SmartWare Software Configuration Guide 39 • SIP interface configuration
Mode: Interface SIP
Enabling SIP RFC Privacy, Asserted-Identity, & Preferred-Identity headers (RFC 3323/3325)
The following command sequence enables support for the SIP Privacy and Asserted-Identity headers, sending
and receiving of the Privacy as well as the Asserted-Identity headers of RFCs 3323 & 3325. This provides the
required identity to SIP entities. The privacy header suppresses the forwarding of the identity to the final sta-
tion. Handling of the Asserted-Identity header can be configured in the same way as for any other SIP header
using the address-translation command in the SIP interface configuration mode. The privacy header is mapped
to the call-control's presentation indicator property field.
The type of header sent depends on the screening-indicator property of the call-control. When receiving one of
these privacy headers the screening-indicator is also set depending on the received header type.
Mode: Interface SIP
Updating caller address parameters
A SIP User Agent Client (UAC) can use the sip update method for modifying caller-name and caller-number.
These parameters must be included in the P-Asserted-Identity header of the sip update message. This feature is
often required if sip has to interwork with an analog telephone network where the Caller-Id cannot be deliv-
ered together with the call offering. If SmartWare is working as SIP to FXS Gateway, the UAC can send the
update at any time between the initial invite and the final response. The delivered parameters will be presented
to the FXS subscriber during the current or the next ring pause.

[node](if-sip)[if-name]# address-transla-
tion outgoing-call request-uri target-
param call redir
Enables Redirecting Party Number Tunneling
ISDN ‡ SIP: Enables transmission of the target

ters.
