Network Setup

Interaction with the company infrastructure

The following protocols and connections can be used to interact with the customer IT infrastructure. Such protocols and ports must be Allowed in the customer firewall or NAT system.

Interactions between Imagicle UCX Attendant and Agent Console Clients and the UCX Suite on-prem or Cloud

Following protocols and connections are used between Imagicle UCX Console clients and UCX Suite server(s). These connections are used by following clients:

• UCX Attendant Console Professional
• UCX Attendant Console Enterprise
• UCX Agent Console Advanced 1
• UCX Agent Console Advanced 2
• UCX Agent Console Advanced 3

Interactions between Imagicle UCX Attendant and Agent Console Clients and Cloud-based Microsoft Services

Following protocols allows to support media traffic and relevant signaling in a MS-Teams environment, supporting ACS SDK Services:

Interactions with the Calling Platform

The following protocols are used to interact with the Calling Platform. Such protocols and ports must be allowed in the customer firewall or NAT system.

* Cisco devices typically work in the 16384-32766 UDP port range.

Interactions with IP Phones and other telephony devices

Following protocols are used to interact with the IP phones, ATA devices, Voice Gateways and Session Border Controllers. Such protocols and ports must be allowed in the customer firewall or NAT system.

* Cisco devices normally work in the 16384-32766 UDP port range.

Interactions among Imagicle UCX Suite cluster nodes

Following protocols are used for inter-node communications between two joined nodes in the same Imagicle High Availability cluster. If HA environment involves a Disaster Recovery scenario, below protocols and ports must be allowed among different Data Centers, over a WAN.

*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.

Other network communication

Following protocols and connections can be used to interact with the customer IT infrastructure. Such protocols and ports must be Allowed in the customer firewall or NAT system.

Communications with Internet services

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

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.

Single Sign On (SSO)

To leverage the Single Sign On authentication, the user PC should be able to reach some cloud services. Please refer at this page for the details.

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.
