When thinking about quality, it’s easy to assume SIP phones will always work as they did from the beginning. After all, there are no moving parts and most of the features are software-based.
However, everyday wear and tear takes a toll from phones falling off the desk, coffee spills, power spikes, electronic failures, etc. Warranty coverage is an important consideration. When considering SIP phones, the longer the warranty coverage, the better. Also look for warranties with advanced product replacement, which means the manufacturer quickly sends a new (not refurbished) replacement phone the minute it’s needed.
