The other side says that is sending SUSPEND and NOTIFY - SS7 messages which are converted as remote hold and remote retrieval on PRA.
It says those message are coming to my Cisco box (c5350-is-mz.123-18), but the IOS it is not able to interprete them correctly.
I am not seeing this messages in any debugs... Anyone have any idea about ?
Attached is the debug i've got from the other side
