We Love Open Source

Open source software is software that can be freely used, changed, and shared (in modified or unmodified form) by anyone. (see the Open Source Initiative)

The Palner Group, Inc. proudly supports and contributes to Open Source Software. Our go-to tools for VoIP communication include:

Kamailio SIP Server

Kamailio (formerly OpenSER) is an Open Source SIP Server released under GPL, able to handle thousands of call setups per second


Asterisk powers IP PBX systems, VoIP gateways, conference servers and other custom solutions. It is used by small businesses, large businesses, call centers, carriers and government agencies, worldwide.


FreeSWITCH is a scalable open source cross-platform telephony platform designed to route and interconnect popular communication protocols using audio, video, text or any other form of media.


Although we mostly deploy on either Debian or CentOS, we do consider other flavors of Linux that may be preferred by the client.
