SIP (Session Initiation Protocol) is an important industry standard protocol that is widely used for establishing, modifying and terminating multimedia sessions or voice and video calls across IP networks. It allows for a high degree of flexibility regarding codecs, and media types that can be interchanged during the session. A SIP Engineer is a skilled software developer/programmer that specializes in network collaboration protocols like SIP, RTSP and RTP that help enable peer-to-peer communication over the internet, reducing costs and allowing for more efficient deployment of voice and video conferencing.

A SIP engineer can do many things ranging from building Voice over IP systems to creating specialized multimedia applications. They will build sophisticated systems with various components such as audio encoders/decoders, media gateways, signaling gateways and user agent clients. They are also responsible for configuring and optimizing the system to achieve the best results and creating real-time simulations like teleconferencing or IVRs (interactive voice response).

Here’s some projects that our expert SIP Engineer made real:

  • Secure upgrades for open source communications protocols
  • Debugging and solving complex VoIP issues
  • Carrier grade server implementations in cloud environments
  • System wide port configuration optimization
  • Integrating complex third party applications with existing softwares
  • Coordinating German DIDs/Voip Numbers with PBXs
  • Developing automated communications using Python

SIP Engineers are always in demand as great knowledge in this protocol is essential for setting up reliable communication services with low latency at an affordable rate. At Freelancer.com you can hire an experienced SIP Engineer who not only understands the inner workings of current standards but also able to keep up with new developments in the communication world. Post your project today and get the expertise you need to create a powerful yet cost effective communications environment!

    Configure Dinstar Gateway Magnus
    6 dias left
    Verificado

    I have a Dinstar 8-port GSM/VoIP gateway here in the UAE and I’m ready to put it into production. My preferred stack is MagnusBilling, so the first task is a clean installation and full configuration of Magnus on a fresh Linux VPS. Once Magnus is up, I need the gateway registered, trunks and routing rules created, and a quick test call flow that proves inbound and outbound calling works end-to-end. Security is a must-have from day one. I want a properly hardened VPS firewall and strict IP whitelisting so only approved addresses can reach SIP, SSH and the Magnus web interface. If you have additional best-practice suggestions, I’m open to them, but IP whitelisting is non-negotiable. Deliverables • MagnusBilling installed, updated and secured on my VPS • Dinstar DG...

    I have a Cisco UC540 on-site and a live SIP trunk supplied directly by our ISP. All the registration details—SIP username, password, registrar, codecs, DID ranges—are already in hand; what I need is a specialist who can jump in remotely, register that trunk on the UC540 and make sure both inbound and outbound calls flow cleanly. Here is how I picture the engagement: • Remote configuration through CCA or pure CLI, whichever you are most efficient with. • Correct dial-peers, voice class codecs and translation rules so our full DID block reaches the right ephone-DNs and outbound calls present the main number. • Basic feature verification: two-way audio, multiple simultaneous calls, caller-ID, and voicemail routing to CUE. • A brief hand-over showing the...

    I want to sharpen my day-to-day troubleshooting skills around Twilio Programmable Voice and, in particular, dive deep into TwiML and call-flow logic. The goal is to meet regularly—live, one-on-one—to dissect real customer-reported issues, replay them with sanitized data, and step through practical fixes. Topics that matter most to me include: building and debugging TwiML, shaping call flows, handling webhooks, analysing Voice Insights, and interpreting SIP-level problems such as latency, jitter, and packet loss. I already work in technical support, so the sessions should feel like an advanced lab where we pull log files, test APIs, and reason through what is really happening on a call. This is ongoing mentorship rather than a packaged course. We can agree on a cadence a...

    I work in technical support and want to sharpen my real-world troubleshooting skills around Twilio Voice. I’m looking for an experienced engineer who can meet with me one-on-one on a recurring basis (video or screen-share) and walk through practical scenarios rather than a pre-packaged course. Primary focus areas • Twilio Programmable Voice & TwiML • Voice APIs, SDKs, Webhooks • SIP trunking and Voice Insights During our sessions I’d like to: • Recreate and dissect customer-reported issues, latency, jitter and packet-loss cases, call-flow misconfigurations, webhook failures and SIP registration problems. • Step through live debugging with tools such as the Twilio Console, CLI, ngrok tunnels, Wireshark traces and call log analytics. &...

    We are looking for a Senior Solution Architect with strong experience in VoIP, WebRTC, SIP, telecom infrastructure, AWS, and Saudi Arabia technology/telecom requirements. This is initially an architecture and technical documentation project, NOT a full development project. We have a client who wants to build a large-scale calling platform in Saudi Arabia. We already have an initial technical concept, but we need an experienced architect to review it, validate the approach, identify technical and regulatory risks, and prepare a professional architecture document that we can present to the client. If the client approves the architecture, there may be a separate opportunity to continue with the full implementation. Project Background The proposed platform will allow survey agents to make...

    I already have the ATA hardware on hand; I just need it hooked up and quickly configured so my analogue desk phone can live on a digital (VoIP) line. The goal is simple: once we’re done, I want to lift the handset and place or receive a basic call with clean audio. You’ll handle the cabling from the phone to the FXS port, link the adapter to my router, enter any SIP details my provider requires, and verify dial tone and call quality. No voicemail or caller-ID tweaks are needed right now—just rock-solid basic calling. Please be comfortable with common ATA menus, impedance settings, codecs, and NAT traversal. You can walk me through it over a video session or, if you’re nearby, come onsite. Deliverables • ATA wired, powered, and showing normal status light...
