Hello,
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.
Has anyone stumbled upon this kind of "SIP 481 Call leg/Transaction does
not exist" error when routing BYE messages while using topoh module?
Cheers,

Hello,
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.
On Kamailio config I have only enabled the topoh.so -module with
default options and configured this to enable masking:
modparam("topoh", "mask_callid", 1)
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:

Is this a Kamailio issue or a softphone issue on B party end?
Cheers,
