  • UDP: 1719 (RAS), Dynamic range for media
• SIP:
  • TCP/UDP: 5060 (Non-TLS), 5061 (TLS)
  • UDP: Dynamic range for media
• HTTP/HTTPS:
  • TCP: 80 (HTTP), 443 (HTTPS)
• Other Ports:
  • TCP: 22 (SSH), 23 (Telnet), 69 (TFTP), 123 (NTP), 389 (LDAP)
  • UDP: 53 (DNS), 161 (SNMP), 5004-5005 (RTP/RTCP)

Ensuring these ports are open is essential for the Poly G7500 to communicate effectively with other devices and servers. Firewalls can often block these ports by default, so you'll need to configure your firewall settings to allow traffic through these ports. Regularly auditing your firewall rules will help maintain connectivity and prevent unexpected issues.

Protocol Requirements

The Poly G7500 supports several protocols. Here’s a quick rundown:

• SIP (Session Initiation Protocol): A signaling protocol used for initiating, maintaining, and terminating real-time sessions that include voice, video, and messaging applications. SIP is widely used in VoIP (Voice over Internet Protocol) systems and is essential for call control and session management.
• H.323: An older standard for video conferencing, still used in many legacy systems. H.323 defines the protocols for establishing and managing multimedia communication sessions over packet-based networks.
• RTP (Real-time Transport Protocol): A standard protocol for delivering audio and video over IP networks. RTP provides end-to-end transport functions suitable for applications transmitting real-time data, such as streaming media and video conferencing.
• RTCP (RTP Control Protocol): Works in conjunction with RTP to provide quality of service (QoS) feedback and control information. RTCP monitors the transmission statistics and provides feedback to the sender, allowing them to adjust the encoding and transmission parameters to optimize the quality of the media stream.
• HTTP/HTTPS: Used for web-based management and software updates. HTTPS provides a secure, encrypted connection for accessing the system's web interface and downloading updates, ensuring the integrity and confidentiality of the data.
