Inter process communications

*SQL Server listens to inbound communications using a random TCP port. To force a specific port (TCP 1433), please follow the procedure available here: https://docs.microsoft.com/en-us/sql/database-engine/configure-windows/configure-a-server-to-listen-on-a-specific-tcp-port

Note: Maximum allowed latency (RTT) for inter-nodal communications is 100msec.

In the case of High Availability configurations that involve multiple UC Suite nodes, full connectivity must be available between UC Suite servers (no firewall or NAT) to allow content synchronizations between multiple nodes.

Communications with Internet services

There are a number of external Internet-based services that should reachable from IAS Server. These include Imagicle Online Cloud Licensing Server and Internet email services, like Office365 and Google Mail.

Imagicle Online Cloud Licensing Server and Internet email services

Starting from Imagicle UC Suite rel. 2019.Summer.1, Imagicle UC Suite allows to configure a proxy server to reach above Internet services. More info are available in this KB.

Traffic requirements

In addition to the network connections described above and related firewall rules, following considerations and requirements must be considered in a deployment scenario.

  • SIP / H.323 / T.38:
    Voice and fax streams with real time requirements:
    • Low Latency (maximum 80 ms RTT)
    • Wide Bandwidth (up to 80 Kbps for each simultaneous call, depending on the adopted voice codec)
  • TAPI / JTAPI
    Call Control with real time requirements:
    • Low Latency (maximum 80 ms RTT)
    • Lightweight protocol (no need for wide bandwith)
  • (S)FTP
    • Basically file transfer with no real-time requirements
    • Used bandwidth depends on the actual traffic figure
  • AXL
    • Medium Latency (up to 150 ms RTT)
    • Low Bandwidth
  • ECC CURRI (HTTP)
    • Low Latency (maximum 80 ms RTT)

Additional Server requirements

The Internet Options of the Imagicle Application Suite server should have the proxy settings disabled. Configuring a proxy may impact on service-to-service communications with the PBX or with other UC Suite nodes.
