Forum Post: RE: SIP Instant Messaging via Dialogic HMP

Yes, it seems to be working now. Here is my code: GC_PARM_BLKP parameterBlock = nullptr; GC_PARM_BLKP mimeBlock = nullptr; GC_PARM_BLKP returnBlock = nullptr; char *contentType = "Content-Type: text/plain"; char const *messageBody = message.c_str(); if (gc_util_insert_parm_ref_ex(&mimeBlock, IPSET_MIME, IPPARM_MIME_PART_TYPE, (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), (unsigned long)messageBody) 0 || gc_util_insert_parm_val(&parameterBlock, IPSET_MSG_SIP, IPPARM_MSGTYPE, sizeof(int), IP_MSGTYPE_SIP_MESSAGE) 0 || gc_util_insert_parm_val(&parameterBlock, IPSET_MIME, IPPARM_MIME_PART, sizeof(unsigned long), (unsigned long)mimeBlock) 0) { // log error } else if (gc_Extension(GCTGT_GCLIB_CRN, crn, IPEXTID_SENDMSG, parameterBlock, &returnBlock, EV_ASYNC) != GC_SUCCESS) { // log error } else { // success send! } if (parameterBlock != nullptr) gc_util_delete_parm_blk(parameterBlock); if (returnBlock != nullptr) gc_util_delete_parm_blk(returnBlock); if (mimeBlock != nullptr) gc_util_delete_parm_blk(mimeBlock); I can now see the SIP MESSAGE in WireShark with the Message Body, Content-Type and Content-Length all set correctly. Thanks for your help Leonid!
