Redundant VOIP

Hello Geeks

I have a requirement to connect two offices in same company  with 60  users each through a t1 line to support internet access /file server and  VOIP. network should be redundant (24*7 ) operations similar to a call  center . should have VPN access and VLANS.  prefer cisco devices

If t1 line or a router fails there should be automatic failover method

Cheers

Hi

I think using PPP multilink can help you in t1 failure. And you can use CME redundancy in case of router fail.

Hi

You can use two two Cisco ISR router at each site, they are good for VOIP design.  I think when you terminate your WAN on both the routers in the site, The WAn redundany will be taken care by routing protocol. And voip redundancy will be taken care by CME configuration.
