I need a fully-functional auto dialer built for my company and I want it up and running fast. The core requirement is seamless VoIP ser...with the VoIP provider I’ll share once we start, including proper authentication and fail-over handling. • A clean, web-based interface where agents can log in, see their queue, and record basic call outcomes. • All source code plus clear deployment and user documentation so my in-house tech team can maintain it afterward. If you’ve built dialers before—especially with Twilio, Asterisk, FreeSWITCH, or similar stacks—let me know what framework you recommend, the timeline you can commit to, and any additional features you can add (call recording, automated messages, analytics, etc.). I’m ready to move q...

I have a fresh Linux server ready and need the latest stable release of FreeSWITCH installed, secured, and connected to my SignalWire space. Beyond a plain install, I also want the common advanced pieces in place—proper codec support (Opus, G.729, etc.), a clean dialplan template I can extend, and any SIP profiles necessary for SignalWire’s endpoints. Once the service is up, please register it to SignalWire, verify inbound and outbound calling, and leave me with clear notes on anything customised (modules enabled, directory changes, CLI commands). Deliverables • FreeSWITCH latest stable compiled or packaged and running on my Linux server • Advanced configuration applied: codecs loaded, base dialplan, SIP/TLS where applicable • SignalWire c...

I have a brand-new Debian box that is still factory-fresh, and I want it running a clean, production-ready FreeSWITCH instance that’s already talking smoothly to SignalWire. My immediate priorities are: • Compile or package-install the latest stable FreeSWITCH build on Debian • Enable and test the Conference calling module (no voicemail or faxing required) • Perform all network and SIP/WebSocket configurations so the server registers with my SignalWire space, routes calls correctly, and survives reboots I’ll need you to handle the firewall rules, TLS certs, and any NAT or port-forward tweaks along the way, then document what you’ve changed so I can keep it maintained. A short test plan proving inbound and outbound conference calls thro...

...(SEE ATTACHED IMAGE FOR MORE) By using the Hybrid Approach, you are essentially using FreeSWITCH as your logic and media engine (to handle WebRTC and call control) and Twilio merely as the carrier (to bridge calls to the PSTN). This approach drastically reduces costs (Twilio Elastic SIP Trunking is significantly cheaper than the Twilio Client SDK) and gives you granular control over the call audio. The Architecture Blueprint 1. React Frontend: Uses (or similar) to connect to FreeSWITCH via WebRTC (WSS). 2. FreeSWITCH (Middle Layer): Acts as the PBX. It bridges the WebRTC stream (from the browser) to a standard SIP stream. 3. Twilio (Carrier Layer): Connected to FreeSWITCH via Elastic SIP Trunking. It takes the SIP stream and term...

Incoming calls reach the phones, Intermittent issues such as one-way audio where caller can hear us but we cannot be heard. The signalling path is Kamailio acting purely as the control-plane SIP proxy, then the media is anchored by a FreeSWITCH + Asterisk B2BUA cluster. Only inbound legs show the problem; outbound audio is clean. I need a seasoned VoIP troubleshooter to: • trace SIP and RTP on all hops (Kamailio, FreeSWITCH, Asterisk, edge SBC) • pinpoint why RTP from the caller side never makes it to the far end (NAT, codec negotiation, rtpengine mis-pinning, firewall, wrong c= line, etc.) • supply the minimal configuration changes or firewall rules to restore full two-way audio without disrupting live traffic Acceptance will be: 1. SIP packet ex...

I'm looking for an experienced FreeSWITCH developer to create a robust VoIP solution. Key Features: - Call Routing - SIP Trunking - Call Recording Ideal Skills: - In-depth FreeSWITCH expertise - VoIP development experience - Strong background in call routing and SIP protocols - Familiarity with call recording technologies Please share relevant experience in your application.

I want a production-ready FreeSWITCH-based Session Border Controller that registers or peers with my clients’ PBXs by username and password, transcodes to Opus, and then hands the calls off to two preset wholesale carriers. The core logic is: • Country-level routing priorities stored in MariaDB.  – Example: US/Canada → Carrier 1 first, fail over to Carrier 2; EU → Carrier 2 first, fall back to Carrier 1 on 404 or no answer. • Each client may present several PBXs and DIDs, all of which must map cleanly to those database rules. • Carrier trunk details stay hard-coded in the FreeSWITCH XML/JSON configs; only the client and route data live in MariaDB. • CDR I also need a small web interface (PHP, Python Flask or a similarly...

...looking for a Go-savvy FreeSWITCH specialist who can dive straight into a stubborn WebRTC issue that’s crippling call stability. The goal is simple: identify the root cause, patch it cleanly, and leave my stack handling WebRTC calls as smoothly as it does SIP.
