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
Can you breifly explain cisco devices need to install in two offices ? what are the WAN connections need for redundancy in addition to T1 line? ?( do i need hsrp/vrrp) what is the best cisco device including VPN and VOIP ? what about firewall and VLAN ?
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.
