<p>Hello,</p>
<p>usually you should not loop requests locally, unless a very
special case -- do you do the loop routing because of a need or
just happens but you don't know why?</p>

<div>Hello all,<br>
<br>
I have been toying with kamailio lately, and I thought I had
gotten to the point where I had a mostly working (tm)
prototype. I gave it a test drive with some real calls,
however, and an issue manifested at least once, where homer
received packets originating from the kamailio host, and whose
destination was also the kamailio host.<br>
<br>
The dialog this manifested in is a generally problematic one,
with many retransmissions occurring because of slow database
access (I haven't implemented htable caching yet). No packet
capture over the network is actually taking place, I'm copying
everything to homer with "trace_mode"set to 1.<br>
<br>
Homer shows these messages like in the screenshot: <a

Can something like this be triggered by misconfiguration in the
routing scripts? Should it worry me and should I dig into it
more? Could it be a bug of the siptrace module and nothing bad
actually took place? I'm not sure where to start with this, so
any input would be greatly appreciated. Thanks!<br>
