10G.1A India WFH Users: Extend and Connect Architecture

Regulatory Context

Why Extend and Connect is Used in India:

India's Department of Telecommunications (DoT) and TRAI regulations prohibit toll bypass - routing PSTN calls over internet to avoid telecom charges. For Work-From-Home (WFH) users in India, using a softphone to make/receive PSTN calls from home could violate these regulations because:

  1. Toll Bypass Concern: Softphone call from Mumbai user's home in Pune could bypass Mumbai telecom circle
  2. OSP Regulations: Other Service Provider guidelines require PSTN calls to egress from registered locations
  3. Compliance Risk: Organizations face penalties for telecom regulation violations

Extend and Connect (CTI Remote Device) Solution:

|  Audio NEVER traverses internet. PSTN call routes through proper          |
|  telecom circles. Only SIGNALING (call control) goes to Jabber.           |
|  This ensures DoT/TRAI compliance for WFH users.                          |

Webex Calling Configuration for India WFH

Option A: Zone-Based Routing (Recommended)

WEBEX CONTROL HUB CONFIGURATION
===============================================================

1. Verify Zone Configuration (from Chapter 2):
----------------------------------------------
   Zones already configured:
   * Zone-Mumbai-Circle -> LGW: lgw-mumbai-01/02
   * Zone-TamilNadu-Circle -> LGW: lgw-chennai-01/02
   * Zone-Karnataka-Circle -> LGW: lgw-bangalore-01
   * Zone-Delhi-Circle -> LGW: lgw-delhi-01

2. Assign WFH Users to Correct Zone:
------------------------------------
   Control Hub > Calling > Locations > [Location] > Zones

   User: ramesh.kumar@abhavtech.com
   Home Location: Pune (Maharashtra)
   Telecom Circle: Mumbai
   Assigned Zone: Zone-Mumbai-Circle

   Result: All PSTN calls route via Mumbai LGW regardless
           of user's physical location (Pune, home, etc.)

3. Trusted Network Edge (Optional):
-----------------------------------
   If user connects from office:
   * Webex detects office network
   * Uses optimized media path

   If user connects from home:
   * Webex uses cloud media
   * PSTN still routes via assigned Zone's LGW

Option B: Simultaneous Ring (Extend & Connect Equivalent)

SIMULTANEOUS RING CONFIGURATION
===============================================================

Control Hub > Users > [User] > Calling > Call Handling

1. Call Forwarding & Simultaneous Ring:
---------------------------------------
   [x] Enable Simultaneous Ring

   Ring these numbers when my line is called:
   +---------------------------------------------------------+
   | Number                    Ring Delay    Answer Confirm  |
   | ------------------------------------------------------- |
   | +91-98765-43210 (Mobile)  0 seconds     [x] Yes          |
   |                                                         |
   | [+ Add another number]                                  |
   +---------------------------------------------------------+

   Answer Confirm: Prevents voicemail pickup
   Ring Delay: 0 = immediate, matches Webex App ring

2. Webex App Settings:
----------------------
   User's Webex App still rings
   User can answer on:
   * Webex App (audio via WebRTC) - OR -
   * Mobile phone (audio via PSTN)

   Once answered on mobile:
   * Webex App shows active call
   * User can control: Hold, Transfer, Conference
   * Audio remains on mobile

3. Outbound Calls:
------------------
   From Webex App: Uses Webex Calling (Zone routing)
   From Mobile: Uses mobile carrier (separate)

   For outbound from Webex App to use mobile audio:
   Configure "Call Me" or "Dial via Office" feature

Jabber-Specific Attribute Preservation

PRESERVING JABBER USER DATA DURING MIGRATION
=================================================================

Store these in AD extensionAttributes for reference during migration:

extensionAttribute1 = CUCM Extension (e.g., "1234")
extensionAttribute2 = CUCM Device Name (e.g., "SEP001122334455")
extensionAttribute3 = Jabber Username (if different from UPN)
extensionAttribute4 = Unity Mailbox (e.g., "mailbox_1234")
extensionAttribute5 = MRA Status (e.g., "MRA-Enabled")

Purpose:
* Reference during Webex provisioning
* Audit trail for migration
* Rollback information if needed
* License assignment automation

Certificate Migration Notes

CERTIFICATE CONSIDERATIONS
=================================================================

ON-PREMISES CERTIFICATES (No Migration Required):
-------------------------------------------------
* CUCM certificates -> Not needed after decommission
* IM&P certificates -> Not needed after decommission
* Expressway certificates -> Not needed after decommission
* Unity certificates -> Not needed after decommission

These remain valid during coexistence, then become irrelevant.

