Description

we are using version: kamailio 5.5.1 (x86_64/linux) 8aa8df-dirty and we have a setup with 2 kamailio instances. First one is doing topoh, and the second one is supposed to not do it

Despite this we do see that some replies the second instance is masking some headers like record route and contact in the 200ok (not in the 180)
Besides, seems that when the b-side sends a BYE, kamailio show an error, see in logs part
However, in the sip pcap we do see thre BYE like it should be. At least that's what it seems to me
i attach you the trace
topoh_bye_bad_message.txt

do you have any idea of what can be the issue?
