I have been testing GMLC server with HLR simulator provided as a part of GMLC. I am running into a SCCP routing issue mentioned below, when I try to send a GMLC request (i.e. curl -X POST 171.10.30.19:8280/restcomm/gmlc/rest?msisdn=8476302000)
15:15:12,147 WARN [SccpStackImpl-SccpStack] (pool-33-thread-1) Rx : MTP-RESUME: AffectedDpc=2

I do notice that a few others encountered this issue and I followed all the configuration suggestions provided in the following links by

The TCAP service bean parameter in ~/RestComm/jboss-5.1.0.GA/server/default/deploy/restcomm-gmlc-server/META-INF/jboss-beans.xml is set to 145 (i.e. GMLC SSN)

<property name="maxDialogs">25000</property >
-->
</bean>
The GMLC code base is from the latest master branch and I am using the ZIP file created by the GMLC server build process. Please let me know, if I am missing something in the configuration or making some mistakes in the test environment itself. I don't see any issues with SCTP association and functioning of M3UA and SCCP initialization. It's something to do with SCCP routing rule configuration that uses primary address config from "routingAddress" config section.
Any help is appreciated.
Thanks and Regards,
Ashok
