My manager has given me the assignment to give him the proposal of deploying the voip in our company. Therefore i need your best suggestions, so that i work on it.
Here is scenario
I am in headoffice and this office is connected to its branch office through DSL links. The bandwidth is not issue. There are nearly 7 sites. I dont want to replace PBX with Voip device, but i want to run both. In second phase i will replace all voice over ip device.
In this scenario plz suggest me the hardware and protocol that best suits, that should be cost effective also.