IDENTITY PROVIDER CERTIFICATES (Continue to Manage):
----------------------------------------------------
* IdP signing certificate -> Used by both Jabber SSO and Webex SSO
* Set calendar reminder for IdP certificate renewal
* When IdP cert renews, update in Webex Control Hub

WEBEX CLOUD CERTIFICATES (Managed by Cisco):
--------------------------------------------
* Webex service certificates -> Cisco managed
* No customer action required
* Trust chain pre-installed in Webex App

Firewall Rules to ADD (Webex)

WEBEX CLOUD FIREWALL REQUIREMENTS
=================================================================

Webex requires OUTBOUND access only (no inbound rules needed):

Destination                         Ports       Protocol
----------------------------------------------------------------
*.webex.com                         443         TCP (HTTPS)
*.wbx2.com                          443         TCP (HTTPS)
*.ciscospark.com                    443         TCP (HTTPS)
*.webexcontent.com                  443         TCP (HTTPS)

Media (if not using HTTPS media):
*.webex.com                         5004        UDP
*.wbx2.com                          5004        UDP
Media IP ranges                     33434-33598 UDP

Note: Webex App can operate with HTTPS-only (port 443).
      UDP ports improve media quality but are optional.

10G.16 Client Deployment Strategy

Deployment Phases

WEBEX APP DEPLOYMENT STRATEGY
=================================================================

PHASE 1: Parallel Deployment (Week 1-2)
---------------------------------------
Goal: Get Webex App on all devices while Jabber still works

[ ] Deploy Webex App via:
  * SCCM/Intune (Windows)
  * JAMF (Mac)
  * MDM (Mobile)

[ ] Users have BOTH apps installed:
  * Jabber: Still connected to CUCM (primary for calls)
  * Webex: Connected to Webex Cloud (for familiarization)

[ ] Communicate to users:
  "Webex App is installed. Feel free to explore, but 
   continue using Jabber for phone calls until notified."

PHASE 2: User Training (Week 2-3)
---------------------------------
Goal: Ensure users are comfortable with Webex App

[ ] Conduct training sessions:
  * Online webinars (record for later viewing)
  * Quick reference guides
  * FAQs and comparison guides

[ ] Training topics:
  * Making and receiving calls
  * Using messaging
  * Finding contacts
  * Voicemail access
  * Settings and preferences

PHASE 3: Migration Cutover (Week 4+)
------------------------------------
Goal: Move users from CUCM/Jabber to Webex Calling

[ ] Migrate users batch-by-batch
[ ] On cutover:
  * User's phone number moves to Webex
  * Webex App becomes PRIMARY
  * Jabber STOPS WORKING for calls

[ ] Communicate to users:
  "Your phone service has moved to Webex. 
   Please use Webex App for all calls. 
   Jabber will no longer work for phone calls."

PHASE 4: Jabber Removal (Week 6+)
---------------------------------
Goal: Clean up old clients

[ ] Wait 2+ weeks after last user migration
[ ] Remove Jabber via:
  * SCCM uninstall task
  * Intune uninstall
  * JAMF removal policy
  * MDM app removal

[ ] Users should only have Webex App

10G.17 User Migration Procedures

Part 7: Layer 5 - IM & Presence Migration

10G.18 CUPS to Webex Messaging

IM Migration Considerations

IM & PRESENCE MIGRATION CONSIDERATIONS
=================================================================

QUESTION: Do your users rely on IM & Presence?

Assess IM Usage:
----------------
[ ] Heavy IM usage (primary communication)
[ ] Moderate IM usage (supplement to email)
[ ] Light IM usage (occasional)
[ ] No IM usage (phone only)

If Heavy/Moderate:
------------------
* Plan for messaging migration
* Communicate change to users
* Consider chat history requirements

If Light/None:
--------------
* Migration is straightforward
* Webex Messaging available immediately
* No special planning needed

CHAT HISTORY:
-------------
[!]️ Jabber/CUPS chat history does NOT migrate to Webex

Options:
1. Start fresh in Webex (recommended)
   * Clean slate
   * No technical complexity
   * Users adapt quickly

2. Archive old messages
   * Export from CUPS database
   * Provide to users as archive
   * Does NOT import to Webex

Recommendation: Start fresh. Most organizations find that
historical IM messages have limited value.

