<p>Hello,</p>
<p>the pcap file doesn't show the BYE coming from caller to proxy.
There is only the BYE from proxy to callee. I need also the one
coming to the proxy in order to see if the required headers are
there.</p>

I'm still having this issue and now running the new Kamailio 5.0
branch. The pcap trace is attached to this email which shows the
whole sip conversation before and after topology hiding.
<br>
<br>
Has anyone stumbled upon this kind of "SIP 481 Call
leg/Transaction does not exist" error when routing BYE messages
while using topoh module?
<br>
<br>
Cheers,

I recently started testing topology hiding module on Kamailio
and encountered a problem where B party hangs up, Kamailio can't
identify the ongoing transaction to which the BYE should be
related to and instead of tearing the call down Kamailio just
sends back "481 Call leg/Transaction does not exist" to B party.
<br>
On Kamailio config I have only enabled the topoh.so -module with
default options and configured this to enable masking:
<br>
modparam("topoh", "mask_callid", 1)
<br>
<br>
Here is what the INVITE to B party looks like and the BYE
message coming from the B party:

When debugging on Kamailio end i get:
<br>
<a class="moz-txt-link-freetext" href="http://pastebin.com/raw/ZefGAz30">http://pastebin.com/raw/ZefGAz30</a>
<br>
<br>
Is this a Kamailio issue or a softphone issue on B party end?
<br>
