Supplementary Services Notes
The SPA9x2 provides native support of a large set of enhanced or supplementary services (also
known as star codes). All of these services are optional. In this section, you can enable or disable
specific supplementary services for users.
A supplementary service should be disabled if
• the user has not subscribed for it
or
• the service provider intends to support similar service using other means than relying
on the SPA9x2.
Most supplementary services are described in ”Vertical Service Activation Codes (Star Codes)”
section on page 69.
• Text Message: SPA9x2 phones can receive and display text messages via SIP according to
RFC3428. Select yes to enable receipt of SIP MESSAGE messages and display of text
from the PROXY.
• Text Message From 3rd Party: select yes to enable receipt and display of text messages from
any third party directly, without proxy involvement.
When this feature is enabled, the phone displays messages up to 255 characters in length. The
message appears on the phone display along with the date and time.
Service providers could use text messages to:
• Send billing information, calling minutes consumed, minutes available
• Include additional text with a call to facilitate call processing
