Applications
- Software based PBX systems
- Channel banks and TDMoverIP
- ISDN crypto gateways
- VoIP gateway to the public telephone network or VoIP Gateway for internal extensions
- Least Cost Router for VoIP or CbC
Scalability
- Sirrix.PCM-Bus supports up to 8 ISDN-cards per system with automatic system-wide clock synchronisation
- By interlinking multiple systems, a virtually arbitrary amount of extensions can be served.
- The connection to the public net can be achieved by an arbitrary number of BRI- or PRI-ports.
System Requirements
- Arbitrary computer system
- Free 32 Bit PCI 2.1 slot
- Linux with kernel 2.6
