Service Account Credentials

Credentials are required for all SP services only; they are neither required or available for OBiTALK and OBiBluetooth
services. At the minimum, a username for the SP service account must be configured with the parameter:
SPn Service- Service Credentials::
If a password is also required for authentication to the server, put it into:
SPn Service- Service Credentials::
In a less common situation where the username used for SIP authentication is different from the account username,
this can be achieved by setting the account username in
username for authentication only in
is not specified, it is used for both as the account username and for SIP authentication. Note also that if
URI
is not specified, the phone considers the service as disabled also.

Servers

The equipment operated at the service provider side can be generically referred to as the Servers. For SIP/SP services,
we can call them SIP Servers. For the Google Voice service, we can call them Google Voice Servers. And for the OBiTALK
service, we can call them OBiTALK Servers. There are no external servers required for the OBiBluetooth service; one can
think of the server as built into the phone software in this case.
Another commonly used term for the server equipment is Soft-Switch. A soft-switch typically offers a lot of extra
business productive/collaboration features in addition to basic phone services. In fact, there are a few popular open-
source and commercial soft-switch implementations such as BroadSoft, MetaSwitch, and FreePBX, that the OBi1000
phones fully support.
No matter what technology is used in the service provider side equipment, it must be provisioned into the phone
configuration as a domain name or an IP address; a port number is also required if the server is not listening at the
standard port (5060). Note that since Google Voice and OBiTALK servers are already known by the phone, there is no
need to configure the server domains for these services. For other SIP/SP services, the proxy server must be configured
in the parameter: ITSP Profile X –
in ITSP Profile X – SIP:: ProxyServerPort
needed when the device-facing server is a Session Border Controller (SBC). Similarly if the outbound proxy is not
listening at the standard port, configure the correct port value in
and

the same as the SIP Proxy Server if they are not specified separately.
SIP Transport refers to the transport protocol to use to exchange SIP messages with the server: UDP, TCP, and TLS are
supported by the phone. The transport protocol is configured by the
parameter. For TCP/TLS, the phone must start a TCP/TLS connection with the
messages must be exchanged using the SAME connection. If

Trunk Capacity

This refers to the maximum number of simultaneous calls that is allowed on the trunk. For OBiBluetooth service, this
value is always and is not configurable. For other services, this value can be set in the parameter
1
each service. The default value is 2 for all services. For OBiTALK service, the maximum value is 4. For Google Voice
services, the maximum value is 2. For other SIP/SP services, the value must be set to no larger than the maximum
number of simultaneous calls allowed by the service provider.

Basic Incoming Call Handling

For each incoming call arriving at the phone from a specific trunk, the phone handles it in the following order:
AuthUserName
AuthPassword
SPn Service- Service
. In other words,
AuthUserName
SIP:: . If the listening port is non-standard, configure the correct value
ProxyServer
. The OutboundProxy
parameters are rarely needed; the phone assumes the SIP Registrar is
instead. With the
