    VOIP IVR System Needed 6 days left
    VERIFIED

    We need VOIP based IVR system. We need IVR system hosted on cloud with custom IVR options based on the Called ID. Below is the basic flow: 1. Customer calls to our Customer Care 2. Our Cloud Hosted IVR will receive the inbound call and start to play a Greeting Message 3. In the mean time while playing the Greeting message, the system will consume the Restful API exposed from our CRM. 4. In the API it will pass the caller number and our system will return the Welcome message to be played and the IVR menu options to be provided to the caller. 5. Please note that the IVR menu options will be different and dynamically generated based on the caller ID. So our API will either return the dynamic options in text form and the IVR system will convert from text to audio. Or our API can also return the IVR Menu ID, based on IVR menu ID, the IVR system will play that specific IVR to the caller. What we need: 1. The cheap and best Cloud IVR hosting. We are based in India 2. There should be provision to modify the IVR design code 3. The pricing plan should be - Pay per call. 4. Our monthly inbound calls will be approx 500 to 1000 calls per month

    Hi Murugan P. My name is Greg Daley. I'm a musician, former programmer and online teacher. I also have an audio engineering degree. I need help with one very quick project. I'm sure you are familiar with the demo [url removed, login to view] which I have been using to teach with. Open source on hi thumb. VoiP apps like Skype are completely inadequate for my use due to low audio quality. For a quick need, I just need modifications of the demo app to include a very simple screen share ability and for it to be a bit more robust for Mac (Safari). There are difficulties with permission sometimes with access to mic and Webcam. I have been using it with url parameters at 48000Hz and HD video. Works great with these settings with very tolerable latency. Long term, I want to co-author commercial software with webrtc for musicians and teachers that need high frequency range audio. webrtc is going to be the technology for this and I will have no problem marketing a finished product here in the US. Perhaps a teaching platform based on the software. Ultimately with perhaps [url removed, login to view] and c++ I would tackle the initial project myself if I were not so late in discovering RTC. Anyway, I am in a great need for the initial work. I prefer to be contacted by phone. Best Regards, Greg Daley South Portland, Maine [REMOVED BY [url removed, login to view] ADMIN]

    Hello, We need to develop a SIP to Viber/Whatsapp gateway. The gateway should be able to pass voice calls incoming over SIP and forward them through Viber/whatsapp to complete the call to the called party number. The devolpment should run under GNU/linux (Asterisk,etc). The implementation should return the correct call error codes to the SIP backend, i.e. CALL SUCCESS, BUSY, UNAVAILABLE, etc. For a successful project we'll select the one, triggering successfully continuous SIP/Viber calls. Functional flow 1) Calls originating will send to Viber/whatsapp gateway 2) Viber/whatsapp gateway converts the sip/iax signal to viber protocol 3) the termination number carried from the origination header will be checked by the Viber gateway , if the number is used by Viber/whatsapp and if the number is online, the call will terminated on Viber/whatsapp!. 4) if the number is not used in VIber/Whatsapp it sends 503 error and rerouted to other gateways .
