Voice over IP gateway VG200 was specially created for Cisco AVVID (Architecture for Voice, Video and Integrated Data) Call Manager. This device was not meant to support add-ons, such as toll bypass using H.323 protocol or SIP gateways.
Our telephone systems embrace the latest feature-rich power of internet telephony voice-over-IP technology with the carrier-grade resilience that our customers demand, allowing cheaper calls to most international destinations.
