Smart Routing Strategy:

We always think to make easier customer needs. Routing strategy is one of the most vital part for smooth operation. V4B follows several types of routing strategy such as – 1. Priority Routing 2. Random Routing 3. Static Routing

Inter Calling Facilities:

Inexistence of HBS (Human behavior simulation) is one of the main cause for SIM blockages. We know that, all SIM uses for call termination only for outgoing & no incoming on those SIM. In this case, Machine can easily read those SIM that these are using on VoIP purpose. That’s why we synthesis HBS (Human behavior simulation) on V4B by using inter-calling system, which is very much effective to reduce your SIM block.

SIM Protection:

It’s a million dollar question for all non-cli users “How to stop SIM blocking”. Truly speaking, there is no solution in this world which can 100% stop your SIM blocking. But we are the first in this sector that we implement a different kinds of logic on V4B to protect your SIM like; minimum & maximum digit to call, max attempt of number in minutes and hour, controlling call duration limit & many more.

Fake call Detection:

It’s a big thought “How to avoid fake calls” because fake calls is one of the most serious case for SIM blockages. We would like to announce that V4B is able to perfectly avoid fake calls. Its call filtering technology will make sure you to get safe calls so that SIM blockage will reduce.

The speed for your WAN network will be the aggregate of the Internet access lines plugged into the V4B. As a result, you will get faster connectivity than previous condition.
