Hi,

I would start with tcpdump or ngrep for basic is ip a to ip b communicating. Because if the sip request is broken or not correct responded or whatever sngrep didn't shows all on the wire in such cases.

Sngrep is great for "its working and I want to see dialogs" imho, not for fundamental network problems.

Cheers Karsten

Hi

I’d start with sngrep so establish if it’s not receiving the BYE (client/network/nat/firewall/etc issue) or not kamailio is not seeing the BYE.
