Menu settings Overview, Compact, Wide, Zoom In, and Zoom Out can be used to change the arrangement of all device boxes and text sizes of all message snippets. The View menu provides options to show or hide additional information in message snippets (Duplicates, URIs, Protocols, IPs, MACs, Codecs, and Absolute Time) and few others that influence device boxes as well (Pin Devices, Unwind Messages).

A pop-down menu with predefined checkboxes will be shown. 
 The following menu items are available:

URIs (Unified Resource Identifier) are not shown by default. When checked, they will be shown in the first line of all message snippets, see example below. This option can be useful if the URI user and/or domain part contains helpful information, i.e. phone number, etc.

When checked (default), the protocol used to transport the message will be shown in the first line of all message snippets, see example below. Typical values are UDP and TCP. This option can be used to solve general network problems.

When checked (default), the source IP addresses of the sending and the destination IP addresses of the receiving VoIP device will be shown in all message snippets, see example below. This option can be used to verify the correct IP routing between VoIP devices, also IP spoofing can be detected.

When checked (default), the source MAC addresses of the sending and destination MAC addresses of the receiving VoIP device will be shown in all message snippets, see example below. This option can be used to verify whether a VoIP device uses the correct network interface.

<WRAP center box 620px> MAC Example </WRAP>

When checked (default) and the raw VoIP message contains a SDP (Session Description Protocol) header, the codec information will be displayed in all message snippets, see example below. This is the case for messages establishing a media session, e.g. SIP INVITE.

When checked (default) and the VoIP message can be associated with a time stamp, the time information will be displayed in all message snippets. This option can be used to detect delays in VoIP environments.


When checked (default), device boxes may appear duplicated. This intended behavior simplifies the readability of the VoIP message flow, i.e. message snippets are placed exactly between two device boundaries, see example below.

<WRAP left box 320px> Checked</WRAP> <WRAP right box 300px> Unchecked</WRAP>

This option is not checked by default. When checked, device boxes will be locked on top of the message window. This option can be useful when scrolling through large pages or small browser windows respectively.
