On-chain International Calling

This can be a game changer for the small business because they have a hardware WAN phone also. They provide a US number and the user chose the area code of their own while using the service for the first time. In us the call rate is 0.02$ per mininute and traditional services gives 0.7-0.8$ rate.

I have personally used this service and I found it awesome and it gives us a wonderful alternative in web3 space. I also highly recommend to read this article: https://ecency.com/hive-167922/@austinbiswas/blockchain-intergrated-calling-system-usdbbp?referral=eearning
