About Quality of Service
Your Assistant does not currently support Layer 2 or Layer 3 QoS technology. This is not
currently an issue for remote use of Your Assistant Pro, as support for QoS is variable across
the Internet anyway.
Firewall Configurations
The following firewall configurations are supported:
•
Corporate Firewall Configurations:
-
VPN gateway inside corporate firewall.
-
VPN gateway outside corporate firewall, with firewall set up to trust packets from
VPN.
•
Remote Firewall Configurations:
-
Remote corporate firewall.
-
Client-side firewall (software on computer, or built-in a NAT box or cable/DSL router).
Before Starting Your Assistant
When a VPN connection is established with a corporate network, the corporate LAN issues
a network IP address to the VPN client so the client can behave as if it was directly connected
to the corporate network. This network IP address is different from the computer's NIC IP
address, which can be the computer's IP address on the remote LAN, or the computer's
direct Internet IP address.
Every time your start Your Assistant, it automatically sends its current IP address to the
3300 ICP, so the ICP knows where to send messages and the voice path for incoming calls.
When connecting through a VPN, you must do this step manually before starting Your
Assistant, since the VPN's IP address will likely be dynamically allocated, and be different
every time you connect to the corporate network.
