1 Session Manager Overview Seattle IAUG Chapter Meeting

2 Agenda Session Manager continues to evolve.. Flexibility BYOD Soft Clients Endpoints SIPenablement 3 rd Party Adjuncts Centralized SIP Trunking Redundancy Trunking to deliver new possibilities

3 Session Management Avaya Session Manager (SM) Has Two Main Functions: 1. SIP Routing Element (SRE) Common, Centralized Enterprise Wide Dialplan Normalization of SIP Multi Vendor Interoperability Enterprise Wide Least Cost Routing and Time of Day Routing Alternate Routing (Around Network Failures, Congestion) Load Balancing Call Admission Control (CAC) 2. User Relationship Element (URE) Bind Users to Devices Authenticate Users, Devices, Cloud Elements Bind Users to Applications Sequence Applications For Users

4 Connection Management Connection Management Session Management

5 Session Manager Core Network Routing eliminates meshed trunk networking and support centralized applications Full Mesh N 2 N Interconnects N Separate Routing Databases No Centralized Trunking No On Net Dialing N Interconnects 1 Routing Database SIP Trunking On Net Dialing SYS Centralized SIP Applications Named Apps Sequenced Apps 3rd Party SIP Endpoints MM CM FS Named & Sequenced ApplicationsCC SIP Session Manager Avaya CS1K, Avaya CM, IP Office 3 rd Party PBX Avaya One X & 3 rd Party SIP Endpoints

12 Key New Features in Session Manager Dial Plan Transparency for SIP User does not have to dial different numbers based on the IP network connectivity status (i.e. sunny day vs. rainy day) Multi Device Access Users can be simultaneously logged into multiple SIP devices and switch between devices while on a call SIP Call Loop Elimination Prevent call loops that can consume all the SIP trunk resources VMware enablement enhancements Multiple VMware footprints and all the features in 6.3 available on VMware platform

14 Communication Manager System Settings Configure locations Configure IP Codec Set Configure IP Network Region Configure IP Node Names and IP Addresses Configure SIP Signaling Groups and Trunk Groups Configure Route Patterns Administer Uniform Dial Plan Administer Numbering Plan Administer AAR Analysis

15 Session Manager Administration Define SIP Domain and Locations Define SIP Entities for each Session Manager and Communication Manager Define Entity Links, which describe the SIP trunk parameters used by Session Manager when routing calls between SIP Entities. Define Entity Link between Session Managers Define Routing Policies and Dial Patterns which control routing between SIP Entities Define Managed Elements Define Applications/Sequences supporting SIP Users Add new SIP Users

16 How Session Manager Routes Calls Session Manager Routing Logic SIP Location Table USER AGENT Dynamic IPs Few Calls Line Level Access Network Routing Policy SIP ENTITIES Static IPs Many Calls Trunk Line Access

19 Bring Your Device using Session Manager

20 BYOD Challenges IT Compliance Who gets on? To do what? To go where? Network Capacity Can I handle multiple devices per user & high bandwidth applications? Security How can I address? Quality of Service How can I ensure business critical applications get priority?

21 Your BYOD Roadmap One X Mobile ios Supports iphones and ipads One X Lite Augments EC500 Supports Androids and iphones Requires: Communication Manager 6 Session Manager One X Mobile Full Supports Androids and iphones Requires: Client Enablement Server One X Mobile Server

22 Session Manager BYOD Setup Wireless Access User Name (Extension) Password Endpoint SM Registration User Name (Extension) Password Domain Name

23 Features: One X Mobile for SIP IOS Clients iphone and ipad Telephony via WiFi Enterprise Directory Access Call Log Standard Telephony Features Requirements: Communication Manager 6.0 or Session Manager 6.0 SIP Enablement Server 5.2 ios 4.3 or greater

24 Running Avaya one X Mobile SIP for ios for the first time 1. On the ios client screen, tap the application icon for Avaya one X Mobile SIP for ios. 2. On the End User License Agreement screen, tap Accept. 3. Tap Set up Account. The system displays the SIP Server screen. 4. Enter the following primary server details: Server: The IP address of the Avaya Aura Session Manager server to which the ios client connects. Port: For Transmission Control Protocol (TCP), enter port For Transport Layer Security (TLS), enter port TLS: For TCP, tap Off. For TLS, tap On.

