[SR-Users] lookup(aliases) issues with 5.2

[Daniel-Constantin Mierla]

Hello,

reading again I see that the error with the host uri is printed from the
C code. I thought of another issue that was reported related to IPv6
addresses in the URI that kamctl rejected.

The problem is that the underscore is not allowed in hostname: the
relevant standard is RFC 1123, section 2.1 "Host Names and Numbers"
which limits host names to letters-digits-hyphen.

I checked the commits log and it seems this more strict verification was
added by next commit:

commit 4994960324d5353222b3de08515bed07802ab7bc
Author: Juha Heinanen <jh at tutpro.com>

    core/parser: more strict parsing of sip uri host

Regarding the $ALL_METHODS not being defined, iirc, you should set it to
. (or maybe -1 in this case).

Cheers,
Daniel
