I have been getting a lot of calls from users saying copying files opening files across the VPN tunnel is really slow. At the CA office we have a 3meg connection 2 bonded T1 line. <br />
<br />
Connectec back to datacenter now at the CA office we have about 20 VOIP phone that connect to a virtal PBX by nextiva and they are also saying the phones are chopping up when making phone calls<br />
<br />
but the it takes them for ever to open up file across the VPN tunnel <br />
could it be with don't have enough Bandwith for that office <br />

the offices are connected CA office has a Cisco 2811 router that connect to a ASA 5505 at the Datacenter

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
