    I need to install Asterisk on a server, use mysql as my database, and customize the set up with PHP. I need it in PHP because i will customize it further with my inhouse PHP staff. I have many DID numbers, IVRs, and extensions for at least 10 businesses. However i need to record and display the call recording info separately for each business. Each business has its own DID number and inbound route. Im wondering if it is possible to run some software that transcribes all the calls and sends them to my email. also and scans for keywords, such as "speak to the manager" "i want a refund" "there are errors on my file" or anything else that would be of importance to me. Currently my voice mail is non existent, i need the voice mails to get sent to custom servi...

    I need a developer who can create a WebRTC server using Janus or FreeSWITCH. We have a system that works in two ways: 1(attached graphic). Calls will come in through our DID. Each call is authenticated through our API (handled by a separate developer) and then each user is placed into separate channels after API authentication. The audio stream from the caller will be listened to and processed by our audio tools. The calling system is setup through Twilio SIP trunking. 2. When each user is in a webrtc channel, allow for the ability to have one or two users join via webrtc clients such as our mobile app, browser, etc. (another developer will handle client development). We are NOT building a conferencing app, but we need the ability to accept calls and then later perhaps have a client j...

    Do you think it is possible when someone it using the phone to send 1. to send information to a listing device on the receiver of the call without an audible tone? If that will not work is it possible to 2. send touch tone input for the caller and have a device on the receiver side pick it up. I hoped I explained this. If not send me questions that you have. Thanks Tom
