Chapter 5 IP telephones setup and configuration 55

Local mode indication

When an IP telephone is in local mode, a message is displayed on the phone to indicate the local mode state to the user. The default setting is Local Mode.

To change local mode indication

1In Element Manager, navigate to Configuration > Resources > Telephony Resources.

2On the Modules panel, locate the Module type column and select the IP Sets row (see the figure Telephony Resources panel, IP and App Sets on page 54).

3On the Details for Module subpanel, select the IP Terminal Global Settings tab.

4The Advertisement/Logo field specifies the message that provides local mode indication. Change as required.

IP telephone codec and jitter settings

When the IP telephones are operating in local mode, codec and jitter settings are set on a phone-by-phone basis. Configure the settings to meet the requirements of the local SRG environment. They do not have to be the same as the main office settings (in contrast to the QoS settings for the VoIP trunks; see QoS settings (codec, jitter buffer, and related items) on page 70).

To enter codec and jitter settings for IP telephones in local mode

1In Element Manager, navigate to Configuration > Resources > Telephony Resources.

2On the Modules panel, locate the Module type column and select the IP Sets row (see the figure Modules panel, IP & Application Sets on page 56).

3On the Details for Module subpanel, select the IP Terminal Global Settings tab. The fields related to QoS are on the right side of the panel.

4Enter the appropriate values.
