Delivering voice and multimedia over an IP network saves businesses time and money, while keeping security and QoS top of mind. But, just like any other investment, the time will come where your VoIP phone system will eventually need some tune-ups (after all, nothing ever works 100 percent of the time).
Innumerous tools exist today for protecting and maintaining the integrity of VoIP phone systems, but that doesn’t mean they are all equally reliable. Just as you shouldn’t go to any mechanic to look under your hood when your “check engine” light appears, you shouldn’t employ just any monitoring or analyzing tool when network performance staggers.
Without a doubt, Wireshark is emerging as a renowned network analyzing tool trusted among leading network professionals, security experts and developers. It's gaining momentum among the IT industry as a mainstay for network troubleshooting and optimization.
Here’s why you should consider making Wireshark a VoIP business essential:
- It’s free to use: As an open-source project, it is completely free to use. In other words, you can download the software without ever having to pay a license fee. As noted on their website, this free software isn’t a demo or free trial—it’s the full version of the software.
- Virtually anyone can use it: As an open-source project, it is the product of a community of collaborators and contributors. With an expansive Q&A section on its site, anyone committed enough can familiarize themselves with the tool. This may be particularly helpful for small businesses without a robust IT department.
- It’s compatible with almost all computing platforms: It lets users “capture and interactively browse” live traffic from computing platforms including Windows, OS X, Linus and UNIX.
- It allows you to monitor data directly at the packet level: There’s no better way to analyze network activity and patterns than by monitoring at the packet level. According to its website, Wireshark can read live data from Ethernet, Token-Ring, FDDI, serial (PPP and SLIP), 802.11 wireless LAN, ATM connections, and any device supported on Linux by recent versions of libpcap. It can also read data from a number of capture file formats (you can view the entire list here).
