IPT over IPSEC lines with cisco 2821

[grezzonico]

We are implementing a IPSEC VPN Connection over leased lines using cisco 2821 without AIM-VPN Hardware accelerators.

The line is 2 Mbps and should carry also IPtelephony traffic (4-5 conversations). Will we have problems by mastering the jitter? Since the traffic is devided in small packet, il the 2821 able to handle it accordignly?

Thanks and bye Giorgio

Giorgio,

You should be fine with this configuration. Running voice and video over VPN is certainly a viable solution. It is commonly known as V3PN. Take a look at the V3PN SRND below for best practices, planning, and design tips. As mentioned in this document, IPSEC adds a trivial amount of delay (2 - 5 msec.) to voice deployments.
