Moreover, Layer 2 switches deliver the ability to increase bandwidth to the wiring closet without adding unnecessary complexity to the network. At Layer 2, no modification is required to the frame content when going between Layer 1 interfaces, such as Fast Ethernet to 10 Gigabit Ethernet. In review, the network design properties of current-generation Layer 2 switches include the following:
Session management, call traffic capacity, bandwidth control, and Quality of Service QoS Scalability and high availability SIP trunk monitoring Another key area of consideration includes interworking and interoperability, which is discussed further in Chapter 8, "Interworking.
Not all countries regard Voice over IP VoIP calls in the same way, and although virtually no country regulates what can be deployed inside an enterprise network, several countries regulate to varying degrees what calls can be handed off between an enterprise and a public service provider network.
Ensure that you become familiar with country-specific regulations when deploying SIP trunking, especially if the endpoint the site where the call originates and the SIP trunk where the call enters a public network are in different regulatory jurisdictions.
A second consideration is sheer distance, with the hairpinned media paths resulting from the centralized SIP trunk model discussed in the Chapter 6. If the remote office originating the call is in California and the central SIP trunk is in New York whereas the PSTN destination of the call is again in California, the media path for this call traverses the North American continent twice, adding latency to the end-to-end call.
Adding latency to signaling paths is much less of a concern it might add marginally to post-dial delay but does not impact voice quality on the active callbut latency of the media path directly affects voice quality and should be taken into consideration when designing and connecting a SIP trunk into an enterprise network.A business plan is a roadmap for your small torosgazete.com is both process and product.
