PaulS – Here is the direct SIP calling version that is independent of OBiTALK. This assumes that both OBi devices are in the same LAN subnet.
In both OBi110s I have used sp2, mostly because I have used this in previous posts and I'm doing a lazy cut and paste for some of this post
Remote OBi address:port 192.168.1.14:5473
PBX OBi address:port 192.168.1.10:5471
Remote OBi 200654321:
Service Providers -> ITSP Profile B -> SIP -> ProxyServer : 127.0.0.1
Service Providers -> ITSP Profile B -> SIP -> X_SpoofCallerID : checked
Voice Services -> SP2 Service -> Enable : (checked)
Voice Services -> SP2 Service -> AuthUserName : 1234
Voice Services -> SP2 Service -> X_RegisterEnable : (unchecked)
Voice Services -> SP2 Service -> X_ServProvProfile : B
Voice Services -> SP2 Service -> X_UserAgentPort : 5473
Voice Services -> SP2 Service -> CallerIDName : Whatever
Voice Services -> SP2 Service -> MaxSessions : 4

{(@@.):sp2}
PBX OBi 200123456:
Service Providers -> ITSP Profile B -> SIP -> ProxyServer : 127.0.0.1
Service Providers -> ITSP Profile B -> SIP -> X_SpoofCallerID : checked
Voice Services -> SP2 Service -> Enable : (checked)
Voice Services -> SP2 Service -> AuthUserName : 5678
Voice Services -> SP2 Service -> X_RegisterEnable : (unchecked)
Voice Services -> SP2 Service -> X_ServProvProfile : B
Voice Services -> SP2 Service -> X_UserAgentPort : 5471
Voice Services -> SP2 Service -> CallerIDName : Anything
Voice Services -> SP2 Service -> MaxSessions : 4
Voice Services -> SP2 Service -> X_InboundCallRoute:
{(1234):li}
Physical Interfaces -> LINE Port -> InboundCallRoute
{sp2(obi@192.168.1.14:5473)}
If you would like the PBX OBi's phone to ring as well as the Remote OBi's phone use:
{ph,sp2(obi@192.168.1.14:5473)}
Using these settings CallerID should be passed both ways. CallerID of the remote OBi is its AuthUserName.
