OBiTALK Service
OBiTALK is a proprietary protocol developed by Obihai Technology for communications among OBi devices and to
OBiTALK device management servers. The protocol is intended for two main purposes: a) Peer-to-peer calling between
OBi devices, and b) Device management by OBiTALK servers. Every OBi device comes with one instance of the OBiTALK
service with the (fixed) factory-assigned 9-digit device OBi Number as the userid of the service. OBi devices can call
each other by dialing the other party’s OBi Number.
The OBiTALK service is enabled with the parameter
OBiTALK Service
::
Enable
and is enabled by default (unless it is
disabled through ZT Customization).
Through OBiTALK, the user can start calling another OBi device out-of-the-box without any configuration. However, the
phone must be able to reach out to the Internet to make an OBiTALK call. To call another number, from the phone dial
**9 followed by the 9-digit OBi number. For your convenience, Obihai maintains an
Echo Server
at the reserved OBi
Number
222 222 222
. Users can call this number to do a quick
Echo Test
after listening to a short announcement at the
beginning. If the test is successful, the user will hear their voice echoed back as they talk during the test. This serves as
a rudimentary check that the network and equipment is set up and functioning correctly.
An administrator such as an ITSP may desire to limit OBiTALK calls just to the Obihai Echo Server. To do this the
administrator can change the value of
OBiTALK Service
::
DigitMap
to:
(<ob>222222222|ob222222222)
.
Obviously, you can change or add more OBi numbers to this digit map by following the same pattern. A simple way to
disable OBiTALK voice calls completely is by setting

; you will
not be able to do Echo Test in that case.
The OBiTALK service also makes it possible to view and change the settings of your OBi devices from the OBiTALK
portal. If the OBiTALK service is disabled in the device configuration, both OBiTALK voice calls and device management
features will not be available.
