Cisco and telephone
during 1990s Cisco acquired more than a company that had been working closely with Voice over IP protocol leading to its first VoIP product called Internet Telephone System (ITS) which was an IOS based soft PBX that run on top of Cisco routers (1800 Series, 2800 series, etc..) but this product was mainly targeting SMB, it was now the time for Selsius System acquisition in 1998 for Call Manager which started as Video conferencing product and later transition to be soft PBX, Cisco Developed both products and changed the ITS name to call manager express and lately Cisco changed both product names (CME became CUCME, CCM became CUCM) adding Cisco Unified in front of each product name.?
Cisco Education
Cisco has put a lot of efforts on product marketing and customer education and developed the most stable and desired certification in IT field , Cisco Career Certification now have five different levels Entry, Associate, Professional, Expert and Architect for Eight different Paths which include Routing & Switching, Voice, Security, Wireless, Design, Storage Networking, Service Provider, and Service Provider Operations.?
I have nothing against Cisco, in fact when I graduated from University as Communication Engineer and although I know a little about Networking I knew that there is a company called Cisco, I love the company, their marketing and education strategies. The company is very strong with good vision and wise acquisitions but it’s not a company of innovation as we have seen with Avaya. they Just buy a company with their products and Talents and then only direct the development of that product and they mainly work on Marketing and Education. and this is not enough to compete against Avaya; At least in IP Telephone Market?

The Cisco Eduacation and Certifications is what pushes so many compnays to use there products. It makes it easier to find qualified tech to install and upgrade their systems.
