We are doing VOIP business in VOIP blocked regions, Middle East mainly. VOIP is blocked here , we 've VOIP soft phone and other applications for our customers. What we need is to 've Secure VPN which can do the following
1:- Backend VPN server will listen all VPN requests and entertain them. It should forward all voice traffic to our Softswitch.
2:- Clint application must be very Simple, either it connects automatically on windows logon, or client 've to double click on Desktop shortcut. And this client must not ask any password or other details and RECONNECT AUTOMATICALLY in case of disconnection due to any cause.
3:- PPTP , Openvpn and L2TP are not best options, as
We can not connect so many connections on PPTP, in this case ISP will block that IP
L2TP they easily trace and block
OpenVpn they blocked fully.
What other choices you 've ? IPSec ? or what ?
Innovative ideas are welcome , the most important thing to follow is , how to facilitate customers, so either they just install and all the time VPN connect itself or they click once windows logon and keep using our voip softwares.
Please come up with your detail proposal. i-e; what VPN / Tunneling technology you will use and how client will connect.
Many Thanks and Regards,
