andrewgroup Posted January 10, 2008 Report Share Posted January 10, 2008 Using our configuration of a Windows XP Pro System with 45 Extensions and a regular call count of 15+ calls peaking at 23 (Full PRI) we base the following tips. A clean XP Pro or Server installation. 1GB RAM (ECC as a standard) 1 - Internal NIC for internal Phones 1 - Public Facing NIC for ITSP phones 1 - Nic for GATEWAY services (PRI or ANALOG) Set all services to manual and start to determine the minimal running services. we do use an Anti-Virus tool (but only with scheduled scans late in the day/morning. We do not use real-time scanning or real time updates as these services can consume CPU and affect active calls. We do apply the QOS recommended windows Patch. We do install Wireshark directly on the server and validate COS/TOS bits. We do use Wireshark to validate latency, SIP invites and SDP packets. We do use capable switches support both Port and VLAN tagging 802.1PQ We do use hardware based RAID Disk Controller with alerting. We do use SNMP and pull stats. We do use WMI performance monitoring. the above system when fully loaded with 23 active calls, the CPU peaks at 8% utilization and we can run Wireshark and create a complete trace and not affect call quality. your Mileage may vary.
