Chakavak Class 4 and 5 soft switches with unique architecture have been produced for services in different capacities from several hundred to several million. The unique architecture of soft switches includes load balancing, and redundancy. This means that in addition to being 100% stable, it also allows you to increase the number of soft switches (S / I-CSCF) in the service path, depending on your needs. All soft switches are Active-Active, which means they can respond to requests and calls. It should be noted that Chakavak is the first Iranian soft switch equipped with an online charging system.
