VoIP/SIP Trunk Security

VoIP/SIP Trunk Security

Data breaches have become a pressing concern for all businesses. Taking action to protect sensitive information from hackers and malware is crucial for any organization, and it's important to remember that includes IP phone systems.

VoIP/SIP Phone Systems: How They Work

Voice over IP (VoIP) phone systems make calls using the Internet rather than regular telephone lines. VoIP technologies have become popular with businesses because of the numerous advantages they offer, including the following:

  • Lower costs for overall phone service, site-to-site calling, and lease space for remote workers
  • Greater mobility options
  • Higher call quality
  • Global use of numbers
  • Integration with other applications such as online messengers
  • More convenient conference calling
  • Ability to record calls easily

Session Initiation Protocol (SIP) is a communication control protocol that's a popular choice for VoIP network infrastructures. It allows for audio and visual communication via the Internet. SIP phone service comes with a number of potential benefits for businesses. Here are just some of the reasons an organization might want to implement SIP phone services:

  • Greater reliability due to more intrinsic failover capabilities and secondary paths for data
  • Ability to increase coverage by purchasing non-local numbers
  • Better degradation and outage prevention since Internet connections are easier to monitor
  • Easy to obtain and shorter turnaround times

VoIP/SIP Trunks and IT Security

IP telephony services including VoIP and SIP phone services can become the targets of cybercriminals seeking unauthorized access to your company's data. Hackers stand to gain a lot by listening in on calls and/or getting their hands on call center information like confidential payment and account information.

It's crucial for any business using VoIP/SIP phone services to combat hacking attempts. The following strategies and solutions can protect your organization from security threats:

  • Session Border Controller (SBC), a firewall that prevents hacking
  • Virtual private network (VPN) for remote users with IP phones
  • Encryption for voice traffic (e.g., SIP over Transport Layer Security)
  • Strong voicemail inbox passwords

As hackers get smarter and find new ways to gain unauthorized access to sensitive data, it's more important than ever to protect your business from cybersecurity threats.
