PK50722: RFC3263- Session Initiation Protocol (SIP): Locating SIP Servers

APAR status

• Closed as program error.

Error description

• The Session Initiation Protocol (SIP) uses DNS procedures to
  allow a
     client to resolve a SIP Uniform Resource Identifier (URI)
  into the IP
     address, port, and transport protocol of the next hop to
  contact.  It
     also uses DNS to allow a server to send a response to a
  backup client
     if the primary client has failed.  RFC 3263 describes
  those DNS
     procedures in detail.
