BYOD Provisioning Updates | AT&T Office@Hand

We are upgrading the AT&T Office@Hand environment, which will require manual provisioning of Bring-Your-Own-Device (BYOD) desk phones and adapters.

If you have a third-party phone manually provisioned with AT&T, you will need to redo the manual provisioning.

Manually provisioned phones include:

  • Cisco, Polycom, or Yealink phones that do not have a valid factory-installed device certificate even if it is included on the list of devices that can be configured via Assisted Provisioning.
  • Other SIP-Compliant phone brands such as Snom, Aastra, Grandstream, Panasonic, etc.

You can check your third-party phones on your AT&T Office@Hand account.

  1. Log into your AT&T Office@Hand account, and go to Phone System > Phones and Devices.

    Log into your AT&T Office@Hand account, and go to Phone System > Phones and Devices.

  2. Click the Device drop-down and choose Existing Phone.

    Click the Device drop-down and choose Existing Phone.

  3. Get the Session Initiation Protocol (SIP) Settings. Select the Outbound Proxy based on the location of your device to reduce latency issues.

    SIP or Session Initiation Protocol is a communications protocol for signaling and controlling multimedia communication sessions, including voice over IP. This information is needed when manually provisioning your IP Phone with the AT&T Office@Hand service. The SIP information varies per digital line. To find the SIP information on the AT&T Office@Hand online account, go to How do I get the SIP settings on the AT&T Office@Hand Online Account?

  4. Access Phone’s user web interface to enter SIP Settings. Refer to your phone’s user guide or contact your phone’s support hotline for specific instructions.

    Note: Some AT&T Office@hand desk phone features will not work on manually provisioned phones. It may vary depending on your desk phone model.

  1. Log in to your AT&T Office@Hand account as an Administrator.
  2. Click Phone System, then Phones & Devices.
