why choose voip telephone services vs regular?

what advantages and disadvantages do they have?

PRO:
cost - almost always it is cheaper to implement a VoIP system than a traditional POTS telephone system.. the recuring monthly costs are also always cheaper, and normally are what the advertised or up front price says because many of the taxes and fees that are associated with POTS do not apply to VoIP..

features - it is much easier for carriers to implement new features, such as voicemail to email, or text..

portability - you can bring your IP phone, or ATA with you wherever you have internet access and use the same phone number pretty much anywhere in the world

OPX - it is cheaper and easier to implement an off premise extension than with POTS and an analog PBX

CONS:
requires AC power - in the event of a power outage, your VoIP service will not work with out the addition of back up power for your VoIP phone, or adapter, and your network equipment - most battery backups only supply sufficient time to back up and shut down your computer systems, and can not sustain prolonged power...

requires high speed internet - not only is the speed of the internet a factor, but the latency and jitter are also contributing factors, the more lines that you add, the more bandwidth that is going to be required for your VoIP service - for larger companies it would be recommended to maintain a separate network for VoIP and for computer networks..

single point of failure - since VoIP relies on the internet to work, if the internet goes down so do ALL of the phone lines. This is an extremely rare for traditional POTS service, normally with landline service you might lose one or two lines, but still be able to function with the remaining lines going to your business... to reduce the effects of this single point of failure, multiple internet services - preferably from different technologies (DSL, cable, FTTH) should be connected to a multi WAN router, which provided redundancy in the event that one internet connection goes down...
