Furthermore, if you wish, softphone applications may be installed and commissioned on devices of your choosing, to be used as telephone extensions within your network. By installing a softphone app on your smartphone (iPhone, Android or Windows), it can be parametrized to operate as an extension of your office. For example, we could have a rule, based on which if we call the users of such applications on their office and they fail to pick up after a predefined number of rings, we call them on their softphones. For users who are often away from their office and the trend is to always call them on their mobile number (with the appropriate charge), we could have another rule that says “try to call the user on his/her softphone extension. If the user phone or PC is within your office’s Wi-Fi network and his/her softphone application is switched on then the user will be able to pick up the call, otherwise call his/her mobile number.
In case you would like some of the softphone users to be connected to your telephony system while they are outside your office’s network (Public Internet), the said installation is proposed to be carried out on a second IP PBX, which will be virtual (Virtual PBX – vPBX) and which lies on our servers. The interconnection of this vPBX with your PBX will be done via SIP, hence you won’t have to expose your PBX to the internet, with all the risks that this implies. It goes without saying that calls between softphone users that are connected to a Wi-Fi network or between them and the office will be completely free of charge. They will also be able (if you wish to allow them), to make calls via your office telephony lines, hence their own mobile number will be concealed to the called party, who will be seeing the office number instead. In case a user is connected to the vPBX using a data plan offered by a mobile telephony operator (GSM/3G/4G) then the only cost may be for the data usage. A standard vPBX product starts with licenses for 10 users and it is renewed on a annual basis.
