public void processTimeout(TimeoutEvent transactionTimeOutEvent) {
    Transaction transaction;
    if (transactionTimeOutEvent.isServerTransaction()) {
        transaction = transactionTimeOutEvent.getServerTransaction();
    } else {

    }
    Request request = transaction.getRequest();
    if (request.getMethod().equals(Request.REGISTER)) {
        registerProcessing.processTimeout(transaction, request);
    } else if (request.getMethod().equals(Request.INVITE)) {
        callProcessing.processTimeout(transaction, request);
    } else {
    // Just show an error for now
    }
}
