Server;
- Phone ability to sign in via PIN authentication.
As you probably noticed everything is spinning around phone and network support for PIN authentication:
- PIN Authentication requires minimum 4.1.2 firmware which applies to Polycom VVX 300, 310, 400, 410, 500, 600, 1500;
- PIN Authentication requires minimum 4.1.1 firmware which applies to SoundPoint IP 321, 331, 335, 450, 550, 560, and 650, SoundStation IP 5000 and SoundStation Duo (90757 Added support for PIN authentication). Latest one is 4.1.1 AA firmware (August 2015)
Recommended settings for Polycom/Soundpoint IP models acting as Common Area Phones
If we are in the process of deploying a phone in a common area we will most likely want to disable some of the default features (it is not strict prerequisite but rather recommendation), functions and physical ports on the VVX/Soundpoint IP.
Put these parameters into your XML configuration file that will be uploaded to the phone via Polycom provisioning server or via the WebUI of the phone.
1. Disable physical ports on the phone such as the USB and PC ports:
2. Disable the speakerphone hard key and speakerphone functionality:
3. Disable the Home hard key to limit access to menus such as the Settings menu:
4. Remove and/or limit soft key functions (New Call, Sign Out, etc.):
5. Disable additional features:
device.set = "1"
device.net.etherModePC = Disabled
device.auxPort.enable.set = "1"
device.auxPort.enable = "0"
feature.usb.power.enabled = "0"
up.handsfreeMode = "0"
key.26.function.prim = null
feature.enhancedFeatureKeys.enabled = "1"
softkey.feature.basicCallmanagement.redundant = "0"
softkey.feature.forward = "0"
softkey.feature.simplifiedSignIn = "0"
softkey.feature.mystatus = "0"
softkey.feature.buddies = "0"
softkey.feature.newcall = "0"
softkey.feature.doNotDisturb = "0"
video.enable = "0"
diags.pcap.enabled = "0"
feature.callRecording.enabled = "0"
feature.pictureFrame.enabled = "0"
dir.local.readonly = "1"
6. Force phone device to use PIN authentication
Common Area Phone object provisioning on Skype for Business Server (Lync) is very standard process:
You can also use UI based tool called "Lync Common Area Phone Management" tool. The tool was successfully tested with Skype for Business Server 2015.
Another cool feature introduced with Common Area Phone called Hot-Desking. You can set up Common Area Phones as hot-desk phones. With hot-desk phones, users can log on to their own user account, and, after they are logged on, use Skype for Business Server features and their own user profile setting.
Per my understanding phones of other vendors may behave like Common Area Phones. Just check if they support PIN authentication.
