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.
