Star topology VoIP network with dual-VLAN architecture separating voice (VLAN 44) and data (VLAN 1) traffic across a core switch and four access switches. VOIP Router connects to ITLTSW00 core switch, which distributes tagged trunk links carrying both VLANs to access switches ITLTSW01–ITLTSW04, each serving multiple IP phones on dedicated VLAN 44 access ports. This design isolates voice traffic for QoS prioritization and security while maintaining data connectivity on VLAN 1, reducing congestion and improving call reliability. Fork and customize this diagram on Diagrams.so to document your own multi-switch VoIP infrastructure, adjust port allocations, or add additional access layers. Reserved ports on ITLTSW01 (port 21) and ITLTSW03 (ports 11–13) are marked for future expansion or maintenance.
