The device supports the interworking of SIP Via headers between SIP entities. For the
outgoing message sent to a SIP entity, the device can remove or retain all the Via headers
received in the incoming SIP request from the other side. Employing IP Profiles, you can
configure this interworking feature per SIP entity, using the IpProfile_SBCKeepVIAHeaders
parameter (see ''Configuring IP Profiles'' on page 423).
29.9.13 Interworking SIP User-Agent Headers
The device supports the interworking of SIP User-Agent headers between SIP entities. For
the outgoing message sent to a SIP entity, the device can remove or retain all the User-
Agent headers received in the incoming SIP request/response from the other side.
Employing IP Profiles, you can configure this interworking feature per SIP entity, using the
IpProfile_SBCKeepUserAgentHeader parameter (see ''Configuring IP Profiles'' on page
423).

The device supports the interworking of SIP Record-Route headers between IP entities.
For the outgoing message sent to a SIP entity, the device can remove or retain all the
Record-Route headers received in the incoming SIP request/response from the other side.
Employing IP Profiles, you can configure this interworking feature per SIP entity, using the
IpProfile_SBCKeepRoutingHeaders parameter (see ''Configuring IP Profiles'' on page 423).

multiple SDP answers) between IP entities. The device can either use the same To-header
tag value for all SDP answers sent to the SIP entity, or send each SDP answer with its
original tag. Employing IP Profiles, you can configure this interworking feature per SIP
entity, using the IpProfile_SBCRemoteMultipleEarlyDialogs parameter (see ''Configuring IP
Profiles'' on page 423).
