This is a follow up question to https://ask.wireshark.org/question/19... Once the call has been established and the caller and the called ip addresses are known why does the provider need to stay involved in the call given the potential for abuse by cold callers?
I'm not seeing the correlation between '"providers need[ing] to stay involved" and "the potential for abuse by cold callers". But one reason the provider needs to stay involved in the call is because the provider provides call control facilities (with optional media) which require the media to flow through their equipment, not least of which Lawful Intercept (LI). But also media conversion, e.g., PSTN / VoIP / mobile, RTP rate conversion (packet rate), codec conversion.
Thank you again, in Australia we have a 'do not call' register which the cold callers simply ignore and more than likely they are calling from beyond our legal jurisdiction. Pity we can't track their IP and black list them.
