AIS Managed VoIP

As communication methods become more fragmented, office phone use continues to decline but office phone system and service prices have increased in many cases. In designing a robust, reliable, VoIP platform, AIS selected the Asterisk VoIP server software, which is perhaps the most mature and widely deployed VoIP server. Hosting in Amazon Web Services with Geo-Redundant availability zones and connect to the public phone network using geo redundant sip trunks provided by Twilio allows for carrier grade reliability.
