Telstra DoT Migration Guideline for Partners & End Users
Overview
This guideline explains the recommended process to migrate from Telstra Digital Office Technology (DoT) to CommsChannel NBN and Yeastar Cloud UC services. The sequence of steps is designed to prevent downtime to internet or telephony services and ensure inbound calls continue to reach the business during migration.
This document applies to:
Partners performing migrations
End users preparing for migration
Sites using Telstra DoT with Yealink IP handsets
Key Principles (Partner Responsibilities)
Partners own the entire customer-facing process including customer communication, requirements gathering, ordering information collection, and liaison with CommsChannel for provisioning and migration activities.
Partners must ensure Telstra services are not cancelled until migration is confirmed complete
Partners must deploy and test new telephony using a temporary DID first
Partners must enable call forwarding from the main Telstra number before porting
Yealink handsets can be reused but must not be factory reset until instructed by CommsChannel
Skipping steps or changing the order can result in service outages.
Migration Options
Partner responsibility: Partners are responsible for configuring and managing all routers, switches, and customer premises equipment (CPE) at the site. Partners must also provide 100% complete and accurate service information to CommsChannel, in line with standard provisioning processes, to enable PBX creation and NBN provisioning.
Option 1 – Parallel NBN Installation (Lowest Risk)
A new NBN service is installed alongside the existing Telstra service. This is the safest method and allows full testing before cutover.
Option 2 – NBN Transfer / Churn (Lower Cost)
The existing Telstra NBN service is transferred to CommsChannel using the AVC ID. This avoids a new installation fee but requires strict sequencing.
Standard Migration Workflow
Step 1 – Identify the Main Business Number
Confirm the primary advertised business number. This number will be forwarded and ported as part of the migration.
Step 2 – Prepare Yeastar Cloud UC
CommsChannel will:
Create the Yeastar tenancy
Configure users and extensions
Assign a temporary DID
Add Yealink handset MAC addresses to the system
Step 3 – Test Using the Temporary DID
Partners/end users must:
Place inbound and outbound test calls
Confirm call quality and routing
No handset resets should occur at this stage.
Step 4 – Enable Call Forwarding from Telstra
Forward the main Telstra business number to the temporary DID. Verify calls route correctly to the new system.
Step 5 – Submit Number Port
CommsChannel submits the port request. Telstra services must remain active during this period.
Step 6 – Validate Port Completion
After porting:
Test inbound calls from multiple networks
Confirm correct call routing
Step 7 – Finalise Internet Cutover
Depending on the chosen option:
Option 1: Switch production traffic to the new NBN service.
Option 2: Perform NBN churn using the verified AVC ID and confirm connectivity.
Step 8 – Cancel Old Telstra Services
Only after successful validation should Telstra services be cancelled.
Yealink Handset Reuse & Reset Procedure
Important Warning
Do NOT factory reset phones until CommsChannel confirms provisioning is ready. Early resets can leave phones unregistered and disrupt business operations.
Reset Steps (When Instructed)
Ensure the phone is powered on
Press and hold the OK button for ~10 seconds
Confirm the factory reset prompt
Allow the phone to reboot and auto-provision
Wait for extension registration confirmation
If the phone does not register within 5 minutes, contact CommsChannel support.
Static IP Edge Case
If the site uses a static IP:
Identify any VPNs or firewall rules dependent on it
Reconfigure these services before internet cutover
Troubleshooting & Escalation
If any step fails or call routing is incorrect:
Stop the migration at the current stage
Contact CommsChannel support immediately
Provide timestamps and test call details
Summary Checklist
Main number identified
Temporary DID active and tested
Call forwarding enabled
Port submitted and validated
Internet cutover completed
Yealink phones reset only when instructed
Telstra services cancelled after confirmation
Following this process ensures a smooth, outage-free migration.
