Main principle - as powerful as possible.
For 1 server solution:
| Component | Minimum requirement | Recommended |  We provide as Hosted Solution |
Comment |
| CPU | Quad Xeon/Intel Core i5+ | any higher CPU | Intel(R) Xeon(R) CPU E3-1245 V2 @ 3.40GHz |
|
| RAM | 4 Gb | 16 GB or more | 32 GB |
|
| HDD | 50 Gb | 100 Gb or more, SDD (Solid State Drives), RAID Type 1 | 2 x 120 GB SSD RAID 1 |
all space must be assigned to / partition |
| OS | Centos 6 | x86_64 | Centos 6.2 |
|
| Brand | Any | Intel, DELL, HP, Fujitsu | Intel |
Such server should handle up to 500 calls while calls are not reencoded (also known as transcoding) and GUI is not in use.
We also recommend to have clean server without any additional packets installed.
For many servers solution:
Asterisk server: same requirements as above, except SSD would not increase performance so it is not needed and 4 GB of RAM is sufficient. CPU is most important component here. If Proxy solution is in use, Asterisks cannot be under NAT, it must have Public IP for SIP and RTP traffic.
Database server: same requirements as above and SSD is highly recommended here. There should be 100GB or more space as database grows fast on high traffic. Fast data storage device and CPU are most important here. If more than one Database server is in use, UPS (Uninterruptible Power Supply) devices must be used for these servers, otherwise power outage would cause broken replication.
GUI server: same requirements as above, except SSD would not increase performance a lot. HDD with more space is recommended here.
Proxy server: same requirements as above, except 4 GB of RAM and 40 GB on HDD will be enough here. SSD would not increase performance. Proxy server cannot be under NAT, it must have Public IP for SIP traffic.
Redundant servers: there are no special requirements on server hardware if server is part of redundant system. However, there are requirements for network to which servers are connected:
- Both servers should be within same subnet.
- Both servers should be able to broadcast packets to UDP 694 port.
- Both servers should be able to receive packets broadcasted by other server.
- There should be Virtual IP reserved in Subnet.
- Both servers should be able to work with that Virtual IP (only one server at same time).
If any of requirements above are not met, in some cases it is possible to adapt different network configurations or services (like "IP Failover"). However, management/configuration/development of third party software (like special scripts) needed to adapt special solution should be performed by servers owner.
