you can see the usual "trying - your call is important to us" in the dialog.
Anyhow, for some reason SER occasionally attempts to sent the ACK to itself,
which causes a looping condition. The last ACK shown is the start of the
looping condition.<BR><BR>It only happens on occasion. SER should have
consumed the ACK rather than attempted to forward it.<BR><BR>Can anyone
explain this?<BR><BR>Regards,<BR>Paul<BR><BR>IP
