The connection is behind CGNAT, meaning I do not have a real public IP. I am looking for an expert to provide a solution to get a Dedicated Static Public IP so I can remotely access my internal network (Router management, SIP devices, etc.) using my noip DDNS Conditions: I cannot upgrade to a Business SIM card. I do not want to run a local PC 24/7 as a bridge. I just need a working Static IP solution that routes traffic from the outside directly into my local network. Please propose your method and how we can implement i
I need an expert who knows the Panasonic KX-NS100 inside out to take over ongoing maintenance and, more urgently, to hunt down stubborn routing problems. At the moment we are plagued by ghost calls, fake trunk activity and sporadic audio drop-outs that confuse users and clog the logs. These symptoms point to deeper call-routing faults, so I’m looking for someone who can dive straight into ARS tables, COS settings, SIP trunk parameters and firmware quirks to pin down the real cause, clean it up and stop the phantom traffic for good. You’ll be given remote access via VPN or TeamViewer during our business hours so you can trace packets, watch live call traffic and adjust the configuration in real time. Once the issues are eliminated I’d like concise documentation of every...
Require is a custom Asterisk-based autodialer engineered for high-volume, unregulated outbound traffic. The system must run on a hardened Linux distribution (e.g., Debian or CentOS) with Asterisk 18 or 20 compiled with specific modules: chansip for SIP trunking, appdial for call routing, and app_playback for IVR management. The core architecture includes a predictive dialing engine built in Python or C++ that interacts with Asterisk via AGI (Asterisk Gateway Interface). It must integrate the sofia or chansip channel driver to handle SIP trunks, supporting multiple concurrent legs for rapid call placement. For DTMF handling, the system will utilize the appdial with D option to detect dual-tone multi-frequency signals, routing them to specific IVR branches defined in extensions.conf. The I...
YOU MUST BE FROM THE PHILIPPINES TO APPLY! Pay is $4/hour. Only respond if you agree to this pay rate. I run a small U.S.-based operation that needs hands-on help with day-to-day customer interactions. I receive a steady flow of inbound calls and emails, plus occasional outbound follow-ups, and I want every contact handled promptly and professionally. During that three-hour window you will: • answer incoming calls and place quick outbound callbacks when required, • reply to customer emails in a friendly, concise tone, and • keep our live-chat widget active so no visitor waits more than a minute. A rock-solid, high-speed internet connection is essential—dropped calls or slow chat responses won’t work for us. I currently forward calls through a VoIP line...
I need to setup a VPS ready and Home Assistant. My next step is to add a rock-solid MQTT layer so I can trigger relay modules through voice commands issued from Amazon Alexa, Google Assistant, and Apple Siri. The relays must respond to simple ON/OFF requests and support dimming where hardware allows. Here’s what I need you to handle: • Recommend and install a production-grade MQTT broker on the VPS, configure secure remote access (SSL/TLS and user auth) and verify message flow with Home Assistant. • Create the necessary automations/intents inside Home Assistant so each of the three assistants recognises the devices and exposes the ON/OFF plus dimming capabilities. • Supply clean, well-commented Arduino (ESP32) code that subscribes to the chosen topics and drives ...

Hi, I'm looking for someone to build a sip soft phone that has no dialer for outbound calls. It will only receive incoming calls.

My existing Plivo account is locked and every attempt to register a fresh one—whether with Gmail or another address—has been rejected automatically. I need a working, fully-verified Plivo account plus the email inbox that is tied to it, so I can manage both credentials myself. What I tried: I already attempted registering with a non-Gmail address and Plivo still denied the signup, so the usual work-arounds are exhausted on my side. Here’s what I need from you: • Create a brand-new Plivo account that passes Plivo’s phone/SMS and email verification steps. • Register it with an email service that reliably receives Plivo messages (any reputable provider is fine as long as it works). • Hand over the login credentials for both Plivo and the new emai...
I am looking for an experienced telecom/Android developer who can capture the live voice stream (two-way audio) of an active GSM (cellular) phone call. Requirements: Capture the live GSM call voice packets/audio stream. Access both incoming and outgoing audio during the call. Provide a technical approach for capturing the live voice stream. Explain any limitations or device-specific requirements. Share proof of concept or previous experience with similar work, if available. Please apply only if you have experience with GSM telephony, mobile voice processing, or low-level telecom/audio systems.
I need a proactive telecaller who can fluently speak Tamil to reach out to my existing customers and remind them to complete their KYC. All contacts are current clients, so the tone must remain courteous and service-oriented rather than sales-driven. For every call, I’ll provide the customer list and a short script outlining the key KYC points to cover. After each interaction, you’ll log the outcome—completed, follow-up required, or unreachable—into a simple Excel spreadsheet I supply. Accuracy in that sheet is essential because it feeds directly into our internal compliance reports. You should have a quiet calling environment, your own phone or VoIP setup, and the confidence to handle basic customer questions about the KYC process (I’ll brief you on the co...
