The Local-Network profile in the framework requires "_sipuaconfig" concatenated with the local network domain to be used as the host part of the Request URI. 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.
