I was working with Microsoft products previously and now I have changed my mind to switch to cisco networks. My company has decided to go with VOIP SOLUTION as our branches are connected with MPLS network. The project given to me is this way. I have to connect 2 sites which includes my head office and branch office to use voip (both the branches are already connected using MPLS network). My head office is having a PBX which will be integrated with voip and my branch office is not having any kind of PBX system.
Note: It will be a pilot project so please suggest a cheap hardware only for 2 sites if its approved then we will be buy good router in our head office to connect all other branches.
1) What kind of cisco routers shall I buy for both Sites ?
2) what kind of modules shall be intalled in them to start ?
3) What kind of IOS ?
4) Do I need to do something in my PBX ? for the integration in my head office ?
5) Which books do you prefer as a beginner ?
I hope the above mentioned scenario is completely transparent by any chance if you feel that i havent provided you the complete information dont hesitate to ask. Your earliest response will be appreciated.
