Specifications

Main principle - as powerful as possible. For single server solution we recommend:

RAM 8 Gb 32 GB 32/64 GB
HDD 100 Gb SSD (Solid State Drives) all space must be assigned to / partition; ext3 file system; 500+ GB for M2 systems 500+ Gb, SSD (Solid State Drives)/m2 nvme, RAID Type 1 all space must be assigned to / partition; ext3 file system 2 x 240/512 GB SSD RAID 1
OS Centos 7 x86_64 Centos 7 x86_64 OS timezone must be set to UTC or at least to Timezone which does not have daylight saving
NIC Any M2: Intel I210, I350 M2: Intel I210 Realtek RTL8111/8168/8411, Intel 82574L are weak NICs, not recommended
Brand Any Intel, DELL, HP, Fujitsu Intel


It is required to have clean server without any additional packets installed.

Default Centos kernel is required for all functionality to work correctly.



Requirements for multi-server deployment

Asterisk or Freeswitch 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. Must be located as close as possible to Database server to avoid problems caused by latency.

Database server: same requirements as above and SSD is highly recommended here. SSD is must if system has more than one Asterisk server. There should be 100GB or more space as database grows fast on high traffic. It is recommended to start with at least 400GB on M2 systems. 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. 8Gb RAM minimum. Must be located as close as possible to Asterisk server to avoid problems caused by latency.

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.



Virtualization

MOR system was tested and working (with low call capacity) on following Virtualization technologies:

  • VMware
  • VirtualBox
  • XEN

In general we do not recommend to use Virtual machines for multi-server solutions, especially when those Virtual machines are running on same host. Best multi-server system performance is achieved when running on Dedicated servers. If multi-server system is chosen to get better calls capacity, then Dedicated servers must be used too.

Only GUI server on VM is acceptable.



FAQ

  • Do you have the provision of STUN and TURN servers on your end?

No, we do not provide STUN servers. MOR should receive Public IPs on SIP headers. NAT traversal should be done on customer's side.
