Hi,

I am trying to use s7_play to send SCCP over two SCTP M3UA associations, one to each plane of a worker/active-standby system.

The destination system has a single pointcode, sccp traffic is loadshared across the two sctp associations.

I can successfully activate the connections, do ASPUP/ACK ASPAC/ACK on both associations.

The following all works fine -

sending sccp over the first association.

receiving sccp from the far end over either of the two associations.

However if I drop the first association (from the far end equipment), and then try to send sccp, the m3ua module seems to bin the message without using on the second association

I have followed the instructions in the m3ua programmer's manual, section 3.7.1-3, but only for two associations.

This is my s7_play file -
