Objective
Meant to serve as an end-to-end guide for provisioning Yealink and Poly phones.
User Context
-
Provisioning Flowchart for Polycom and Yealink
Procedure
Is it a device we support?
Is it on the recommended firmware?
NOTE: Skip if it's a new customer and the phone was purchased from us
For Implementations:
- Ensure that all phones' MAC addresses are added to the Inventory.
- Export list of phones and configure lines as necessary.
- Assign custom configs if necessary.
For Support:
- Add the Phone to the Domain's Inventory and configure it on Snapbuilder.
- Hit Save and re-sync.
NOTE: It would be a good idea to add notes to the phone, so we know who it points to on NDP
Did it provision as expected?
End.
Confirm if the device is hitting the redirect
Is it a Yealink RPS or a Polycom?
Is the device "Bound" on RPS and pointing to a server?
Reboot and/or factory reset.
Did it work?
End.
Access the phone's GUI and use the following credentials on the auto provisioning tab (use this wui.http_enable="1" and FR)
NOTE: wui.https_enable="1" to access GUI if it already hit NDP 2739
- Provisioning url: https://prov.vipvoice.io/cfg/ or https://endpoints.crexendovip.com/cfg
- Username: phonevip
- Password: CFUj3wBTeJ DNS: 8.8.8.8, 8.8..4.4 or 1.1.1.1, 1.0.0.1
IF THE DEVICE REACHES NDP, double-check assigned lines for fat-fingering, then re-add/reassign the phone to the user. You will need to enable a global one-time password for a factory reset, then factory reset again.
Did it work?
End.
Refer to the VOIPmon guide.
- Check the tickbox beside the MAC address
- Check if the IP Address is the same as what is displayed on RPS
- Factory reset.
- In the VIP Portal, go to Inventory
- Go to the Phone Hardware tab
- Click Allow Global Credentials (Key icon)
