Well, I already understand what's happening, parse_uri.c contains:

     case TEL_URI_T:
     case TELS_URI_T:
        /* fix tel uris, move the number in uri and empty the host */
        uri->user=uri->host;
        uri->host.s="";
        uri->host.len=0;
        break;

This is, a TEL uri is stored in a struct sip_uri with empty host.
When modyfing $rU the uri will be parsed again to resolve destination and so, 
and it will fail since "@" is automatically added (shouldn't exist in a TEL 
uri).

I've realized that parse_uri() is called after doing "$rU=", but I'm 
inspecting pv_set_ruri_user() and don't find it. Could I know where 
parse_uri() is called after "$rU=" operation?

Thanks.
