Design a network for voip over wan

[rajendra535]

Hi all,

            I need your valuable suggestions how to design a network of voip using voip.

Suppose there is a Site A and Site B and you are using different service providers and creating different vlans in each site for voice and data.Lets say it like vlan50 for voice and vlan 51 for data and in the other site vlan 100 for voice and vlan101 for data.How do you give the priority for voice packets while sending in the network and basically please explain the needed hardware that you use for this design (like what are the equipments ,media server gateway,dhcp server,ethernet switch , voip phones etc..).

                                         All genius people out there ,kindly help me with this problem.

Hi Rajendra,

Very open query but I will see how much I can give inputs.

Since you have only two site. you can go for CME instead of full CUCM. If you have slightly more sites you can go for CUCUMBE. Or if you have more number of sites you can go for CUCM.

Giving priority to voice packets is given by QOS and the configuration example is given in QOS SRND.

Other details will be given in CUCM SRND.

You can use sizing tool to see what elase is required.
