Information Technology Resources

Here are some of our favorite and most helpful resources with information relating to what we do:

VoIP Info Wiki - A user community for VoIP information, with tutorials, help documents, manuals etc relating to things from VoIP software, to Service Providers. The user community behind VoIP and especially the open source projects such as Asterisk and SER are extremely helpful, and one of the best reasons to utilize them for your business.

The Asterisk Guru - A very helpful site with a good direction. A solid collection of tutorials for installing and configuring asterisk.

Digium - The official website for the company founded by Mark Spencer (the creator of Asterisk Open Source PBX). This is the place to purchase an official enterprise license, the absolute best technical support, and asterisk certified compatible hardware.

The Asterisk Homepage - The official website for the software development including forums, developer blogs, and manuals.

ConnectU Scripts

We at ConnectU believe in sharing information and promoting open-source software.
That is why we are sharing some of our custom scripts with the Asterisk community. If you have any questions about the below scripts, feel free to contact us.

Flip1405

Flip1405 consists of two scripts: Primary and Secondary. Each script is placed on the Primary and Secondary Asterisk servers and set to run every minute via cron. In the event of an Asterisk process crash, the script polls upd 5060 on the primary server, determines Asterisk is not running, and starts the process. If the process does not start, the virtual IP is released and the secondary Asterisk server takes over. Whenever the virtual IP is changed from server to server, the ARP tables must be updated because each servers NIC has a different MAC address. The script has a built in gratuitous ARP request that is broadcasted 5 times. This will update the ARP tables on any managed switches that are connected to the server(s). This means that within 5 seconds of taking over the virtual ip, the machine is pingable.
