View source for Isup.mangle

The '''isup.mangle''' message is sent by the [[ISUP Mangler|ISUP Mangler]] module allowing to modify the parameters of an ISUP message passing through the STP

===Parameters===

;message-type
:Type of the intercepted message 
;protocol-type
:Keyword indicating the encoding standard: itu-t, ansi 
;address
:Name of the mangler component generating the message and Circuit Identification Code 
;opc
:Originating Point Code of the message (numeric) 
;dpc
:Destination Point Code of the message (numeric) 
;sls
:Signalling Link Selection in the message label 
;slc
:Signalling Link Code of the link the message was received on 
;cic
:Circuit Identification Code for the message 

Other parameters are taken from the message and are similar to those of an incoming ISUP call but have no prefix.

'''Notes'''

* The OPC, DPC, SLS and CIC of the message cannot be changed as that will break basic SS7 and ISUP assumptions.

* You must not alter the IAM continuity check flags as it would cause the test to fail or the loopback to be left in place indefinitely.
