Hybrid PBXs can be easily set up in countries with limited infrastructure yet offering all the functionality and flexibility you would expect from a modern phone system. Calls can be routed either via traditional PSTN networks, mobile networks or via internet, making these phone systems extremely flexible and future proof.
Hybrid IP PBX Systems require only one single network office infrastructure wiring. Calls can be routed via internet which is a great cost saver especially for overseas calls. If your company deploys a sales team, you may consider attaching a mobile gateway - as many mobile network providers like Vietel, MobiFone and Vinaphone offer cheaper rates when calling within their networks. Dialing out from your office IP phone is very straightforward: calls will be automatically routed via fixed line, mobile or internet, depending on the phone number you dial.
