Setting up a Third Party SIP Phone
Article #2652

How do I set up a SIP Phone not purchased from Office@Hand for AT&T?

Provisioning is when you connect a phone with the Office@Hand cloud platform for secure voice, audio conferencing, and online meetings.

You can get a pre-configured and fully provisioned phone that is ready to use when plugged in to a high speed internet connection from Office@Hand. You may also use the device that you already have, maybe from a previous or different provider, bought directly from the manufacturer/ distributor, or a phone that was passed on with Office@Hand. As long as the device is one of which Office@Hand recommends or that it is SIP Compatible.

Provisioning a third party SIP Phone

You can provision your device in 2 different ways:

Assisted Provisioning

Assisted Provisioning is available on some phone models. In Assisted Provisioning, the phone’s Serial Number is entered on your Office@Hand Online account, and Office@Hand’s Provisioning Server address is entered inside the phone’s Menu. This allows the phone to automatically connect, download, and update the information. Since your system is in the cloud, updates and new features appear automatically.

IMPORTANT: Check if your device is included on the list of phones that can be configured via Assisted Provisioning. If your phone is on the list, you will see a link where you can view the instructions for assisted provisioning. If your phone is not on the list, then continue below for Manual Provisioning.

Manual Provisioning

Manual Provisioning is performed when a device is not on the list of supported devices for Assisted Provisioning.

In Manual Provisioning, SIP Settings are entered manually in the phone’s menu or web interface. The Authorization information and SIP settings for the phone are entered manually in the phone’s Menu or Web Interface, to be able to ONLY register with the Office@Hand servers. Manual Provisioning will not maintain communication for updates to the phone, only the registration with the service.

  • Manual Provisioning will not allow the phone updates from Office@Hand’s servers.
  • Manual Provisioning will not pull the firmware required for Office@Hand’s features.
  • Users with manually provisioned phones will not be able to use Presence.
  • Phones manually provisioned will not have softkeys for Paging and Intercom.

To manually provision your phone, you must first, add a phone number that will be assigned to your existing device. Scroll down for instructions.

Note:  If your device also has a phone number assigned to it, proceed to How do I get the SIP Settings needed for Manual Provisioning.
