I am required do a lan design for a 500 phone on a non converged environment.
1) There will be 100 phone on each floor.
The phones will be using g729 as preferred codec.
2) Fibre will be used uplink these switches.
3)A 10mb WAN connected will be used to send VOIP RTP and SIGNALLING over a MPLS network towards and SIP based Call manager.
I need to know what switches and router models I can use for this degsign.
Do I need a standalone DHCP server or Can I use the router as DHCP server.?
What QOS consideration is required on switch and the router to optimise the VOIP?
What is model of the LAN I need to follow to achieve a resilient design?
Any feedback is much appreciated.
