Lets you use compact SIP headers in outbound SIP messages. Select yes or no from the
drop-down menu. If set to yes, the Linksys IP phone uses compact SIP headers in
outbound SIP messages. If set to no, the Linksys IP phone uses normal SIP headers. If
inbound SIP requests contain compact headers, Linksys IP phone reuses the same compact
headers when generating the response regardless the settings of the <Use Compact
Header> parameter. If inbound SIP requests contain normal headers, Linksys IP phone
substitutes those headers with compact headers (if defined by RFC 261) if <Use Compact
Header> parameter is set to yes.
