[OpenSER-Users] uri transformation errors in 1.2

[Andreas Granig]

Hi Bogdan,

No, the r-uri is definitely ok. Here's the real-world snipped and 
logging example. The snipped is placed as very first code in route[0]:

	if(uri =~ ";sw_domain=.+")
	{
		xlog("L_INFO", "unprocessed uri='$ru'\n");
		$var(swdom) = $(ru{uri.param,sw_domain});
		xlog("L_INFO", "domain='$var(swdom)'\n");
		$ru = "sip:" + $rU + "@" + $var(swdom);
		xlog("L_INFO", "processed uri='$ru'\n");
	}

This works well for ~5 times, then I get:

unprocessed uri='sip:agranig 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>'
msg_uri: bad uri <sip:user@>
