Do You Really Need a Landline or Office Phone? (Benefits & Drawbacks)

Landlines are becoming less and less popular. You may be even wondering if landlines still exist? You should consider the benefits and drawbacks of a landline or office phone before making a decision.


  • Reliability – A landline will work under almost any condition, so you won’t have to worry about internet outages. 
  • Call Quality – Consistent call quality is still a big concern for mobile or internet phone users. For example, Verizon (the largest mobile provider in the US) only has adequate coverage over 70% of the country.  
  • Office Phone Price – Office phones are a much cheaper alternative, especially when compared to the price of the latest smartphones.

  • Long Distance Bills – Most landline services charge a premium for long-distance calling. This can be a deal-breaker if you are in contact with clients intra-state or overseas.  
  • Spam/Robo Calls – Landlines are vulnerable to telemarketers and spam callers. You can pay for specialized services to protect your business phone number, but this is an additional cost against your bottom line.  


We hope this list helps you find the best phone for your business needs.  Not all business phone systems have the functions that fit your businesses’ needs, but every item we’ve listed is a quality phone that will serve your business well.
