server recv a unrecgnized method may blocked all incoming request.

[yushimeng]

If recv a register request, but server did not found handler by method, this tx will be blocked, and server routinue blocked.

The next response will not be reponsed.

`func (srv *Server) handleRequest(req *sip.Request, tx sip.ServerTransaction) {
for _, mid := range srv.requestMiddlewares {
mid(req)
}

handler := srv.getHandler(req.Method)

if handler == nil {
	srv.log.Warn().Msg("SIP request handler not found")
	res := sip.NewResponseFromRequest(req, 405, "Method Not Allowed", nil)
	if err := srv.WriteResponse(res); err != nil {
		srv.log.Error().Msgf("respond '405 Method Not Allowed' failed: %s", err)
	}
            //. no timer trigger. or we shoud destroy this tx.
	for {
		select {
		case <-tx.Done():
			srv.log.Warn().Msgf("recv tx.Done() tx:%s", tx)
			return
		case err, ok := <-tx.Errors():
			srv.log.Warn().Msgf("recv tx.Errors() tx:%s, err:%s", tx, err)
			if !ok {
				return
			}
			srv.log.Warn().Msgf("error from SIP server transaction %s: %s", tx, err)
		}
	}
}

handler(req, tx)
if tx != nil {
	// Must be called to prevent any transaction leaks
	tx.Terminate()
}

}`

Hi @yushimeng
Thanks for reporting. This code was some leftover but never looked too much.
Anyway added a fix. We will terminate transaction. Also I am thinking this to be exported but for now leaving internally.
