Deployment

From the planning phase, the following data and information should have been collected:

• Number of additional IP addresses needed
• Link bandwidth on MAN/WAN connections
• Number of TDM trunk lines needed

QoS: It is assumed that all network devices support QoS mechanisms and that QoS is possible to enable in the routers and switches. It is of great importance that VoIP traffic is given priority to other traffic, and that voice packets are discarded in a controlled fashion.

VLAN: VLAN allows LAN traffic to group or segregate. It also allows prioritizing different data classes by switches. Do the switches support VLANs and IEEE 802.1p/q?

Shared Hubs / Repeater: Shared Hubs do not offer QoS. Verify that device attached to a repeater/hub not is intended to use for VoIP services.
