I am using the topoh module and it works fine except for the BYE requests coming from the callee (the person receiving the call).  When a BYE is received from the destination of the call, then Kamailio relays it to the dummy IP 127.0.0.8.  This is exemplified in the topoh:msg-outgoing and topoh:msg-sending events where the $sndto(ip) is set to 127.0.0.8.

I am using all default modparams with topoh.  The only modparam I have is for setting the event_callback.  I am using Kamailio 5.6.2 with Kemi using python3.
