Asterisk PBX Jobs

Vicidial is already live on our cloud server; what I need now is an on-site engineer in Hyderabad who can bridge it to a 32-port Dinstar GSM gateway sitting in our office. Your task is strictly configuration and testing—no fresh installs. Scope of work • Register the Dinstar gateway as a SIP trunk inside Vicidial, keeping a close eye on call-quality parameters and full compatibility with the gateway. • Analyse the current router, decide which ports must be opened, then set up forwarding so traffic reaches the cloud server cleanly. No predefined template exists, so you will determine the rules and apply them. • Run end-to-end test calls, troubleshooting the single audio problem we’ve seen so far: distorted sound. I expect clear audio on both legs before sig...

I want to deploy a voice-based AI agent that can dial prospects, speak naturally, and end every successful conversation by blocking time directly into my Google Calendar. While its core duty is simply to secure the appointment, it must also recognise and overcome the typical objections people raise on a first cold call so that only genuinely uninterested leads exit the funnel. You are free to recommend the stack—Dialogflow, Twilio Voice, ElevenLabs, Whisper, GPT or any blend that keeps latency low and speech quality high. What matters is that the agent sounds human, follows a short persuasive script, branches intelligently when an objection surfaces, then lands on the scheduling flow and writes the confirmed slot to Google Calendar through the API. When the job is complete I will b...

We need an AI receptionist that can handle incoming calls in a polite, natural, and professional manner.

In addition, the AI should be able to detect if the caller is not comfortable speaking English and smoothly switch to another language (or offer a language choice) to ensure clear and comfortable communication.

I need a reliable professional who can take over my customer service line and focus solely on answering incoming inquiries. Calls are usually straightforward questions about product availability, basic troubleshooting, and shipment status, but they set the overall tone of the brand, so every interaction must feel warm, clear, and resolved on the first attempt whenever possible. This is strictly phone support—the live chat and email channels are handled internally for now—so you should be comfortable working with a soft-phone or VoIP setup, keeping concise call notes in our CRM, and following simple escalation rules for anything you can’t solve during the first call.
