"*allcredentials" is a valid SIP URI user-part. See RFC 3261 section
25.1. The relevant grammar rules are:
SIP-URI = "sip:" [ userinfo ] hostport uri-parameters [ headers ]
userinfo = ( user / telephone-subscriber ) [ ":" password ] "@"
user = 1*( unreserved / escaped / user-unreserved )
unreserved = alphanum / mark
mark = "-" / "_" / "." / "!" / "~" / "*" / "'" / "(" / ")"
(Note that "#", though it is also a DTMF symbol, is *not* a valid
character in a user part, and has to be represented by "%23".)
