I've been working on Kamailio websocket
integration and I believe I'm
having issues with the IPv6 address representation in the Contact
header's alias parameter. After Googling, it appears after
https://github.com/kamailio/kamailio/commit/814c08f3 the IPv6 contact is
represented in brackets []. However, it when using websockets, and the
alias= parameter uses brackets [] around and IPv6 address, there are
message parsing issues.
With a header such as the following
Contact:
<sip:wstest1@example.com;gr=urn:uuid:26140e27-0ab7-4e65-98e3-3d0909b1434
e;
al ias=[2001:db8:0:1]~48768~6>
Asterisk 13.2.0 will give the following error:
pjsip:0 <?>: sip_transport. Error processing 1855 bytes packet from
UDP
10.77.79.3:5060 : PJSIP syntax error exception when parsing 'Request
Line'
header on line 12 col 129:
And when sipjs, or jssip are used with either Firefox or Chrome, they
send
garbage in the ACK request URI:
Kamailio logs something like the following and the ACK cannot be
processed:
WARNING: sanity [sanity.c:236]: check_ruri_scheme(): failed to parse
request uri [�a�{1me▒s�na@50�9���1.�8:�2v0;i��a��=11>7�n7x>10O�2v0~1]
Is it proper to have [] brackets around the IPv6 alias address in the
Contact header? Does the value need to be quoted?
If I force the browser to use IPv4, without changing anything else, both
jssip and sipjs work perfectly in Firefox and Chrome.
It seems that the topoh module doesn't cope with this well. Disabling
the
topoh module seems to resolve the issue, unfortunately.
I've added some additional information and an example INVITE here:
https://github.com/kamailio/kamailio/issues/120
Wrote in the issue page as well:
Parameter values for SIP URI must not be enclosed in quotes (as per sip
rfc).
However, given that the IP open appear as value of a uri parameter, I
would expect '[' and ']' to allowed as chars in uri parameters. The SIP
grammar has to be checked.

I don't doubt that you're right, Daniel. I have asked for some assistance on
the PJSIP mailing list, as I get the same error from both Asterisk 13 and
CSipSimple nightly build. Since Asterisk has moved to PJSIP, this could pose
a significant interoperability issue.
