Will this product help my network if I have only one internet circuit?
SD-WAN is designed to optimize traffic to the best route. If you only one circuit then all traffic will traverse through the one circuit thus not helping the network traffic as the data is restricted to one pathway.
Will CallTower provide services to manage my firewall along with SD-WAN:
No, as the router device sits outside the customer’s firewall the customer will have responsibility to manager their own firewall and security settings.
Will CallTower provide support for the SD-WAN device?
All the devices CallTower sells we also support. Our support is 24/7/365.
