Ideally, you want the call quality over VoIP to exceed that of traditional landlines. This is achievable but it depends on a number of things such as broadband connection, bandwidth, hardware and VoIP provider.
VoIP technology may not be as robust as canada whatsapp number data PSTN. This is because the data is compressed and split into transferable ‘voice packets’ to be sent and these then have to be ‘unpacked’ at the other end.

This can manifest itself as echo, delay or latency.
Total reliance on your broadband connection

This can be catastrophic for a business. Some service providers will offer a backup facility or you may want to install a spare broadband line that acts as an emergency fall-back.
