When Drachtio receives an INVITE with Session-Expires header that does not include a refresher parameter, there is no Session-Expires inserted on the 200 OK and no session timer set up.
The RFC states that the UAS MUST respond to the request for Session timer. The refresher options for the response are noted: https://www.rfc-editor.org/rfc/rfc4028.html#page-15

I think this is the role of the drachtio-srf app
