Hi kamailio dev:
I am writing a module to implement some features, my version is 4.1.2, I am not 
sure if it is a known issue, I found:
1. When I get a INVITE request with from/to like from:"display"<a...@sip.com>, 
then I call tm's new_dlg_uas with the sip req, now the dlg's rem_uri set as 
value: "display"<a...@sip.com>;
2. After that, when I need use the dlg to send BYE with tm's req_within with 
the above saved dlg, the print_to function will check the rem_uri's first value 
if "<" or not, now my uri has display name, so the outgoing BYE's to header 
becomes to:<"display"<a...@sip.com>>, is it wrong? Should we check the last 
char in the rem_uri as ">"?

The detail code is :
static inline char* print_to(char* w, dlg_t* dialog, struct cell* t)
{
    t->to.s = w;
    t->to.len = TO_LEN + dialog->rem_uri.len + CRLF_LEN
        + ((dialog->rem_uri.s[0]!='<')?2:0);

    memapp(w, TO, TO_LEN);
    if(dialog->rem_uri.s[0]!='<') memapp(w, "<", 1);
    memapp(w, dialog->rem_uri.s, dialog->rem_uri.len);
    if(dialog->rem_uri.s[0]!='<') memapp(w, ">", 1);
....
