ShoreTel Phone System vs Cisco Phone System

 As both a ShoreTel Certified VoIP Engineer and a Cisco CCNA (Voice) I got an good opportunity to design,configure and install VoIP network for many clients. One of the questions that is most asked of me is "Which one is better?"
It depends on few factors.
Whenever VOIP is chosen to implement, the good design, planning and maintenance have to be concerned and you can have good Unified Communication System.
