Use Your OBi202 with OBiBT as a Cellular (GSM or CDMA/PCS) Mobile Phone Service Gateway for a SIP IP Phone

Important Note:  Before you begin to make configuration modification to your OBi device, please note that modifications are best made via the OBiTALK portal OBi Expert configuration pages. Using OBiTALK, the set-up of Google Voice and SIP accounts is easy.  In the OBiTALK portal Device Configuration page for your unit, you will find the access button for the OBi Expert configuration pages.  Click Here for more information on OBi Expert configuration.

What Does this Accomplish?

-          Make calls from a SIP IP phone to the cellular / mobile network via the
paired mobile phone’s service plan.
-          Receive calls on the SIP IP phone from the cellular / mobile network via the
mobile phone’s service plan.
-          The Caller ID will be the original caller’s incoming phone number.
-          You do not need a static IP address on the IP phone. It will get its IP address from the OBi202.




What You Need

As shown in the above diagram, you will need the following:
-          An OBi202 with an available “SP” service to be configured as a SIP Proxy for the IP phone.
-          An OBiBT Bluetooth USB dongle.
-          A mobile phone with active service paired and connected with the OBiBT dongle.
-          A SIP IP phone (Cisco SPA508G shown here) installed on the LAN-port side of the OBi202.
-          An available EXT (or Line) on the IP phone to be used with the OBi202.

How to Set-up the OBi202 & IP Phone

Without loss of generality, we assume:
-          You will use ITSP Profile B and SP2 on the OBi202 to configure it as a proxy for the IP phone.
-          Use EXT 1 on the IP phone for this configuration, with the private number 1001
-          In this example, the OBi202’s OBi Number is: 500 111 345

On the OBi202, set-up the following parameters:
-          ITSP Profile B/General/SignalingProtocol = SIP (default)
-          ITSP Profile B/SIP/Proxy = 127.0.0.1                (a dummy non-empty value)
-          ITSP Profile B/SIP/X_SpoofCallerID = yes (or checked)
-     SP2/X_ServProvProfile = B
-          SP2/X_UserAgentPort = 5061 (default) 
-          SP2/X_RegisterEnable = no (or unchecked) 
-          SP2/AuthUserName = 1001 
-          SP2/AuthPassword = AnyPhonePassword 
-          SP2/X_Proxy = yes (or checked) 
-          SP2/X_InboundCallRoute = {1001>:BT} 
or just add the rule to the beginning of the current X_InboundCallRoute value. 
-          OBiBlueTooth/InboundCallRoute = {SP2(1001@local_client)}

On the Cisco SPA50xG IP phone, set-up the following parameters (or equivalent on other phones):
-          EXT 1/Proxy = 500111345.pnn.obihai.com:5061
-          EXT 1/User ID = 1001
-          Ext 1/Password = AnyPhonePassword
-          EXT 1/Register Expires = 60
-          EXT 1/Register = yes
-          SIP/Send Resp To Src Port = yes
