The PC hardware requirements are determined by the size and complexity of the devices that you want to attach to the system.

Small deployments

For smaller deployments of under 30-channels PRI/SIP, 8-Channels BRI or 8-channels of POTS/Analogue, a relatively low-specification PC can be used:

• Windows 7/8/8.1/10, Windows Server 2008 R2, Windows Server 2012, Windows Server 2016
• Dedicated USB hub and controller (Only with Echo USB, Echo cards will have a RJ45 connection on the back so not required.)
• 4GB RAM
• Intel Core i5-2.4 Ghz or equivalent -
• PC should not be used for other heavy-CPU tasks

Medium-sized deployments

For single-site deployments up to 240 ISDN channels, the following PC specification is recommended:

• Windows 7/8/8.1/10, Windows Server 2008 R2, Windows Server 2012 or Windows Server 2016
• PCI/PCI-Express slots for Echo hardware
• 8GB RAM
• Intel Dual-Core i5 3Ghz or equivalent
• Keyboard, and mouse (not necessary for Windows 8)
• PC must be a dedicated machine

Large deployments/arrays

Installations of above 300 ISDN channels / 100+ SIP channels would require the following specification at each site:

• Windows 7/8/8.1/10, Windows Server 2008 R2, Windows Server 2012 or Windows Server 2016
• Intel Xeon ® (10-core+) 2.8 GHz
• 16 GB RAM
• Sufficient PCI/PCI-Express slots for ISDN/Analogue hardware
