Get Securing Cisco Ip Telephony Networks

Using VoIP internally is as secure as traditional phone lines, as long as the internal IT infrastructure is secure. The calls are being made within an internal system so external hackers cannot easily intercept the data. However, when calls are made outside the internal infrastructure, they are vulnerable.

IP Telephony utilizes the VoIP standards to create a telephony system where higher level features such as advanced call routing, voice mail, contact centers, etc., can be utilized. Session Initiation Protocol (SIP) is a peer-to-peer, multimedia signaling protocol developed in the IETF.

Difficulties with VoIP Common issues that can happen during calls are delays, noise and echo. Bandwidth dependency - VoIP depends on your internet connection. If your connection goes down, so does your phone line. Similarly, insufficient bandwidth will likely cause quality issues with the service.

Every VoIP call has traceable elements, which allow you to trace them yourself. This includes: Caller ID: Caller ID helps trace a VoIP call by providing the caller's number or username. However, some callers may hide or spoof their Caller ID, making it less reliable.

VoIP (Voice over Internet Protocol) can be secure if properly configured and if security best practices are followed. However, it is not inherently immune to security threats. Running VoIP through a router can introduce security risks like any other internet-connected device.

The only way VoIP communications can be traced and captured is by law enforcement. Law enforcement required constitutional elements like warrants to trace phone calls. This type of tracking can only be done by a legally authorized interception system located at an ISP.

Employ a Virtual Private Network (VPN) Using a VPN can add an extra layer of security to your VoIP calls. A VPN encrypts all your internet traffic, including VoIP data, and routes it through secure servers, making it more challenging for attackers to intercept and decipher your communications.

Cisco Unified Communications Manager Release 8.5(1) and later includes Security by default, which provides the following security features for Cisco IP Phones without running the CTL client: Signing of the phone configuration files. Phone configuration file encryption.
