Hardware Specification Guidelines
Stick to reputable name brand hardware.
KVM access is required for FlySIP Support to access your installation for installation & upgrades.
** A note about Real CPU cores, versus Hyper-Threads or Virtual Cores
Our documentation states “physical cores”. This excludes virtual or hyperthreading cores.
For example, the Intel E5-2690 processor is marketed as having 8 physical cores and 8 virtual cores or “Threads”. This CPU counts as having 8 physical cores.

Media Relay hardware guidelines
Media Relay Cluster is a beta product, and only available to enterprise customers participating in our beta program. If you wish to take part in this program, please contact sales@flysip.com
The relay or proxying of media through an intermediary system is useful for some specific scenarios, such as NAT helping and network topology masking. Relaying media will increase the network requirements, bandwidth resources and CPU resources of your system.
Media Relay causes the RTP stream between your client system and your vendor to travel via your FlySIP Softswitch infrastructure.
The type of codec used by your client & vendor has a large bearing on the resources consumed. For example, here is the example of relative sizes between a selection of popular codecs:
Codec / Bandwidth usage examples
| G.711 | G.729/G.723 | |
| 2,000CC / 30CPS | 250 MBit/sec | 40 MBit/sec |
| 3,000CC / 50CPS | 375 MBit/sec | 60 MBit/sec |
| 6,000CC / 100CPS | 750 MBit/sec | 120 MBit/sec |
| 10,000 CC / 150 CPS | 1.25 GBit/sec | 300MBit/sec |
The point to remember here is that all media traffic, even using the same codec is not always equal in terms of the resources required to relay it.
Medium spec Media Relay hardware suitable up to 2,000 Concurrent Calls, 30 CPS
| CPU | 16 Core, 2.5GHz, Intel Xeon E5 or better or comparable AMD** |
| RAM | 8GB |
| Disk | Mirrored SATA hard drives or better |
| Network Interface | GigE Network Interface Intel(R) PRO/1000 PCI Express Gigabit Ethernet. Bonded (FEC) interface is recommended |
Media Relay hardware server/capacity table
| Cluster Size (Number of servers) | |
