zeabix IP-PBX and IP-Call Center Editions are able to be integrated with your existing network infrastructure. However, some configurations might need to be revised e.g. VLAN, Routing and Quality of Sevice (QoS). This to ensure that the system is able to deliver highest quality without any issues. At zeabix, we have 10-year experience Network Engineers who are certified with Cisco Systems. We are willing to suggest and help your organization to integrate our system to your infrastructure with best practice.
