The outgoing caller ID works well when using Google Voice.
But for SIP service, I tested both voipbuster and voipstunt, even though I do set up the caller id phone number through those website and caller ID works when using their client software or PAP2, but for OBI110, it doesn't work. I set up the CallerIdName field in the SPx service menu and enable X_SpoofCallerID but no help.
Is there anybody have the solution?
Thanks a lot.
