Up-front rightsizing and capacity planning are critical aspects of VoIP, as many organizations have learned the hard way -- after VoIP deployment. "Rightsizing" refers to the provisioning of appropriately sized WAN links to support convergence of voice traffic onto the data network.
In most cases, the current WAN link will need to be upgraded in order to support converged voice traffic. The question that must be answered is how much bandwidth is required for each WAN circuit, and this question cannot readily be answered without significant analysis of the current voice call patterns and volumes, as well as future call patterns and volumes using VoIP.
