DSI send msg to unwanted Point Code

  • ss7.log

    Hi experts,

    I'm developing an application to response the Camel message from OCS System. Here is the flow:

    My application (PC: 4494)  <-------> STP (PC: 4796)  <--------> OCS (PC: 4319)

    Route on GT

    I already received msg from OCS but I saw that the Point Code Present. After that, I tried to send response to the GT of OCS via STP but DSI always send to the PC: 4319. It should be sent to PC of STP (4796) instead of PC: 4319 of OCS.

    Please help me to switch the Dst PC of 4319 to 4796. Thank you very much.

    here is my configure:

  • share your s7_log trace

  • Hi Franck, I have attached the ss7.log. Please help to check , thank you very much.

  • the point code is included in the calling party address of the incoming message.

    i guess your application use the same gt as called party address in the response.

    you can either manipulate the gt in your app, either tune the sccp ext_options settings to ament the PC in the SCCP address.

  • Thank Franck for your suggestion.

    - I have already used GT in my app

    SCCP_GTT_PATTERN 1 0x12 0x00 0x92 0x001204 +8491020335

    SCCP_GTT_ADDRESS 1 0x13 4796 0x92 0x001204 +8491020335

    - The configure SCCP_CONFIG options is 0x010d810e. It mean:

    1: SCPXF_NO_CGP

    0: SCPXF_INCL_CDPC

    1: SCPXF_DEL_CGPC

    1: SCPXF_CG_RTE_GT

    .........

    1: SCPXF_ NO_CALLING_PC

    But outgoing message from my application still goes to PC: 4319

    Which option should be set to ignore the included PC from incoming msg ?
