1. Types of VoIP devices, pros and cons


There are 7 types of VoIP devices:


1) IP phones with a wired handset and a wired network connection
(Grandstream GXP, Panasonic KX-HDTV, Fanvil X, Yealink SIP-T, etc.)



Pros:


  1. The most reliable of all types of VoIP equipment
  2. They rarely fail, no intermediate equipment is required to connect to sip (besides the router, of course), they are connected to the network by wire, powered by electricity (hence, they do not require batteries). Due to these factors, these devices stably keep sip registration, have good communication quality and long service life.
  3. Easy to set up
  4. Easy to connect
  5. Ideal for a call center and technical support, as it is possible to connect a professional headset (depending on model)

In any case, I would better recommend opensource CSipSimple . You can download the installer on the Internet. It is easily configured, it works amazingly.


That's all.
