Model: SUNN-G800 ( 8 Ports GSM FWT )
In certain countries or regions, mobile calling rate within network (in-network) can be significant lower than between network (out-network), some carriers even offer free in-network calls. The Shawk-G8 can analyze the outgoing calls and decide to route the calls into the least cost channels, no matter it is GSM or CDMA network.
For example, in your region, you have 2 wireless carriers (GSM-A and GSM-B) operate on GSM network, and 1 carriers operate on CDMA network (CDMA-C). Phone number from GSM-A starts with 130-132, phone number from GSM-B starts with 134-139, phone number from CDMA-C starts with 133.
We can deploy two SIM cards from GSM-A on Slot 1, two SIM cards from GSM-B on slot 2, four CDMA cards from CDMA-C on slot 3 and slot 4.
When a user makes a phone call to 130xxxxxxxxx, the device will route the call automatically to carrier GSM-A.
