SP1 is connected to a Google Voice account, number 123-456-7890
SP2 is registered to an Asterisk SIP account, number 4567
With these SP1 settings inplace:
CallForwardUnconditionalEnable (x)
CallForwardUnconditionalNumber SP2(9876)
All inbound calls to the Google Voice number 123-456-7890 make the Asterisk SIP 9876 number phone ring.
It works everytime anyone calls 123-456-7890.
The only problem is the caller ID of the person calling 123-456-7890 does not show on the 9876 phone.
Regardless of the caller you always see the caller ID 4567, because that is the Asterisk extension from where the call (seems) to originate.
I can understand that, but ...
Is there any way to make the actual caller's ID come thru (or pass thru) the OBi110 to Asterisk to the SIP extension?
FYI, when I set Google Voice to send calls to my mobile phone, I get the actual caller's ID.
