I'm pretty sure there was a DNS record type for telephone numbers, but it was never picked up for use by anyone. If it exists, it would be in this document:
http://www.iana.org/assignments/dns-parameters/dns-parameter...
I quickly found record types for ISDN and X.25, but I don't have time to pick through for PTSN.
