We install solutions such as Cisco PGW2200 and other SS7 C7 solutions for VOIP worldwide.
Why do you need SS7 or C7? The traditional PSTN switches use SS7 & C7 signaling internally & the switch operators have to spend money on conversion cards and software to hand off to you ISDN signalling to E1 & T1 circuits. We provide your with full network diagrams/designs before you decide to purchase any of our products. We guarantee the lowest prices and warranty all parts & labor for one year. We will install your equipment anywhere worldwide.
