Hi there Patrick, I would suggest you raise an issue over on the GitHub project (https://github.com/RestComm/gmlc), to get an answer on something like this. — gsaslis, Jan 02 '18 at 10:07

I see quite a few issues in the raised question, albeit I think your problem is in jboss-beans.xml file (will get there later), it's important to clarify them as they could potentially be cause of problems.

1) SSN should be 145 as for specifications, and you got it right in Restcomm GMLC's configuration files, but in the image it appears as 147 (which is not appropriate, as that is the SSN for gsmSCF, not for GMLC). Are you sure the MNO has 145 and it's only a typo in the image?

2) MSC SSN is 8, not 6 as you put it in mscssn value at GmlcManagement_gmlcproperties.xml. Modify that to 8 please.

3) Are you sure about the routingContext and networkAppearance values or did you just copied them from the simulator profile?

Having that in mind, your main problem most likely reside at the following two configuration files:

1) Check $GMLC_HOME/jboss-5.1.0.GA/server/default/deploy/restcomm-gmlc-server/META-INF/jboss-beans.xml TCAP Service section... it should look like this:

    <!-- ==================================================================== -->
    <!-- TCAP Service -->
    <!-- ==================================================================== -->
    <bean name="GMLC_TcapStack" class="org.mobicents.protocols.ss7.tcap.TCAPStackImpl">
        <constructor>
            <parameter>TcapStack</parameter>
            <parameter>
                <inject bean="GMLC_SccpStack" property="sccpProvider" />
            </parameter>
            <parameter>145</parameter>
        </constructor>
        <property name="persistDir">${jboss.server.data.dir}</property>
        <!--
        <property name="dialogIdleTimeout">60000</property>
        <property name="invokeTimeout">30000</property>
        <property name="maxDialogs">25000</property >
        -->
    </bean>

First, are you sure 145 is there? Then and again, as pointed out in 1), are you sure the MNO and your configuration are concordant?

2) Your routing rule configuration at SccpStack_sccprouter2.xml might lead you to problems, set pc and ssn values to 0 in patternSccpAddress, like this:

<rule>
    <id value="1"/>
    <value ruleType="Solitary" loadSharingAlgo="Undefined" originatingType="RemoteOriginated" mask="K" paddress="1" saddress="-1" networkId="0">
        <patternSccpAddress pc="0" ssn="0">
            <ai value="18"/>
            <gt type="GT0100" tt="0" es="2" np="1" nai="4" digits="237694000089"/>
        </patternSccpAddress>
    </value>
    <id value="2"/>
    <value ruleType="Solitary" loadSharingAlgo="Undefined" originatingType="LocalOriginated" mask="K" paddress="2" saddress="-1" networkId="0">
        <patternSccpAddress pc="0" ssn="0">
            <ai value="16"/>
            <gt type="GT0100" tt="0" es="1" np="1" nai="4" digits="*"/>
        </patternSccpAddress>
    </value>
</rule>

Please keep us posted, good luck and best regards, Fernando Mendioroz

Hello,I have applied all the steps you specified, and the link between the gmlc and the STP server is up but now i get this error when i try to make a map ati request "15:27:06,574 ERROR [M3UAManagementImpl] (SLEE-EventRouterExecutor-4-thread-1) Tx : No AS found for routing message TransferMessage: {528=Protocol opc=89 dpc=42 si=3 ni=2 sls=3} " – NDZIE Patrick Joel Jan 23 '18 at 14:31
Hello again Fernando, after looking at the github repository of restcomm gmlc i found that the latest binary release i use is from 20th september 2016, and there is no newest one available, and the issue i'm facing where already raised in Restcomm Gmlc google group in 2016. There fore i suppose the issue has been handled since there. Can you please provide me the latest binary release? – NDZIE Patrick Joel Jan 23 '18 at 19:36
Will i have to install it from the source code as specified in github? – NDZIE Patrick Joel Jan 23 '18 at 19:39
Hi @NDZIEPatrickJoel, You can always find latest releases here: https://github.com/RestComm/gmlc/releases You may do it both ways. Anyway, this seems to be a configuration issue. Did you make the changes with the GMLC down, then restarted it? You need to stop the JBoss server, then do the modifications and after that start it again, so the new parameters are taken. – Fernando Mendioroz Jan 24 '18 at 17:16
Hello @Fernando Mendioroz i have successfully set up the gmlc server and the link between, the STP and the GMLC is up, but when i try a map ati request (curl -X POST http://172.21.75.34:8080/restcomm/gmlc/rest?msisdn=237699947943 ) I get this error **The server does not support the functionality needed to fulfill this request ()** But when i try the same request with the dummy msisdn **19395550113** i have a response. What does it means please? – NDZIE Patrick Joel Jan 31 '18 at 14:34
This is what i get in the server log **2018-01-31 17:03:15,584 ERROR [org.mobicents.protocols.ss7.m3ua.impl.SignalingNetworkManagementHandler] (Thread-37) Rx : DUNA =DUNA Params(AffectedPointCode pointCode=[78] mask=[0], ) But AppServer Functionality is not As. Sending back ErrorCode.Unexpected_Message** – NDZIE Patrick Joel Jan 31 '18 at 16:15
Hi @NDZIEPatrickJoel, glad you managed to get the links up. There's nothing wrong with the command, it should work. But for the server log you are providing, you are getting a DUNA (Destination UNAvailable). Something is wrong between the GMLC and the core network. Another problem you might get is that GMLC GT must be permitted in the HLR for performing ATI, otherwise you will get an ATI not allowed error. Do you have a pcap trace to look at? – Fernando Mendioroz Feb 01 '18 at 21:52
Hello Fernando, here are some lines that i captured with wireshark. 0.498697613 192.168.212.185 -> 172.21.75.34 SCTP 70 HEARTBEAT 0.498753415 172.21.75.34 -> 192.168.212.185 SCTP 70 HEARTBEAT_ACK 1.115210818 192.168.212.185 -> 172.21.75.34 SCTP 70 HEARTBEAT 1.117412789 172.21.75.34 -> 192.168.212.185 SCTP 70 HEARTBEAT_ACK 1.735153820 192.168.212.185 -> 172.21.75.34 SCTP 70 HEARTBEAT 1.735212449 172.21.75.34 -> 192.168.212.185 SCTP 70 HEARTBEAT_ACK (172.21.75.34 is the GMLC IP and 192.168.212.185 is the STP IP) – NDZIE Patrick Joel Feb 06 '18 at 17:35
Hello Fernando, Can you please provide me a working configuration for Restcomm GMLC and HLR? Maybe it will help me figure out what i am doing wrong. tshark trace only shows HEARTBEAT and HEARTBEAT_ACK, but no message is initiated by the GMLC. – NDZIE Patrick Joel Feb 07 '18 at 14:37

@NDZIEPatrickJoel I'm sorry but I cannot publicly give neither configuration nor traces of customer's GMLC live deployments, among many, for non-disclosure agreements between parties. I could give you a simple configuration case with scrambled numbers of SS7 credentials of a real life deployment, but anyway I'd need authorization from the executive team. Please, send an email to info@telestax.com or consider acquiring professional services and we'd gladly help you to sort this out. Or refer to our online documentation: https://www.restcomm.com/docs/core/ss7/SS7_Stack_User_Guide.html#_managing – Fernando Mendioroz Feb 13 '18 at 06:49
