DYL has been a huge benefit to our agency. However the software has its issues like any other. The DYL app has now been unavailable for over a month no which does interfere with our business when we are away from the office and we need to still be able to manage the phones. I did have a rep provide me with an alternative solution which was Zoiper and that app is a complete and utter mess and not very reliable. So needless to say when and if they can get the kinks worked out with the DYL app I will then be very pleased with the product.
