build a voip system

Hi, I have 7 years of experience in this field. I can do this for you. Please check my feedback and portfolio. Let me know when we can discuss further. Thank vivek

Hello, My bid is for installing Asterisk and FreePBX with A2Billing as per your project requirement. However, if you are looking for more scalable solution with more advanced Billing Solution I would recommend you consider a solution based on Freeswitch which I can also provide. If you are looking for a Mult-tenant PBX solution you are NOT going to get that with Asterisk or FreePBX. With regards to the Billing Solution that I recommend take a look at cgrtbilling dot com. I am happy to discuss with you further to ensure that you get the best solution for your business.

hello, if asterisk is not needed compulsory, i can help you to get better pbx system.. i recommend 2600hz kazoo.. it is cluster ready, freeswitch,kamailio, couchdb. rabbitmq, Erlang based. it have great PBX interface and backend datastore interface to manage everything.. thanks mohammad

Dear Sir/ Madam, My name is Henry from PHAMTECH Co. My team is interested in this project as it is exactly within our scope of expertise: We are an 8-year experienced web/ app design and programming group. We are located in Hochiminh city, Vietnam – where most of the high quality software in the world is being produced. I understand that you might just look for a low cost product now. With your listed budget and the kind of requirements, we can only expect some quick work probably from part-time freelancers. It may serve well as a demo purpose. However, if you are really serious about software and determined to have a genuine piece which can serve several hundreds OR thousands of users concurrently, having strong codebase and smart UI with high expandability, or you simply need a professional IT team to back and run your app behind your business, please consider hiring PHAMTECH. Walmart’s Mobile, Toyota Asia, Verizon Wireless and IKEA are among our featured long term partners. You could always visit our website PHAMTECH to learn more about the works and the happy clients we're behind.

Hello! Now, I made and manage the system like you described. This system include 3 servers with asterisk, 1 server with asterisk+a2billing. Asterisk servers have no web-interface (because I no need it - I manage all via .conf-files and phpMyAdmin), but have cdr-based statistic with call-records. If needs I can install interface for my asterisk in any moment, but me no need it. Each of asterisk are connected via sip-trunk to a2billing. At a2billing I have some trunks to diferent providers. Today, this system serve 5 companies. (3 on one of asterisk-server and 2 on other). Admins from this companies have access to a2biling customers interface. They can watch statistic of calls, who made call (name of device or user from asterisk) and simulate call. All of them installed and configured by me. Without any help from other users. If I will have a client who needs management interface, I wiil setup virtual server with any of interfaces like elastix, freepbx etc.. As you can see, I have some experience in building systems like desired. If you want, we can talk in chat about system witch you need. If you tell me more about desire system, I can tell you how it I see and what I can to do. And after that, you can make you choose. Best regards, Andrii. P.S. Yes, I have some ideas about how make system which will manage via web-interface, but I don't can make interface, I can only build all system and say how to built interface. Or how to make system you needs with opensourse programs.
