SIP Settings
Before you start creating extensions for SIP phones or SIP trunks, you should review options configured for SIP devices.
To configure common options used for all SIP devices (phones and trunks), perform the following steps:
- Open the UCx Web-based Configuration Utility
- From the PBX tab, select PBX Configuration
- From the left side column, select SIP Settings
- Review the configured defaults
- If you made any changes in the settings for SIP phones, press the Submit Changes button to save the configuration
You should review and change the default values for some of the options as required:
NAT Settings
Update the NAT specific configuration options to match your network configuration.
Audio Codecs
Video Codecs
Media & RTP Settings
Notification & MWI
Registration Settings
Jitter Buffer Settings
Advanced General Settings
If you want to change the default port number (5060) that is used by the UCx system for communication with SIP phones (for example for security reasons), enter the desired port number in the Bind Port field.
