Implementation & Deployment¶

This chapter provides step-by-step procedures for implementing Webex Calling and Contact Center, including Control Hub configuration, PSTN setup, and ready-to-use configuration templates.

Chapter Overview¶

Sections¶

6.1 Control Hub Setup ->
Complete implementation guide including Control Hub initial setup, PSTN configuration (Local Gateway and CCPP), and configuration templates for India Zone/Edge, LGW CUBE, and route groups

6.2 PSTN Configuration ->
PSTN connectivity setup by region, trunk configuration, route group assignments, emergency services

6.3 Configuration Templates ->
Ready-to-use templates for India LGW CUBE, Zone/Edge, Control Hub settings, dial plan configuration

Implementation Phases¶

Phase 1: Foundation (Weeks 1-2)¶

Control Hub Setup: - [ ] Create organization and activate trial/production licenses - [ ] Configure calling regions (APAC, UK, EU, US) - [ ] Create Webex locations matching physical sites - [ ] Configure number management and DID ranges

Directory Integration: - [ ] Azure AD / LDAP integration - [ ] User provisioning and synchronization - [ ] Group assignments and access policies

Phase 2: PSTN Integration (Weeks 3-4)¶

India - Local Gateway Deployment: - [ ] Deploy ISR 4K routers per telecom circle - [ ] Configure CUBE for SIP trunking to Tata/Airtel - [ ] Deploy Webex Zone and Trusted Network Edge - [ ] Configure trunk groups and route lists - [ ] Test PSTN connectivity and toll bypass compliance

EMEA/Americas - Cloud Connected PSTN: - [ ] Order CCPP service from IntelePeer (UK/EU/US) - [ ] Configure trunk groups in Control Hub - [ ] Port existing DID numbers - [ ] Test PSTN connectivity

Phase 3: Features & Policies (Weeks 5-6)¶

User Features: - [ ] Configure voicemail settings - [ ] Enable call forwarding and simultaneous ring - [ ] Set up hunt groups and call queues - [ ] Configure paging groups - [ ] Enable mobile integration (Webex Go)

Call Policies: - [ ] Outbound calling permissions - [ ] International calling restrictions - [ ] Call recording policies (where applicable) - [ ] Emergency services configuration

India-Specific Implementation¶

Local Gateway Deployment (Per Telecom Circle)¶

Hardware Requirements:

Circle	Router Model	Licenses	PSTN Provider
Mumbai	ISR 4451-X	CUBE + DNA	Tata/Airtel
Tamil Nadu	ISR 4351	CUBE + DNA	Tata
Karnataka	ISR 4331	CUBE + DNA	Tata
Delhi	ISR 4331	CUBE + DNA	Tata
UP West	ISR 4331	CUBE + DNA	Tata
AP/Telangana	ISR 4331	CUBE + DNA	Tata

Zone/Edge Components: - Webex Zone: Virtual appliance (OVA) deployed on-premises - Trusted Network Edge: Public IP for PSTN egress - SIP Trunks: To PSTN provider per circle

Configuration Template Example¶

EMEA/Americas Implementation¶

Cloud Connected PSTN Setup¶

Configuration Steps:

Order CCPP Service
Select regional provider (IntelePeer UK/EU/US)
Specify DID quantities and number types
Request E911/emergency services provisioning
Control Hub Configuration
Add CCPP trunk group
Assign trunk to locations
Configure outbound routing
Number Porting (if migrating existing DIDs)
Submit LOA (Letter of Authorization)
Schedule port date
Test ported numbers before cutover

Configuration Templates¶

Included Templates¶

Appendix H contains ready-to-use templates for:

India LGW CUBE configuration (per ISR model)
Webex Zone deployment guide
Control Hub location settings
Route group and route list configuration
Emergency services configuration (India/UK/EU/US)
Dial plan templates

Implementation Validation¶

Before proceeding to migration:

Control Hub organization fully configured
All Webex locations created and validated
PSTN connectivity tested (inbound and outbound calls)
India toll bypass compliance validated
Emergency services tested
User features tested
Policies and restrictions validated

Next Steps¶

Review Migration Execution for cutover procedures
Review Appendix H for detailed configuration templates
Begin pilot user testing before full migration
