Patton electronic SmartNode 4110 Series manual SIP Diversion Header

SmartWare Software Configuration Guide 39 • SIP interface configuration

It is possible to configure the sip interface to wait for the caller-name, caller-number or both parameters before routing the call. If the caller-address parameters are sent with sip update and the call will be forwarded to a net- work where these parameters must be present at call setup time (ISDN), this wait-service must be enabled.

Note The SIP interface of the call-router must be configured to take the caller addresses parameters for incoming calls from the P-Asserted-Identity header. See “Enabling SIP RFC Privacy, Asserted-Identity, & Preferred-Identity headers (RFC 3323/3325)” on page 448 for more information.

SIP Diversion Header

SmartWare supports the SIP Diversion Header for transmitting redirecting information over SIP according to draft-levy-sip-diversion-08. Sending and receiving of the header can be configured independent of each other. Even though the Diversion Header standard would allow appending a header for each diversion occurred in the network, SmartWare only records the last and the first diversion. If only one Diversion Header is attached to the INVITE request, then it represents the last diversion.
