<p>Hello,</p>
<p>are the other headers (Via, Record-Route) handled by the topos
module for OPTIONS request? Is only Contact header left?</p>
<p>Regarding topoh: there can be some enhancements to try to shorten
the size of those values, from what I know, short text compressing
can get 20-30% compression rate, but not always and I am not sure
will actually help with those SBCes. Have you able to figure out
the size of the header values when they fail to handle the sip
messages?<br>
</p>
<p>On the other hand, I am eager to see how those SBC are going to
do when STIR/SHAKEN is added (soon by US/North America carriers),
the Identity header is quite large...</p>
<p>Cheers,<br>
Daniel<br>

<div>Hello,</div>
<div> </div>
<div>I just realisied I made a mistake and send this reply to
the wrong mail address.</div>
<div> </div>
<div>
<div>The OPTIONS are keepalive-request and out-of-dialog. So
topos is not able to manage these?</div>
<div> </div>
<div>I also tried topoh. Topoh was able to mask the contact
header even in out-of-dialog OPTIONS. </div>
<div>The main reason to switch to topos is the
line=sr-parameter. Some calls got a very long
line=sr-parameter which lead to problems with different SBC
vendors.</div>

<p>Hello,</p>
<p>the module aimed at supporting topology
hiding for calls. Is the OPTIONS part of a
dialog or out-of-dialog (like a keepalive
request)?</p>

<div>I have a problem with the topos
