Digium and Ranch Networks Team to Make Asterisk the Most Secure and Scalable VoIP Solution

Digium and Ranch Networks Team to Make Asterisk the Most Secure and Scalable VoIP Solution

Security Code Now Available to the Asterisk Community

Huntsville, AL and Morganville, NJ — January 24, 2006 — Digium, the original creator of Asterisk and pioneer of open source telephony, and Ranch Networks, the first IP telephony network appliance provider to integrate security and bandwidth control for IP-based applications, today introduced its security code for the Asterisk open source IP telephony platform. When combining Asterisk with Ranch Networks new RN series appliances, the solution provides unprecedented security and scalability to the open source telephony industry. The code is available for download at and

Ranch Networks solves the problems associated with VoIP implementations through both its MIDCOM integration with the Asterisk platform, and several of its Patent-Pending technologies. The MIDCOM integration provides for dynamic per-call firewall control, bandwidth management, NAT traversal, and RTP traffic bridging — all supporting encrypted signaling streams, while the Patent-Pending technologies separate voice, video, and data traffic into multiple, secure zones without having to reconfigure IP addresses.

“Security is potentially an issue for SIP deployments since ports need to remain open at all times in order to enable voice traffic–leaving potential open doors for intruders,” said Mark Spencer, president of Digium and creator of Asterisk. “In providing this technology, we are proactively addressing the security of VoIP before it becomes a major concern, while also providing quality of service and increased scalability.”

Ranch Networks’ technology sends instructions to the firewall to open the ports on an as needed basis. Media streams can flow from one phone to another, then close ports when the call is terminated. Instructions are also sent to the appliance determining the amount of bandwidth needed. As calls come in, data is shrunk to allow necessary bandwidth on a protocol basis. Ranch Networks guarantees that voice is given priority over data. This technology supports multiple phones behind any number of firewalls.

“We expect this will change the mindset of large enterprises and service providers that were previously skeptical of VoIP and open source technologies, to look more closely at the customization, flexibility and huge costs savings that a platform like Asterisk provides,” said Ram Ayyakad, founder and CEO of Ranch Networks. “We have eliminated any security and scalability issues that could be argued by proprietary vendors.”

The Ranch Networks security code has received the highest certification through ICSA.
The security code is available by the download of Asterisk 1.2.2 and is available for download from and
