About this Gig

Are you looking to bridge your traditional phone lines (PSTN/GSM) with a modern IP-PBX? I will help you design, configure, and troubleshoot your Asterisk-based VoIP system and integrate seamless hardware gateways for crystal-clear communication.

Asterisk Expertise: Installation and custom dialplan configuration (extensions.conf, pjsip.conf).
Gateway Integration: Configuration of FXS/FXO, GSM, and E1/T1/PRI gateways (Dinstar, GoIP, Sangoma, Grandstream, Yealink).
SIP Trunking: Connecting your local PBX to international providers for cost-effective calling.
Protocol Mastery: SIP, PJSIP, IAX2, and RTP optimization to fix "one-way audio" or "jitter" issues.

3. Core Service Offerings

PBX Setup: Full installation of Asterisk, FreePBX, or Issabel on Linux (Ubuntu/CentOS).
Hardware Bridge: Mapping GSM SIM cards or Analog lines to SIP extensions.
Security & Firewalls: Implementing Fail2Ban and custom iptables to prevent SIP brute-force attacks.
Call Features: Interactive Voice Response (IVR), Call Queues, Recording, and CDR (Call Detail Records) reporting.
