<p>Hello,</p>
<p>check your configuration for 481, afaik, kamailio tm module
doesn't send the 481, that's why I expected to see two BYEs, but
there is only one. Maybe the 481 is sent from kamailio.cfg by your
routing logic there.</p>
<p>Cheers,<br>

<p>Hello,</p>
<p>The B party (IP: 37.219.148.155) is the one that sends the bye.
A party (IP: 178.75.176.146) will never see this bye because
Kamailio (IP: 193.28.89.162) in the middle replies to B party
with 481. The result is that A partys softphone thinks the call
is still online.<br>
</p>
<p>This can be seen on the kamailio_5-0_sip481.pcap trace.<br>

<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, <br>

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: <br>
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://pastebin.com/raw/f63zUmid">http://pastebin.com/raw/f63zUmid</a>
<br>
<br>
When debugging on Kamailio end i get: <br>
<a moz-do-not-send="true" 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>
<br>
Cheers, <br>
