99%? 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.
I do believe that if the robo call/scam/fraudulent call issue does not
get resolved people may eventually start to give up and just use apps
like that. Many probably have already.
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 From: address.