Feature Mapping

CUPS/Jabber IM Feature Webex Messaging Equivalent
1:1 Chat Direct Messages
Group Chat Group Spaces
Persistent Chat Rooms (MUC) Spaces (persistent)
File Transfer File Sharing in Spaces
Presence Webex Presence (automatic)
XMPP Federation Webex Connect (external)

10G.19 Presence Federation

Federation Comparison

Aspect Jabber/CUPS Webex
Internal presence IM&P server Webex Cloud
External federation XMPP federation Webex Connect
Microsoft Teams N/A or complex Native integration
Cisco partners XMPP Webex B2B

Presence Behavior After Migration

PRESENCE BEHAVIOR IN WEBEX
=================================================================

Automatic Presence:
-------------------
Webex automatically shows presence based on:
* Calendar status (in meeting = busy)
* Call status (on call = busy)
* Focus time (DND)
* User-set status

Status Synchronization:
-----------------------
Presence syncs across all Webex surfaces:
* Webex App (desktop)
* Webex App (mobile)
* Webex Meetings
* Microsoft Teams (if integrated)

User-Configurable Status:
-------------------------
* Available
* Busy
* Do Not Disturb
* Away
* Custom status message (e.g., "Working remotely")
* Scheduled status (e.g., DND from 6 PM - 8 AM)

10G.20 Chat History Considerations

Chat History Decision Matrix

Scenario Recommendation Action
Compliance requirement Archive Export CUPS DB, store per retention policy
Users request history Inform Explain history doesn't migrate, start fresh
Legal hold Archive Export and retain per legal requirements
No requirement Skip Start fresh in Webex

CUPS Chat Export (If Required)

CUPS CHAT HISTORY EXPORT (For Archival Only)
=================================================================

Note: This is for ARCHIVAL purposes. Chat history cannot be
      imported into Webex Messaging.

Step 1: Access CUPS Database
----------------------------
Connect to IM&P Publisher via CLI or Informix tools

Step 2: Export Messages
-----------------------
-- SQL to export messages (simplified)
SELECT 
    sender_jid,
    recipient_jid,
    message_text,
    timestamp
FROM tc_messages
WHERE timestamp > '2024-01-01'
ORDER BY timestamp;

Step 3: Format for Archive
--------------------------
Export to CSV or XML format
Store in compliance archive system
Document retention period

Step 4: Communicate to Users
----------------------------
"Your chat history from Jabber has been archived. 
 It will not appear in Webex. New conversations in 
 Webex will be retained according to company policy."

Part 8: Layer 6 - Voice Services Migration

10G.21 CUCM to Webex Calling

Voice Migration Overview

The voice services migration is covered extensively in: - Chapter 7: Migration Execution (detailed procedures) - Appendix 10E: Identity & Directory (user provisioning)

Key aspects specific to Jabber users:

JABBER USER VOICE MIGRATION
=================================================================

Jabber Phone Features -> Webex Calling Features:

CUCM Feature              Webex Calling Feature
----------------------------------------------------------------
Softphone (CSF device)    Webex App (native calling)
Desk phone control (CTI)  Webex App desk phone control
Extension Mobility        Webex App (login anywhere)
Single Number Reach       Webex multi-device ringing
Mobile Connect            Webex App mobile
Cisco Jabber for VDI      Webex App for VDI

Migration Impact:
-----------------
* CSF device deleted from CUCM
* User's DN moves to Webex Calling
* Calling features configured in Webex
* Jabber stops working for calls immediately
* Webex App becomes the calling client

10G.22 Voicemail Migration (Unity to Webex)

Voicemail Migration Strategy

VOICEMAIL MIGRATION: UNITY CONNECTION -> WEBEX
=================================================================

OPTION 1: Fresh Start (Recommended)
-----------------------------------
* Users get new Webex Voicemail mailbox
* Old Unity messages remain accessible during coexistence
* Users record new greetings in Webex
* After coexistence, Unity decommissioned

Pros:
OK Simple migration
OK No technical complexity
OK Clean start

Cons:
X Old messages not migrated
X Users must re-record greetings

OPTION 2: Message Export (Complex)
----------------------------------
* Export messages from Unity as WAV files
* Provide to users as archive
* Messages do NOT import to Webex Voicemail

Pros:
OK Users have access to old messages

Cons:
X Time-consuming
X Still need new Webex setup
X Messages not integrated

RECOMMENDATION: Fresh Start
---------------------------
Most voicemail messages have short-term value. 
Users adapt quickly to new mailbox.

USER COMMUNICATION:
-------------------
"Your voicemail has moved to Webex. 
 Please set up your new voicemail PIN:
 1. Dial *86 from your phone
 2. Follow prompts to set PIN and record greeting

 Old messages in Unity remain accessible at [pilot number]
 for 30 days."
