Known Issues

When (for example) three lines are added to a phone, and one of them is removed, so the phone now has two lines, the deleted line will not be disabled on the phone.
To resolve this, set all other lines (up to the actual maximum line count of the phone) with Custom Configuration (in the Cloud PBX). This will blank the relevant fields in the phone.

SIP-T26P requires HTTP provisioning, see below for detail.

Process

  • Configure Button Layouts (see here)
    • Ensure that you create Button Layouts for Line Keys, as well as Expansion Modules, if they’ll be used.
      • If you have multiple Expansion Modules, numbering starts closest to the phone, and works outwards.
      • On cordless base stations, a Button Layout is used to map the Accounts (Lines) to handsets.
  • Configure Phones (see here)
    • Do not provision virtual extensions to phones, only extensions that are “part of” a virtual extension.
  • Provision phones using one of the below methods
    • DHCP Option Method (see here)
    • Provision on Yealink Phone Method (see here)
      • This same concept applies to any other model of phone
    • Some Phones won’t provision due to TLS issues
      • Only upgrade firmware manually to resolve TLS provisioning issues.
        • Using this method to solve other issues will result in firmware being overwritten by the Cloud PBX, leaving the phone in an inconsistent state.
      • Notes
        • This is particularly known to occur on the following models of phone / base.
          This is specific to earlier firmware versions, and may occur on models other that those listed. Only try to resolve this on SIP-T4xx phones, not SIP-T2xx.

          • Yealink SIP-T2xx
            • Firmware update will not fix this. Requires HTTP provisioning, rather than HTTPS.
          • Yealink SIP-T41P
          • Yealink W52P
          • Yealink W56P
        • The handset firmware is irrelevant in this situation, as auto provisioning will upgrade this once the phone / base is working correctly.
      • Upgrade the firmware of the phone / base to it’s latest firmware
      • Factory reset the phone / base
      • The phone will now look for the DHCP Option, and attempt to provision
      • If you’re not using the DHCP Option, please provision on the phone itself (see here).
        • The same theory applies to any other model of phone
  • If you still have an issue, please contact Vetta Online.
