5 In the FIREWALL, set up a LAN-to-LAN rule to block traffic between the

guest subnet (DHCP Pool) and the corporate subnet (IP Alias subnet).

Note: If branch tunnels are being used, the policies on these tunnels should

exclude the guest subnet.

Preventing heavy data traffic from impacting telephone calls

To ensure voice quality during heavy data traffic, bandwidth needs to be reserved

for voice traffic.

1 Determine your actual WAN up-stream bandwidth by connecting to a web site

such as http://myvoipspeed.visualware.com/.

2 On BANDWIDTH MANAGEMENT / Summary, activate WAN bandwidth

management, and fill in your actual uplink speed in the WAN Speed field..

3 On BANDWIDTH MANAGEMENT / Class Setup, add a WAN subclass, and

reserve sufficient bandwidth based on the number of telephones, for Protocol

ID 17 (UDP Traffic).

The amount of bandwidth should be based on a reasonable peak number of

simultaneous calls, and the data rate needed by the IP telephony CODECs.

Setting Up a Remote Office with a UNIStim IP Telephone

For a remote office with a PC, and a UNIStim IP telephone behind a Business

Secure Router, Client Emulation is the recommended method to connect to the

main office.

1 At the main office Contivity Client Server, establish two user accounts - one

for the telephone, and one for the PC.

2 On the remote office Business Secure Router, do the following:

Under WAN / WAN IP, ensure that Network Address Translation is set to

SUA Only (default). Also ensure that the Gateway IP address is set (not

0.0.0.0).

Under VPN / Summary, create an entry for the IP telephone client tunnel.

(Contivity Client, Active, Keep Alive). Fill in the IP address of the Contivity

Client Server, and the name and password of the telephone set user account.
