You can use a softphone on a computer to send/receive calls to/from your OBi.
This setup assumes GV is defined on SP1 and a SIP provider is defined on SP2.
If SP2 is undefined, create a dummy definition like this:
Service Providers -> ITSP Profile B -> SIP -> ProxyServer: 127.0.0.1
Voice Services -> SP2 Service -> AuthUserName: anything
Voice Services -> SP2 Service -> X_RegisterEnable: unchecked
Voice Services -> SP2 Service -> X_ServProvProfile: B
OBi110
Service Providers -> ITSP Profile B SIP -> X_SpoofCallerID: Checked
Voice Services -> SP2 Service -> X_InboundCallRoute:
{OBi110>(Msp1):sp1,{ph}
Physical Interfaces -> Line Port -> InboundCallRoute:
ph,sp2(anything@192.168.1.100:5060)
Change 192.168.1.100 to the IP address of the computer running Phonerlite.
5060 is the Port number for Phonerlite
Download and install Phonerlite:
http://www.phoner.de/PhonerLiteSetup.exeWhen you start Phonerlite I think a wizard will popup because no accounts are defined.
Proxy: 192.168.1.110:5061 (The IP address and Port of SP2 on the OBi110)
Click right arrow.
User Name: OBi110
Click right arrow.
Change Profile Name: OBi110
Click check mark
Uncheck box next to Register
Save
To change the default port (5060) click Network tab
Change Local Port and click Save
Dial a number and click the green phone symbol.
Click red phone symbol to hang up.
Edit:
If you want to initiate a call from a computer and have GV do a callback to the OBI, the above configuration doesn't apply.
The above will make and receive calls from a computer.
