Documentation & guides.

Reference material for operators who configure, deploy, and run carrier-grade voice infrastructure. Start here if you are wiring a SIP trunk into VICIdial, evaluating codec choices, or learning the standards that govern every call on the SIPNEX network.

The guides below cover three layers: protocol references (SIP, RTP, E.164) that explain what is happening on the wire, configuration guides for common platforms (VICIdial, Asterisk, FreePBX) with tested templates, and operator-level glossaries and comparisons that help you choose the right codec, trunk sizing, or carrier configuration for your workload. Each guide is written for the person actually doing the work — dialer operators, call center admins, and the engineers who sit between a PBX and the PSTN. If something is missing or unclear, email contact@sipnex.ca and we will either answer it directly or add it to the library. For configuration help that goes beyond the written material, our engineering team is available during business hours — you are not going to get a tier-1 helpdesk, you are going to get the person who can actually open the config.
