Global SIP Registrations

Overview¶

The SIP Registration section provides a view of the current list of registered SIP users.

It provides two registration views:

Inbound Registrations — Displays active registrations of desk phones or SIP users into ConnexCS.
Outbound Registrations — Displays active registrations from ConnexCS to external SIP endpoints.

SIP Registration has no supplementary documentation or configuration options. This section is intended for viewing the current registration state.

Inbound Registrations¶

Inbound Registrations display active registrations from desk phones or SIP users into ConnexCS.

This view can be used to review the current registration information for SIP users, including their username, IP address, protocol, NAT status, registration timing, and SIP-related details.

Columns¶

The Columns panel allows you to control which SIP Registration fields are displayed.

The available fields include the registration information described in the Inbound Registration Fields and Outbound Registration Fields tables above.

Filters¶

The Filters panel allows you to narrow the displayed SIP Registration records based on available registration fields.

The exact filter conditions available depend on the type of field being filtered.

Custom Settings¶

The Custom Settings panel allows you to customize the appearance of the IP Authentication table.

Theme: The Theme setting controls the visual appearance of the IP Authentication table.
Row Height: The Row Height setting controls the amount of vertical space used for each IP Authentication record.
- Lower row height — Displays more records within the available screen space.
- Higher row height — Provides more spacing between records for easier reading.

These settings affect only the presentation of the IP Authentication list and do not change the underlying authentication configuration.
