<p>Correct, Max-Forwards stays the same on each ReINVITE and the
CSeq increments by 1 each time. All other headers stay the same.
I have no idea what is broken with the client to continually
ReINVITE in a loop. We accept the ReINVITE with an OK and we
receive an ACK back and then immediately another INVITE and so it
goes on until the call is terminated.</p>
<p>I'm less interested in working out what is broken on the client
end and more interested in protecting our network.</p>
<p>Thanks,</p>

all,<br>
<br>
I have a misbehaving SIP client which is repeatedly sending
SIP ReINVITE <br>
messages over and over again (in the hundreds) and want to
enforce a <br>
limit on the number of ReINVITE messages per Call to stop this
in it's <br>
tracks. The CSeq is incrementing on each ReINVITE.<br>
<br>
Are there any config settings to limit the number of ReINVITEs
on a <br>
single Call/Dialog? I was going to possibly keep a count of
the INVITEs <br>
using a cache variable based on the Unique CallID but wanted
to check <br>
first there wasn't a simpler (built-in) way of doing this?<br>
<br>
Thanks,<br>
Ray<br>
