Network In

Disconnecting is very rare when making calls over internet.

So with our D-Com device, that:

1, multinational corporations can set up their telecom network, which is free of charge for phone and faxing with their own network.

2, call to PSTN phones and send faxes¡£It can also connected to a phone exchange, then can have up to 8 lines with 8 difference billing accounts or one billing account, at the option of the users.

3, answering phone display at the one who is being called, so that when they call back, they will know which number to call you¡£All VOIP phone has no number now, so when you make a out-bound call, your number is hidden, and if the other side wants to call you back, they have no idea where to call you, but with our D-Com device, settings can be made to have your mobile phone number or your PSTN phone number to be as your caller ID to be displayed the one who is being called as if they think you are calling from your mobile phone or PSTN phone.

4, call diverting: so even if you are traveling abroad, you will never miss any of your calls, as it can be diverted to be answered to your any other phone that is being carried by you.

5, portable terminal: for the convince of the businessmen and businesswomen who travel a lot, we have a device which is Travelers¡¯ Babe, very small and easy to carry.

6, Plug and play: Maybe you have a subcompany in china, in Europe or any other countries, so just plug the portable D-Com device, within one minute, you will be able to make calls. No complicated settings will be needed. But in case of dynamic IP, the plus and play still is easy if you ?have a small router with you and in case that in your country IP is static, it is real plug and play.
