Five9 LabA student's open lab: learning and sharing, free for everyone.

SIP and carriers

Name the path. G.711 is the default you can cite. Studio ports are not every trunk.

Three ways a call can enter

The technical requirements describe three SIP stories. Five9 can provide ITSP trunks. Your ITSP can connect to Five9 session border controllers, and there is a checklist for that.

DNS, codecs, and the default voice

The requirements prefer DNS SRV for the SIP targets. G.711 is the default codec, and the PDF describes it as uncompressed. Do not invent a packetization time. A 20 millisecond ptim

How much bandwidth a seat costs

The requirements give planning numbers. Agent Desktop Plus and the Plus adapters are 128 kbps. The Java agent is 88 kbps. Agent Assist adds about 12 kbps. A VPN adds about 64. CRM

NAT, idle timers, and split tunnels

NAT and PAT are acceptable. Double NAT is not. UDP bindings that idle out cause one-way audio. The requirements use a 30 second UDP idle timeout as the planning number, and they te

Direct Connect and the edges

Direct Connect in the requirements is a Layer-3 handoff. There is no Layer-2 requirement. The port is 10, 100, or 1000 full duplex, and failover uses BGP. Equinix Fabric edges name

TLS, and ports that are not universal

Unencrypted APIs are not the story. TLS 1.2 is required. TLS 1.1 is not supported. The requirements also list TLS 1.3 inbound ciphers: AES-128-GCM, AES-256-GCM, and CHACHA20.

Headsets, and the call that only fails one way

USB noise-canceling headsets are the recommendation. Analog headsets are not supported. Wireless is not recommended once you are above roughly ten agents. Windows 11 Efficiency Mod
