VoIP in a LAN

Hello,

I have a study case to do and I have few questions.

The LAN on the one I must integrate the VoIP with AVVID CISCO is on an area of 10Km square (5miles square). Ethernet gigabit for the backbone fiber.

I read that only VLAN with a maxium of IP Phone by VLAN for dedicated Bandwidth is needed to ensure the Bandwidth. Does VLAN give enough Quality of service within a LAN or do I have to implement something else ? If

yes, what ?

Many Thanks for your help

Martial

Re: VoIP in a LAN

VLAN is used not only to ensure bandwidth; it is also brings QoS – virtually separates Data and Voice streams/LANs.

VLAN will give you enough QoS to deploy IP Telephony.

In addition I would suggest you to bring your attention to LAN design – that’s where you need to put some logic – LAN topology design and deployment of switches that supports QoS.

And last one: it is design and topology specific - sometimes it is better to separate Voice and Data in the LAN.

There are no wright and wrong choices and solutions - it is based on what works best for customer.

I hope this help.

Regards,

Vakhtang.
