You will get You'll get custom Asterisk application with DB connection, & API calls
Project details
Most Asterisk developers can write dialplans, but I go way beyond that. With 10+ years of experience in VoIP, PBX, and real-time communications, I build custom Asterisk applications that are not only functional but also scalable, secure, and business-ready.
What makes my work stand out:
Deep Telephony Expertise – ARI, AMI, AGI, SIP, RTP.
End-to-End Vision – I understand how Asterisk fits into the bigger system (CRM, APIs, cloud, mobile apps).
System-Level Debugging – I troubleshoot at both the code level and network protocol level, ensuring reliability.
Custom Solutions – From IVRs to AI-powered voicebots to advanced call routing, I tailor every project to your exact needs.
Proven Track Record – Delivered enterprise-grade telephony solutions used by banks, enterprises, and startups.
You don’t just get an Asterisk script, you get a well-architected solution that works seamlessly within your whole system.

About Vishal
Sofware Engineer | Asterisk, AI Voicebot, Kamailio, FreePBX, VoIP
Lalitpur, Nepal - 3:17 am local time
What sets me apart is not just deep expertise in telephony and VoIP systems, but also the ability to bring together backend, mobile, and web technologies into a seamless, reliable solution. I understand how all parts of a system connect, whether it’s debugging network-level SIP/RTP flows, optimizing server performance, or refining user experience on mobile apps.
I believe in building products that are technically robust, visually distinctive, and business-driven. My approach is simple: work with integrity, deliver beyond expectations, and aim for long-term partnerships rather than one-off projects.
