Ok, got it all to work. Used the document Configuring an OBi Voice Service Bridge to connect a legacy IP Phone. Using the following:
And so, ITSP Profile D and SP4 on the OBi202 shall be configured as a proxy for the IP phone.
• ITSP Profile D/General/SignalingProtocol = SIP (default)
• ITSP Profile D/SIP/ProxyServer = 192.168.1.10 (ie IP address of our SPA962 IP Phone)
• ITSP Profile D/SIP/ProxyServerPort = 5063 (SIP listening port for our IP Phone)
• ITSP Profile D/SIP/X_SpoofCallerID = yes (or checked, this will ensure we pass the caller ID through)
Next, create the local voice service that the IP phone will use as its proxy:
• SP4/X_ServProvProfile = D (We're saying use the ITSP D profile with this voice service)
• SP4/X_UserAgentPort = 5063 (Note:'you'can'choose'a'port'that'you'prefer,'just'be'sure'to'use'the'
same'port'number'throughout'the'tutorial
• SP4/X_RingProfile = B
• SP4/X_RegisterEnable = no (or unchecked)
• SP4/AuthUserName = 1001 (This can be defined by you, but needs to be the same on the IP Phone)
• SP4/AuthPassword = AnyPhonePassword (Once again, you can define this, but must be the same on
the IP Phone)
• SP4/X_Proxy = yes (or checked)
Configure the IP phone to register to the OBi and use it as it's proxy
On the IP phone, set=up the following parameters:
• EXT 1/Proxy = 192.168.1.20:5063 (ie: IP address of OBi202)
• 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
Then to make both phones ring on incoming calls from either SP1 GV or SP2 Callcentric I added SP1/X_InboundCallRoute = {ph,ph2,sp4(1001)}
I am sure I can fine tune this setup, but for now I can call out using GV, Callcentric or Cellphone via Bluetooth from the IP or standard phone.
Thanks for all your help!
