Isup.mangle
From Yate Documentation
The isup.mangle message is sent by the 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.
