Complete voip solution Telecom

We do what we want ? We we want to the best of our knowledge. We don't know about us, please tell you. Direct us. We want a complete Telecom solution. So in asterisk that can do everything we want. For example, centos + asterisk + php + nginx + mysql + a2billing + freepbx multi-tenant and other service components to the server must be established. To run mysql on a separate server for the web site hosting services on the server will work on a backup basis. Asterisk on a separate server and other services will work on a backup basis. we're thinking of using VMware ESX virtualization software. At the same time security is very important for us. We want to know suggestions and what you can do about security. For example, VPN with SMS authentication entered entries or double. The software can only be used by us that will allow you to security measures need to be taken. So, another person unauthorized use of the software. We need to be able to communicate to the server as the script and ISO software. Of our work is 100% solid, we want to make. For example, the data base will be located on two different servers and the same information is supposed to be there. So made redundant. On the asterisk side in the same way, we want a redundant structure. In terms of VoIP services, there should not be an interruption in service. We work with a global Tier 4 certified data centers. So continuity is very important to us. The following is my personal opinion on redundancy and security. E5 cpu + ram RAID 10 hard drive 4 nvme ssd 64 GB 7 Centos + cpanel + dns and MySQL cluster + cdn + cloudflare security. The SRV record. The closest location geographically (MS ping) the Asterisk server provide quality service to the customer. Other routines use Trunk routes, in case of failure. And we want to use the cheapest route. iphone + android + mac + Windows voip we can think later of their software. But we can evaluate the proposals. The colors of the site design website design VoIP with the drawing visually the same, and it must be very beautiful. For example, blue and light gray colors and other compatible primary colors, sub-colors. For example, graphical Dashboard screens of the graphic display of the report and the CDR is supposed to be good a lot. Changing the menu position that we see as unnecessary of removing unused features. We want a responsive design. Whmcs automation software do I need to use ? if you need whmcs to be integrated into the system and eat all we want. Did we want the integration to be performed from the service providers api. Customers before they reach us easily via PayPal, Credit Card payment services such as we want to load balance automatically using.