25 Running Avaya one X Mobile SIP for ios for the first time 5. Tap Next. The system displays the User Details screen. 6. Enter the following user details: Extension: The extension number of the ios client. Password: The password of the extension number. Domain: The domain of the ios client. 7. Tap Next. The system displays the Configuration screen. 8. Enter the configuration URL address. The URL consists a file for user authentication having details such as, name of the customer and the expiry date of the license. 9. Tap get started. The system starts the ios client with Verifying Configuration status.

26 Other vendor SIP Softphones Always test! We ve successfully used: o 3CX o Skype o X Lite

27 BYOD Android (example) Remember that endpoints should be DevConnect certified or.

28 3 rd Party SIP Client Registers with Session Manager Provides basic telephony Application should be DevConnect certified

29 SIP Dual Mode (SIP DuM)

30 Dual Mode Rationale Dual Mode handset supports both WiFi and cellular voice network Avaya provides DuM client software for Dual Mode handset Handset in WiFi environment, DuM client registers to SM with SIP; handset not on WiFi, DuM client works as EC500 cellular One X Mobile SIP 6.2 for ios is the first Avaya DuM client for iphone CM 6.3 is required : o o Sequential forking: For one incoming call, DuM handset will receive it either on SIP client, or as EC500 cellular; but not on both. Active call handoff: Between EC500 cellular and mobile SIP client.

31 High Level Requirements ec500delay FNU Incoming call CM SIP EC500 SM PSTN INVITE 18x or 200 with DuM tag Not launched: if above 18x or 200 received Launched: 4 seconds delay, if above 18x or 200 NOT received

32 Technical Design No CM administration required Supported by CM Evolution Server only If multiple EC500 entries are administered, and DuM SIP rings, all EC500 destinations won t ring. SIP DuM can be used together with H.323/SIP dual registration, and it has no impact to SIP DuM functions. Can enable barge in tone in off pbx telephone configuration set form for security alert, while working with H.323/SIP dual registration SIP DuM can be used with SIP MDA with limitations.

33 End User Perspective 1XM SIP 6.2 for iphone supporting Call Handover from Cellular to SIP PSTN 1 On going EC500 call over public cellular network Aura Session Manager Cellular Network (CDMA/GSM) 2 User wants to handover call to SIP call over WiFi. Navigate to 1XM SIP application, and bridge on to the active appearance. 1XM SIP sends Invite Join request to CM (via SM). Aura Communication Manager 3 Aura CM joins 1XM SIP to the call, and drops EC500 call leg. 4 1XM SIP call is active over WiFi.

34 End User Perspective 1XM SIP 6.2 for iphone supporting Call Handover from SIP to Cellular 1 Active SIP call over Wi Fi connection on iphone Aura Session Manager 2 User wants to handover call to cellular voice network and taps Handover to Cellular Network button. One X Mobile initiates the Extend Call FNU, and drops the SIP call. Aura Communication Manager PSTN 3 4 Call arrives on iphone native dialer Aura CM makes an extended to cellular call to the mobile phone number (The extended call button and EC500 must be assigned for the extension in CM.) Cellular Network (CDMA/GSM) 5 User answers cellular call and continues conversation.

35 Avaya Aura Session Manager What SIP roles are played by SM? o Session Management/Routing, Registrar, Proxy How do you administer SM? o Use System Manager What enterprise functionality does SM provide? o Centralized numbering plan across multiple IP PBXs o Centralizes applications with load balancing o SIP endpoint registration True or False: SM offers up to 10 servers in an activeactive design o True
