Examples of org.zoolu.sip.header.ContactHeader

org.zoolu.sip.header.ContactHeader
SIP Header Contact. The Contact header field provides a SIP or SIPS URI that can be used to contact that specific instance of the UA for subsequent requests. The Contact header field MUST be present and contain exactly one SIP URI in any request that can result in the establishment of a dialog (i.e. INVITEs).
Note: for backward compatibility with legacy implementations the date format in 'expires' parameter is still supported although it has been deprecated in RFC 3261.
