Sp N A S Proxy For Asip Ip Phone - Obihai OBi110 Administration Manual

Using SPn as a Proxy for a SIP IP Phone
(Available on OBi202 and OBi302 only)
An SP service may be set up as a proxy for a legacy IP phone, to let the phone access OBiTALK, OBiBlueTooth, OBiPLUS (on
SPn), or Google Voice service (on SPn) installed on the OBi. This proxy mode of operation must be explicitly enabled in the
SP 's configuration on the OBi; it is disabled by default. The IP phone using this proxy service is known as the local_client of
the SP service. It must be installed on the LAN side of the OBi device.
In this mode, SPn will accept SIP Registration from the client device from the LAN side, which must be using the same user-
id and password as this SPn's AuthUserName and AuthPassword parameters, for authentication. This client device may also
send SIP INVITE to the OBi at this SP to make calls; this SP's InboundCallRoute must be setup with the proper routing rule to
handle calls from the local_client.
The SIP Proxy Server parameter on the client device must be sent to:
<obi-number>.pnn.obihai.com:<spn-user-agent-port>
where <obi-number> is the 9-digit OBi number of this device, and <spn-user-agent-port> SPn's X_UserAgentPort parameter.
For example, SP1 has a local_client with the user-id 4086578118. The client wishes to make and receive calls on SP3 which
has been set up with Google Voice. The SP1 InboundCallRoute shall include the following rule:
{4086578118>:sp3}
The SP3 InboundCallRoute shall be: {sp1(408657118@local_client)}
