Asterisk PBX Development, Deployment and Provisioning in Cambodia

Asterisk PBX is the #1 open source communications toolkit.

Asterisk PBX powers IP PBX systems, VoIP gateways, conference servers, and is used by SMBs, enterprises, call centers, carriers and governments worldwide.

For a small office requiring less than 25 concurrent calls it can be installed on to a $100 computer, for bigger installations supporting 1000’s of users it can be built into a high availability cluster of Asterisk PBX servers.

GreyChain Cambodia has years of experience implementing Asterisk based systems on various hardware platforms and provides a managed Asterisk installation if required. GreyChain can also implement Asterisk as a cloud based platform either hosted within Cambodia or external to Cambodia.

Asterisk PBX being an open source product is available for free, your only costs being installation and any support. Once installed on a commercial grade server you could expect years of trouble free service.

Asterisk PBX can be customised to provide voice prompts in many languages.
