SIP Header Warnings

You can configure the warning field from a SIP header to display a pop-up message on the phone, for example, when a call transfer failed due to an invalid extension number.

You can display pop-up messages in any language supported by the phone. The messages display for three seconds unless overridden by another message or action.

For a list of supported SIP header warnings, see the article ‘Supported SIP Request Headers' in Polycom Knowledge Base.
