[OpenSER-Users] uri transformation errors in 1.2

[Andreas Granig]

Hi Daniel,

Very strange, since I currently tried a fresh version of latest 1.2 
without any modifications, and it still doesn't work for me. After some 
tries, I get this errors:

unprocessed uri='sip:test at 192.168.101.11;sw_domain=sipwise.com'
domain=''
ERROR: parse_uri: bad host in uri (error at char
ERROR: parse_sip_msg_uri: bad uri <sip:agranig@>
xl_get_ruri: ERROR while parsing the R-URI
processed uri='<null>'
ERROR: parse_uri: bad host in uri (error at char
ERROR: parse_sip_msg_uri: bad uri <sip:agranig@>

You can reproduce this easily using sipsak (just adapt the ruri-ip):

# sipsak -l 7060 -f /tmp/inv.txt \
	-s sip:test at 192.168.101.11;sw_domain=sipwise.com

The file /tmp/inv.txt contains:

INVITE sip:test at 192.168.101.11;sw_domain=sipwise.com SIP/2.0
