SIP Trunking is a popular option for businesses that want a budget friendly communications upgrade. SIP Trunking works by connecting your phone applications and your PBX systems for VoIP. It requires less hardware, hence the lower costs. Furthermore, the hardware reductions means that your company will have an easier time managing your business phone system. Are there any drawbacks?
The only big drawback is the potential risk involved in sending communications and data over networks. Some customers worry about fraud and unlawful listening of calls. These concerns are easily allayed with proper security protocols. Follow these tips to ensure that SIP Trunking works for your business.
Keep software and firmware up-to-date
Hackers work by discovering weak points and exploiting them. One of the best tools to combat hackers are software and firmware updates. Not only do they offer system enhancements, but they give you patches for any new security vulnerabilities.
IP address authentication
You should only permit your internal IP addresses access to your business phone system. This is the easiest way to maintain control over who gains access to the system. However, if there are mobile users that need to access the system, be sure to use custom or third-party tools that allow you to monitor log files and automatically block IP addresses if they fail a certain amount of password attempts.
Unfortunately, passwords can be relatively simple to crack for hackers. Therefore, the best thing to do is have complex passwords that you change on a regular basis.
If you have established home and satellite offices, we recommend a virtual private network for your business phone system. You could also choose to mask the access point and transmission if you use a non-standard SIP port.
Trusted SIP providers
It is also a good idea to have an IP whitelist for only trusted SIP connections. You can also allow your firewall to only accept trusted SIP providers, while refusing all others.
