Removing high cost barriers
Building carrier applications with Asterisk on off-the-shelf Linux servers is intriguing as it removes the high initial cost barriers of SS7 connectivity. This allows a startup VoIP service provider to build SS7 Interconnect by beginning with small-scale gateways with a only few SS7 E1s and to gradually expand with growing traffic. Linux and Open Source guarantee that the provider is not locked into a proprietary solution with unpredictable future risks and costs.
Low Risk
The low initial cost makes the solution virtually void of risk. High initial investments are unnecessary, you ‘pay as you go’.
