We are doing VOIP retail business in UAE and Oman (VOIP ports are blocked in these regions), We are using VOIPSWITCH ([url removed, login to view]) as our softswitch and also using it's server/client bas tunneling technology to bypass port blocking issues.
Biggest limitation with this solution is customer must 've a PC on which tunnel client has to be running all the time to let customer use his ATA/IP Phone. We need this process to be Plug and Play.
Project requirement is similar to [url removed, login to view] Based upon L2TP or similar technologies we need some kind of solution that will work with our existing softswitch i-e; VOIPSWITCH, to make any kind of ATA / IP Phone device truely P&P.
Main goal of the project is to bypass port blocking issues, and making ATA / IP Phone devices to work in Plug & Play Mode.
Please do not hesitate to ask any question that you might have..
