51 call attempts to initiate an association to a peer SCTP
53 The call operates similarly to
55 but it also provides the ability to specify multiple destination
56 addresses for the peer.
57 This allows a fault tolerant method
58 of initiating an association.
59 When one of the peers addresses
60 is unreachable, the subsequent listed addresses will also be used
61 to set up the association with the peer.
63 The user also needs to consider that any address listed in an
65 call is also considered "confirmed".
66 A confirmed address is one in
67 which the SCTP transport will trust is a part of the association
68 and it will not send a confirmation heartbeat to it with
71 If the peer SCTP stack does not list one or more of
72 the provided addresses in its response message then
73 the extra addresses sent in the
75 call will be silently discarded from the association.
