And more...
-As we know the conversations between subscribers of a PBX are free (e.g. conversations between co-workers in an office). In standard PBX to make this possible, it is necessary for telephone cord to exist physically from the PBX to each device. In other words – the standard PBX use telephone lines as a medium for voice transmission. Software PBXs use local or global network as a medium for voice transmission. Hence their main advantage – subscribers of such a PBX are not limited by distance – they may be located in any point of the world where there is Internet.
-If you have to move your office and you have IP PBX, you will be able to keep your known telephone numbers, without a request and having to wait for “technical availability”. In most cases it will not even require PBX reprogramming. This is true even if you move to another city.
-The software PBX capacity is virtually unlimited – adding new account is made by PBX programming. No need for any hardware. (In conventional PBXs to increase the number of accounts you needed to add boards and often it turns out that the maximum capacity is reached and the PBX can no longer expand, and must be replaced).
