PBX Configuration Specialist Needed

@techs4funs

I bring more than 15 years of hands-on experience designing, implementing, developing, and maintaining Asterisk-based VoIP and PBX solutions, including complex multi-site and geographically distributed environments. One relevant project involved deploying 3 Asterisk PBXs on HP servers across geographically distant locations, interconnected to provide reliable communications for approximately 700 extensions. I was responsible for the architecture, configuration, SIP connectivity, dial plans, routing, troubleshooting, and ongoing maintenance. I have also implemented and maintained 12 virtualized Asterisk PBXs supporting decentralized offices and remote sites. These solutions included integration with multiple telecommunications technologies such as E1 gateways, FXO interfaces, and SIP trunks. My experience covers the complete Asterisk ecosystem, from system architecture and SIP trunk integration to dial-plan development, call routing, troubleshooting, performance optimization, high availability considerations, and production support. I am comfortable working with existing environments as well as designing new solutions from scratch, and I focus on building stable, scalable, and maintainable VoIP infrastructures. I would be glad to discuss your current Asterisk environment and how my experience can contribute to the project.

If you need someone who has actually built **Asterisk + SIP routing into a production voice platform**, rather than someone who only edits dialplans — this is my area. Search **“APEX Connect by AIM Systems”** on Google to see the platform I’ve been building. I’m also ready to **show you the actual implementation and walk you through the telephony architecture**. For your project, I can handle: • Geographic / prefix-based call routing • DID & number normalization • SIP trunk/provider selection • Priority & failover routing • Business-hours routing • SIP signaling & error handling • RTP/media troubleshooting • Asterisk dialplan configuration • Linux/network-level VoIP troubleshooting My telephony work includes **Asterisk AudioSocket, SIP trunks, DID pools, Twilio/Telnyx integrations, real-time call orchestration, and AI voice pipelines**. I focus on the complete call path — **SIP signaling → routing logic → trunk → RTP/media → failure handling** — so the configuration remains reliable when deployed beyond a basic test setup. Send me your current Asterisk setup, geographic routing rules, and SIP trunks. I can review the flow, propose the routing structure, implement it, and test it end-to-end. **Want to verify the experience first? I’m ready to show you the work.** Regards, Ankit

I have 10+ years of experience in IP-PBX/VoIP, working hands-on with Asterisk, Yeastar, Mitel, Alcatel, SBCs, and MS Teams voice integration — a strong match for your Asterisk call routing needs. Relevant experience: I implemented multi-site call routing for a multinational client with offices across the Gulf region, including geographic/location-based routing, DID mapping by office, SBC-based SIP trunking, and failover between sites — very similar to what you're looking for.

@An071

Hi, I have experience with Asterisk PBX, VoIP, SIP and call routing. I can help configure your Asterisk PBX for geographic/location-based call routing and troubleshoot any existing routing issues. I have experience with Asterisk dial plans, SIP trunks, inbound/outbound routing, VoIP systems and Linux server configuration. I can review your current setup and implement the required call-routing configuration according to your requirements. I’m available to discuss the details and start as soon as possib

@rizwanalam91

Hi, I can help with your Asterisk PBX call routing setup. I'm a telecom systems engineer with 13+ years building production voice/IMS platforms, currently a Senior Research Engineer at C-DOT (India's Centre for Development of Telematics), where I've designed SIP/Diameter/SS7 call routing, emergency-services call routing architecture, and deployed IMS/VoIP systems handling 1M+ subscribers and 1000+ calls/sec. I've worked hands-on with Asterisk, SIP trunking, dialplan/geographic call routing, and Linux-based VoIP network configs. For your project I'd: review your current Asterisk config, implement the geographic call routing logic you need, test failover/edge cases, and hand over documented dialplans. Happy to share examples of similar SIP/call-routing work from my telecom background. Available to start immediately and can deliver within the timeline. Let's discuss your specific routing requirements.

Hi, I can help you with this. I have more than 10 years of experience with telecommunications and VoIP environments, including Asterisk, SIP, PJSIP, Linux, call routing, dialplans and troubleshooting. I’ve worked with production call-center systems where routing reliability, SIP signaling and correct handling of call flows are critical. For your PBX I can review the existing configuration and implement the geographic routing rules, including: • Prefix / destination-based routing • Dialplan configuration • SIP trunk routing • Number normalization • Routing priority and failover • SIP troubleshooting • Call-flow validation and testing I can start immediately. If you provide the current Asterisk configuration, trunks and expected geographic routing rules, I can quickly identify the required changes. Best regards, Rodrigo Naguel
