Review call flows, extension needs, site connectivity and existing numbers before selecting a deployment. Identify the people responsible for carrier services and emergency-calling decisions early in the project.
DeliverableTelephony requirements and dependency register.
Install and configure an approved IP PBX for the agreed organization and call workflows. Validate endpoint registration, routing and administration with the customer's nominated owner before handover.
DeliverablePBX configuration and acceptance record.
Configure the agreed hosted calling platform, users and supported endpoints. Coordinate subscription ownership and carrier requirements so the service can be managed independently after implementation.
DeliverableCloud calling configuration and user register.
Connect supported carrier SIP services to the approved telephony platform. Confirm provider settings, number ownership and routing, testing inbound and outbound calls before transition.
DeliverableSIP integration and call test record.
Deploy approved desk phones with the required network and power connections. Assign extensions, verify common calling functions and label assets so support teams can identify each installed endpoint.
DeliverableHandset register and functional checks.
Design extension allocation and dialing conventions for users, departments and sites. Keep the scheme understandable and expandable while documenting public-number routing and special-use devices.
DeliverableNumbering plan and extension directory.
Configure menus and call-routing options around the customer's approved wording and business structure. Test invalid selections, timeout paths and after-hours behaviour to avoid calls reaching a dead end.
DeliverableCall menu map and test evidence.
Implement approved queue membership, distribution and overflow rules. Confirm the operational owner and reporting needs, testing busy and unanswered scenarios before the queue enters service.
DeliverableQueue configuration and scenario checks.
Set up groups that route incoming calls to the intended team. Agree simultaneous or sequential behaviour and fallback handling so a group remains usable when staff are unavailable.
DeliverableRing-group schedule and call-flow tests.
Configure individual and shared voicemail according to approved business requirements. Validate notifications and access methods while keeping retention and message ownership decisions with the customer.
DeliverableMailbox setup and user instructions.
Configure supported desktop or mobile calling clients for authorized users. Check microphones, headsets and representative connectivity conditions, explaining limitations outside the managed office network.
DeliverableSoftphone onboarding and test checklist.
Coordinate extensions and routing across approved locations or systems. Review WAN dependencies, number plans and support ownership so a site change does not unexpectedly affect the wider calling environment.
DeliverableInter-site call plan and validation report.
Review switch power, addressing and quality-of-service dependencies for the proposed voice environment. Identify physical or configuration prerequisites before phones are installed and service is migrated.
DeliverableReadiness checklist and remediation priorities.
Configure supported recording features only where the customer has approved the purpose and operating policy. Clarify access, storage and retention requirements without providing legal conclusions about consent.
DeliverableRecording configuration and ownership record.
Implement time-based call handling using an approved schedule and exception dates. Test transitions between open, closed and holiday behaviour so callers receive the intended options.
DeliverableRouting schedule and scenario test record.
Coordinate the technical transition around a carrier-managed number port. Track prerequisites and testing responsibilities while leaving carrier acceptance and timing subject to the provider's confirmation.
DeliverablePort checklist and transition communication plan.
Connect supported directories or provision approved contact information to calling devices. Confirm data ownership and update procedures so users can locate colleagues without maintaining conflicting lists.
DeliverableDirectory mapping and synchronization checks.
Identify platform and provider prerequisites for emergency calling, including location records and user communication. Coordinate with the responsible parties and use only approved test procedures for the deployment.
DeliverableResponsibility record and provider confirmation checklist.
Show users and nominated administrators the calling features included in their deployment. Focus on daily tasks, transfer behaviour and support routes using the organization's actual call-flow design.
DeliverableUser guides and administrator walkthrough.
Test agreed inbound, outbound, transfer, queue and failure scenarios across representative endpoints. Record provider dependencies and unresolved exceptions before the customer accepts the system.
DeliverableCommissioning report and final call-flow diagrams.
