Smartvox is a Limited company established in 2004 and registered in the UK. Our main focus is the design and provision of OpenSIPS solutions for ITSP’s. We can provide solutions based on OpenSIPS and rtpengine to secure your network-edge without having to pay crazy prices for a commercial SBC.
We provide outstanding expertise in this field and have extensive experience of SIP and all versions of OpenSIPS up to v2.4. This is complemented by familiarity with Asterisk, Kamailio, MySQL, Teams, fail2ban, Docker, Pacemaker, Homer, FreeSWITCH, LetsEncrypt, iptables, etc. We have experience developing bespoke scripts, mostly using bash, and are happy working on various Linux distros. Our range of test facilities includes cloud-based SIP servers and automated utilities to generate or receive traffic.

Please note, John retired at the end of 2020 so we are unable to take on any new clients or large projects. Instead, any working time is now focussed on adding new OpenSIPS articles to this wiki.
The technical articles on this site are aimed at VoIP professionals and other users of open source VoIP products. They are organised in categories for ease of navigation. Use the Category headings shown on the right or the tabs along the top of the page to find the information of interest to you. Please also use the like button at the end of each article to show your appreciation – or leave a comment. Your feedback is most welcome.
Here’s hoping that things turn out better for everyone in 2021 than they did in 2020. With all these lockdowns, it does at least mean I’ve had more time to write new posts for this wiki.
