System Requirements

This article lists everything needed to deploy and connect VoIP Detective: the supported virtual environments, the resources the virtual machine needs, and the network ports required to receive call data from each supported platform.

Supported Platforms

VoIP Detective is a virtual appliance. It runs on any one of the following virtual environments:

Virtual Environment	Minimum Version
VMware ESXi	5.5+
VMware Workstation	15+
VMware Player	Supported
Microsoft Hyper-V	Hyper-V 10+ / Windows Server 2016+
Proxmox	Supported
Nutanix	Supported
Linux KVM	Supported

Phone system: Cisco Unified Communications Manager 8 or later. (Webex Calling, Microsoft Teams, and Cisco CUBE are also supported as call data sources – see Connectivity below.)

Virtual Machine Requirements

Resource	Requirement
vCPU	2
Memory	16 GB
Storage	1 TB (may be thin provisioned)
Internet access	Outbound access to *.voipdetective.com (see Connectivity). PRO users may bypass this with an offline license.

ℹ️ Tip: Storage is the resource most affected by call volume and retention. Thin provisioning lets you start small and grow as your call database fills up.

Connectivity

Open the following ports so VoIP Detective can receive call data. Each platform is independent – you only need the ports for the platforms you use.

Cisco Call Manager (CUCM)

Port	Direction	Purpose
22	CUCM → VoIP Detective	VoIP Detective has a built-in SFTP server. Once you add it as a “billing server” in CUCM, CUCM pushes CDR/CMR files to it over port 22 (SFTP).
8443	VoIP Detective → CUCM	Optional. Read-only AXL access used to import end-user names and device data.

Cisco CUBE

Configure CUBE (Cisco Unified Border Element) to send its CDRs to VoIP Detective over FTP or SFTP (port 22 for SFTP).

Microsoft Teams

Teams reporting requires outbound access (port 443) from VoIP Detective to retrieve call records:

Purpose	Endpoint
Call data (Microsoft Graph)	https://graph.microsoft.com
OAuth / authentication	https://login.microsoftonline.com/

Webex Calling

Webex Calling reporting requires outbound access (port 443) from VoIP Detective to your Webex region. The endpoint depends on your location:

Region	Endpoint
Token exchange (all regions)	oauth.voipdetective.com
United States	analytics-calling.webexapis.com
European Union	analytics-calling-eu.webexapis.com
Asia Pacific	analytics-calling-in.webexapis.com
Government	analytics-calling-gov.webexapis.com

Outbound – Product Services

VoIP Detective Free contacts the following over port 443. PRO users can remove this requirement with an offline license.

Destination	Purpose	Port
www.voipdetective.com	Tests whether internet access is working and notifies the administrator when an update is available.	443
update.voipdetective.com	Provides upgrade details and delivers upgrades, applied from the GUI.	443
license.voipdetective.com	Contacted about every 7 days to verify the license is still active.	443

Outbound – Optional Services

SMTP server – to send scheduled reports and alerts by email.
Microsoft 365 OAuth2 - for users of Microsoft 365 email.
Linux OS updates – if you update the underlying Alma Linux OS from the command line, the yum package manager needs access to standard Linux repositories over ports 80 and 443.

Important: VoIP Detective is not designed to be internet-facing. Ensure it is not reachable directly from the internet and is not placed in your organization’s DMZ.
