I use Phonerlite on my Windows PC. Use OBi Expert to make the following config changes.
Create a dummy SIP definition on SP2 like this:
Service Providers -> ITSP Profile B -> SIP -> ProxyServer: 127.0.0.1
Service Providers -> ITSP Profile B SIP -> X_SpoofCallerID: Checked
Voice Services -> SP2 Service -> AuthUserName: anything
Voice Services -> SP2 Service -> X_RegisterEnable: unchecked
Voice Services -> SP2 Service -> X_ServProvProfile: B
Voice Services -> SP2 Service -> X_InboundCallRoute:
{OBi200>(Msp1):sp1},{ph}
Voice Services -> SP1 Service -> X_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:

Proxy: 192.168.1.110:5061 (IP addr & Port of SP2 on the OBi200)
