Using QPM to Configure QoS for IP Telephony

The QPM IP Telephony application provides a solution for configuring QoS for voice traffic in an AVVID network.

The solution is an IP Telephony wizard that creates voice policies at each network point that requires IP telephony QoS configuration.

Voice policies are policies that contain the QoS properties and traffic rules for each relevant point in the IP telephony network. A voice policy contains a voice role attribute, which specifies the role of an interface, according to its type, function and location on the network, such as, IP phone, Switch to WAN Router. QPM allows you to modify properties and traffic rules of certain voice policies created by the wizard, to suit specific network configurations, as required.

The IP Telephony wizard creates voice policies from voice policy templates which are provided by QPM in the Policy Templates library. These templates follow the IP telephony QoS guidelines, described in the IP Telephony QoS Design Guide:

If the required templates do not exist during IP telephony QoS configuration, they can also be generated by the wizard and stored in the library.

Some templates that are provided by QPM, such as ATM links, might not be used by the IP Telephony wizard.
