Quotejust remove the old device
If you deleted the OBi100 from OBiTalk then add it back, otherwise just delete SP1.
Use OBi Expert to make the following config changes:
OBi100
Service Providers -> ITSP Profile A General -> SignalingProtocol: SIP
Service Providers -> ITSP Profile A SIP -> ProxyServer: xx.xx.xx.xx
Service Providers -> ITSP Profile A SIP -> ProxyServerPort: ppp1
Voice Services -> SP1 Service -> AuthUserName: OBi100
Voice Services -> SP1 Service -> X_RegisterEnable: (unchecked)
OBi200
Voice Services -> SP1 Service -> MaxSessions: 4
Voice Services -> SP1 Service -> X_InboundCallRoute:
ph,sp4(0@yy.yy.yy.yy:ppp2)
Service Providers -> ITSP Profile D SIP -> ProxyServer: 127.0.0.1
Service Providers -> ITSP Profile D SIP -> X_SpoofCallerID: Checked
Voice Services -> SP4 Service -> X_ServProvProfile: D
Voice Services -> SP4 Service -> AuthUserName: OBi200
Voice Services -> SP4 Service -> X_RegisterEnable: (unchecked)
Voice Services -> SP4 Service -> X_InboundCallRoute:
{>0:ph},{OBi100>(Msp1):sp1}
Replace xx.xx.xx.xx with the IP address of the OBi200
Replace yy.yy.yy.yy with the IP address of the OBi100
If you don't know the IP addresses, dial ***1 from attached phone
Set ppp1 to the value of OBi200's SP4 Service X_UserAgentPort
Set ppp2 to the value of OBi100's SP1 Service X_UserAgentPort
From the OBi100:
Dial 0 to ring the OBi200
Any other number will be routed to SP1 on the OBi200
Inbound calls from GV will ring both devices.
You can make simultaneous calls from the devices
Edit:
I made some changes to the above.
