TC-END: No dialog/transaction for id Warning when Sending/Recieving USSD MAP Messages

[Ahmed Khan]

Dear All,

I have implemented a simple USSD client/Server. When i send the invoke processunstructeredSS-Request to Server, what happens is that the Server responds back with SACK returnResultLast processUnstructuredSS-Request with TC-END. Then after some time the Server responds again back again with returnResultLast processUnstructuredSS-Request.

During this process i get the following warnings on my Client:

20615 [pool-1-thread-1] WARN  org.mobicents.protocols.ss7.tcap.TCAPProviderImpl  - TC-END: No dialog/transaction for id: 1

20786 [pool-1-thread-1] WARN  org.mobicents.protocols.ss7.tcap.TCAPProviderImpl  - TC-END: No dialog/transaction for id: 1

20786 [pool-1-thread-1] WARN  org.mobicents.protocols.ss7.tcap.TCAPProviderImpl  - TC-END: No dialog/transaction for id: 1

Can someone please tell me the reason for getting these warnings. Furthermore i have attached the wireshark capture as well.

Looking forward for a positive feedback.

Regards,

Ahmed
