jss7 Doesn't send out GSM MAP message

Question

I am using this version of jSS7 via maven

<groupId>org.mobicents.protocols.ss7</groupId>
<artifactId>restcomm-ss7</artifactId>
<version>3.0.1335</version>

I can setup an SCTP link to a Cisco ITP that has E.1 lines on it however when trying to send a SRIforSM gsm map message I see no corresponding MAP pdu in wireshark. I cam only see the ASPUP messages. I'm using jSS7 as standalone.

The following is my code sanitized for conditential data

Answer 1

It is difficult to say exaclty of all reasons that prevent form your messageflow because of SS7 stack demands carefull configuring.

What I can say: you have not configured any SCCP rules / primary addresses. Also it is needed that all SS7 stacks setting fit to the peer stack settings, I can not check it.

To see what happens I can recommend you to check log messages from SS7 stack, it can advice you the root reason.

Also you can take for a prototype this example (and after you can see the messagefow you can adapt the example for your desired messageflow) : https://github.com/RestComm/jss7/tree/master/map/load/src/main/java/org/mobicents/protocols/ss7/map/load
