I configured my VoIP account with ICS Internet Calls, so I can call over WiFi using a VoIP account. However call receivers don't get my Caller ID, instead it comes up as withheld/unknown number.
There are some additional fields in Internet Calling that I haven't populated.
Is it part of the SIP protocol to pass the Caller ID and can it be configured?
P.S.: When I use VoIP program from my VoIP provider, I can configure Caller ID.
