RE: SIP Instant Messaging via Dialogic HMP

Hi again. I have been trying to send an out of session SIP message as you described using this code:

    bool success = false;
    GC_PARM_BLKP parameterBlock = nullptr;
    GC_PARM_BLKP mimeBlock = nullptr;
    GC_PARM_BLKP returnBlock = nullptr;

    char *contentType = "Content-Type: text/plain";
    char *messageBody = "Message body goes here";

    char *userAgent = "User-Agent: VoiceGuideHMP";
    std::ostringstream contactUriSS;
    contactUriSS << "Contact: <sip:" << contactUri << ">;methods=\"INVITE, INFO, MESSAGE, SUBSCRIBE, BYE, CANCEL, NOTIFY, ACK, REFER\"";
    const std::string formattedContactUri = contactUriSS.str();

    if (gc_util_insert_parm_val(&parameterBlock, IPSET_MSG_SIP, IPPARM_MSGTYPE, sizeof(int), IP_MSGTYPE_SIP_MESSAGE) < 0 ||
        gc_util_insert_parm_ref_ex(&parameterBlock, IPSET_SIP_MSGINFO, IPPARM_REQUEST_URI, static_cast<unsigned long>(formattedContactUri.length() + 1), const_cast<char *>(formattedContactUri.c_str())) < 0 ||
        gc_util_insert_parm_ref(&parameterBlock, IPSET_SIP_MSGINFO, IPPARM_SIP_HDR, (strlen(userAgent) + 1), userAgent) < 0 ||
        gc_util_insert_parm_ref_ex(&mimeBlock, IPSET_MIME, IPPARM_MIME_PART_TYPE, static_cast<unsigned long>(strlen(contentType)) + 1, contentType) < 0 ||
        gc_util_insert_parm_val(&mimeBlock, IPSET_MIME, IPPARM_MIME_PART_BODY_SIZE, sizeof(unsigned long), strlen(messageBody)) < 0 ||
        gc_util_insert_parm_val(&mimeBlock, IPSET_MIME, IPPARM_MIME_PART_BODY, sizeof(unsigned long), reinterpret_cast<unsigned long>(messageBody)) < 0 ||
        gc_util_insert_parm_val(&parameterBlock, IPSET_MIME, IPPARM_MIME_PART, sizeof(unsigned long), reinterpret_cast<unsigned long>(mimeBlock)) < 0)
    {
        // log error
    }
    else if (gc_Extension(GCTGT_GCLIB_CHAN, ldid, IPEXTID_SENDMSG, parameterBlock, &returnBlock, EV_ASYNC) != GC_SUCCESS)
    {
        // log error
    }
    else
    {
        success = true;
    }

    if (mimeBlock != nullptr) gc_util_delete_parm_blk(mimeBlock);
    if (parameterBlock != nullptr) gc_util_delete_parm_blk(parameterBlock);
    if (returnBlock != nullptr) gc_util_delete_parm_blk(returnBlock);

    return success;

However this is failing when gc_Extension() is called. I retrieve error info and am logging this:

[2016-03-01 11:08:06] (0x00000d50) [Err] gc_Extension() failed in Extension_SipMessage() with LDID 3
[2016-03-01 11:08:06] (0x00000d50) [Err] gc_ErrorInfo() results - GCValue: 68, GCMessage Invalid parameter, CCLibID: 8, CCLibName: GC_H3R_LIB, CCLibValue: 48, CCLibMessage: IPERR_INVALID_ID.

In the Dialogic RTF logs I see this:

I am wondering what I am doing wrong that would mean it was saying "hCrn=0 is invalid" when I am specifying GCTGT_GCLIB_CHAN.

Do you see any issues with my code? Should I be using IPPARAM_CONTACT_URI rather then IPPARAM_REQUEST_URI?

Thanks
