CallerID with Forwarding from PSTN to GV

[jerome]

Hello, my config is the following:

OBI100 + PSTN + GV

Incoming call thru the PSTN then forward to GV with a number as SP1(xxxxxxxxx)
the functionality is good however I got the callerid of the GV not from the incoming PSTN call...

how do I do this ?

Thanks in advance.

You don't.  One cannot change the CID info of an outbound google voice call.  If you want that capability you'll need to use a real voip provider that lets you control CID info.  Callwithus is one that comes to mind. Others may allow this too.

You can pass CallerID via SIP routing to a cell phone or a computer. Install a softphone on the device, register it to a free SIP provider and route the call via SIP URi. You need an SIP trunk defined on the OBi110 or define a dummy SIP trunk.
