The OBiTALK Service
OBiTALK is a proprietary protocol for communications among phones or Poly ATA devices and
OBiTALK device management servers.
The protocol is intended for two main purposes:
● Peer-to-peer calling between OBiTALK devices
● Device management by OBiTALK servers
Every OBiTALK phone or Poly ATA device comes with one instance of the OBiTALK service with the
(fixed) factory-assigned 9-digit device OBi number as the user ID of the service. devices can call each
other by dialing the other party’s OBi number.
The OBiTALK service also enables you to view and change the settings of your phones from the
PDMS-SP portal. If you disable the OBiTALK service in your phone’s configuration, you can’t place
OBiTALK voice calls or manage device features through the PDMS-SP portal.
Enable the OBiTALK Service
The OBiTALK service is enabled by default, unless disabled through Zero Touch Provisioning.
For information on Zero Touch customization, see the
