[v164]

You would need to deal with the other directories (e164.arpa, e164.info, etc). SipBroker doesn't handle ENUM registrations, it just provides a convenient way to do ENUM lookups and route SIP calls via ENUM.

You don't need to have your PSTN number registered in all directories - one is sufficient. SipBroker automatically checks all five of these (in parallel), and routes the call to the SIP URI in whichever ENUM registry contains an entry.
