My Set Up consist of two Asterisk servers, Cisco CME, IP phones, Session Border Controller, and a Digium IAX ATA A100I. Asterisk server B is a Dell Dimension XPS T500 PC with a P3 500 MHz processor, 512mb of RAM, 14GB of HD space, running FreeBSD 5.3, and Asterisk version 1.0.3. Asterisk Server A is a Crystal Ria with dual P3 850mhx processors, 512mb of RAM, 20GB of HD space, running Redhat Fedora Core 1, and Astrisk CVS head 7/14/04. The Cisco CME is a Cisco 3662 which you can obtain further configuration and version detail by selecting the Cisco tab above.
Currently both asterisk server set ups do not support any PSTN connection. All calls are routed via SIP trunking through a SIP network provider or IAX between PBXs. However, I will be adding to server B a Digium TDM22B (2 FXO/2FXS), TE110P (single T1 CTI), and S00I "IAXy" ATA in the near future. Once I receive these items, and install, I will update the web site with installation and configuration procedures.
