Very good catch.

RFC 3261 section 19.1.2 disallows escaping hostname.

attempt to
improve robustness by treating received escaped characters in the host
component as literally equivalent to their unescaped counterpart. The
behavior required to meet the requirements of IDN may be significantly
different."

Subject: Re: SIP Configuration Framework uses
underscore in SIP URI
Geir is correct that _ can't appear bare in the hostname part
of a SIP URI.
It can appear %-escaped.
Is that what the profile should be using?

Our SIP stack does not view this as valid SIP URI, and rejects the
message. AFAICC RFC 3261 seems to agree with our parser.
IMHO, using underscores in DNS host for finding services
related names
in DNS queries is one thing. Changing the grammar of a SIP URI
potentially breaking parsers is quite another matter.
