Hi,

I'm trying to create a ruri from contact header like following :

In request route I've saved contact header in a hashtable using htable module.
request_route{

---------------------
---------------------
#!ifdef WITH_HASH
         if (is_method("INVITE") && !has_totag()){
                 xdbg ("Contact [$ct] with Callid [$ci]");
                 $sht(a=>$ci) = $ct;
         }
 #!endif

----------------
}

And in route[WITHINDLG]

route[WITHINDLG] {

---------------------------
---------------------------
 #!ifdef WITH_HASH
                                 xdbg ("ruri [$ru]");
                                 if ($sht(a=>$ci) != $ru){
                                         $ru = ($sht(a=>$ci));
                                         xdbg ("rewriting ruri to [$ru]");
                                 }
 #!endif

But it log shows that its unable to parse the uri :

[4039]: DEBUG: <core> [parser/parse_uri.c:1277]: parse_uri: bad uri,
state 0 parsed: <<sip> (4) / <<sip:2020@103.23.169.2:64358>> (29)

I'm not understanding what's wrong with that. May be the port part
should be discarded, but how i'm gonna do that?

It looks like $sht(a=>$ci) is empty. I see that you have "xdbg ("Contact [$ct] with Callid [$ci]"); " line, but you didn't show us that line at the debug.
If you add $ci to the debug information at the route[WITHINDLG] and show full debug from INVITE to BYE it will help to find where the mistake is.

And i think it would be better if you change if ($sht(a=>$ci) != $ru) to if ( $sht(a=>$ci) != $null && $sht(a=>$ci) != $ru) , because when $sht() is empty it always not equal to $ru.
