If a phone number was used than the PSTN was used. The
fact that SIP is involved in part or all of the call path
is not very relevant except for peer-to-peer stuff like
whatsapp, skype, signal, telegram, etc. (and even those
don't use SIP, but I think you meant voip more than SIP
specifically) Even some of those can use e.164 for part or
all of the path.</span><br

do believe that if the robo call/scam/fraudulent call

<p>We're probably not communicating because lots of carriers are
using VoLTE which SIP end to end, so that is a lot more that 1%. I
know that my local telco uses SIP over fiber at the little
pedestal which terminates POTS and never touches SS7 anything from
what I can tell. e.164 addresses are a relic of legacy telephony
signalling, even if they're still used to make the user part of a
