I'm putting in a 5 site Qwest MPLS network - T1 ports and the remotes and 3 x T1 at the host. I'll be using CISCO1841-T1 at the remote sites and a Cisco 2821 with qty. 2 VWIC2-2MFT-T1/E1 at the host. Cisco pre-sales told me that Cisco IOS Base was not sufficient and that I would need Cisco 2800 SP SERVICES 1 (S28NSPSK9-12411XW). I cannot find any documentation to back this up. Is this so? Thanks for the help.
