A BYE ~30s after the ACK usually means the ACK was not accepted or associated with the call. This is usually due to some problem with the ACK. The ACK responses must be built according to specific requirements based on the INVITE and 200 OK values, so it is not possible to say for sure whether there is anything wrong with the ACK with only the ACK and BYE.
