Chapter 1: About This GuideThis guide describes how to configure a Spectralink 84-Series feature phone for connectingto Microsoft Teams using a AudioCodes Mediant SBC.This guide is intended for qualified technicians and the reader is assumed to have a basicknowledge about the Spectralink 84-Series feature phones, Microsoft Teams andAudioCodes Mediant SBC. It is also assumed, that you have an installed and functioningMicrosoft Teams, AudioCodes Mediant SBC and Spectralink 84-Series feature phone.The guide is divided into two parts: AudioCodes Mediant SBC Spectralink 84-SeriesEach part describes the general configuration and the user administration.Admin TipThe configuration steps described are only for a basic configuration to illustratethe important points when performing the integration. More advanced setupswith PSTN connectivity, Microsoft Teams hybrid environments etc. are possible,but not described here. For more information, see the Microsoft documentationsite for the latest Microsoft documentation.Setup of the MS Team and basic setup of the AudioCodes Mediant SBC arealso not covered. For more information about these tasks, see the relevantMicrosoft and AudioCodes documentation.Related DocumentationAll Spectralink documents are available at http://support.spectralink.com/.Microsoft TeamsNavigate to the Microsoft documentation site for the latestMicrosoft documentation.AudioCodes Mediant SBCNavigate to the AudioCodes Documentation Portal for thelatest AudioCodes Mediant SBC documentation.Spectralink 84-Series FeaturephonesFor more information about the feature phone, refer to the 84Series User Guide available online ink Technical BulletinsAvailable online at http://support.spectralink.com/products.Release NotesDocument that describes software changes, bugfixes,outstanding issues, and hardware compatibility considerationsfor new software releases.

Chapter 2: IntroductionFeature ListThe following features are supported:TelephonyUser experienceVoice QualityValue added Spectralink featuresSupported featuresBasic callingCall hold from 8400Call transfer BlindCall waitingCall forward on No Answer and AlwaysCentralized phone book via Active Directory and LDAPCodecs: G.711, G.722, G.729Rich APIs for third-party solutions integration InstantMessaging / Personal AlarmReal Time Location Services (RTLS) (required third partysolution)PrerequisitesThe following must be configured/installed: AudioCodes Mediant SBC with the following licenses: TEAMS (for Microsoft Teams only) Far End Users (FEU) For Microsoft Teams tenants, a Direct Route has been setup and configured with theAudioCodes Mediant SBC set up as gateway LDAP access to an Active Directory hosting the users and credentials for a user withread access.LimitationsAdmin TipThis setup requires that all users present in the AD have logged in using the MSTeam Client and configured simultaneous ringing to their 84-Series featurephone to do proper call routing.Users not in the AD will have calls routed correctly without any configuration.721-0082-000-A.docxFebruary 20216

AudioCodes Mediant SBC and Spectralink 84-Series Interoperability GuideNoteWith the setup in this guide, it is not possible to assign the same telephonenumber to both a Microsoft Teams Client and an 84-Series feature phonesimultaneously.For routing purposes, it is recommended, that the telephone numbers assignedto 84-Series feature phone are kept in a separate range.Integration SequenceThe basic 84-Series feature phone and AudioCodes Mediant SBC integration consists of thefollowing steps:1Create a SIP InterfaceFor more information, see Creating SIP Interface.2Create a Media RealmFor more information, see Creating a Media Realm.3Create an allowed Audio Coders GroupsFor more information, see Creating an allowed Audio Coders Group.4Create Message Manipulationfor more information, see Creating a Message Manipulation.5Create an Inbound Manipulationfor more information see Creating an Inbound Manipulation.6Create an IP ProfileFor more information see Creating an IP Profile.7Create an IP GroupFor more information, see Creating an IP Group.8Create ClassificationsFor more information, see Creating Classifications.9Create IP-to-IP routing rulesFor more information, see Creating IP-to-IP routing rules.Admin TipAs MS Teams requires all phone numbers to be in E.164 format, it is required totransform any other phone number format into E.164.This guide will keep phone numbers in E.164 format where possible and convertuser dialed numbers before processing.For more information about creating phone numbers in E.164 format, -A.docxFebruary 20217

AudioCodes Mediant SBC and Spectralink 84-Series Interoperability GuideTo facilitate that users with both an 84-Series feature phone and a MS Teams Client canreceive calls on both endpoints, all MS Teams Clients must be configured for SimultaneousRinging on the 84-Series feature phone. For more information about Simultaneous Ringing,see MS Teams Client documentation.Admin TipUnfortunately, setting the user’s own phone number as the destination of theSimultaneous Ringing will cause MS Teams to not route the call to the 84Series feature phone. A possible solution is to enter the local number with afake E.164 prefix and then transform to the correct prefix in the AudioCodesMediant SBC.It is recommended to use an unused E.164prefix, e.g. 999.When a call originates from an 84-Series feature phone, the AudioCodes Mediant SBC willneed to know if the call should be routed either: To a MS Team Client (and possibly also a 84-Series feature phone via SimultaneousRinging) Directly to an 84-Series feature phone.Therefore, the AudioCodes Mediant SBC will be configured to do a LDAP look-up in theActive Directory of the user of the destination number to be able to decide where to route thecall.Example EnvironmentThe detailed configuration steps in the next sections assume the following exampleenvironment: All users are homed the MS Teams environment Azure AD Domain Services is configured and has Secure LDAP enabled E.164 numbers for Teams are in the 1425100109x range E.164 numbers for 84-Series feature phones are in the 457628119x range AudioCodes Mediant SBC with IP address 172.29.198.4 84-Series feature phones with the IP address 172.29.194.* Fake E.164 routing prefix is 999721-0082-000-A.docxFebruary 20218
