to Hangup the Call i am using the Following Code :
pj_status_t status;
pjsip_tx_data *tdata;

 status = pjsip_dlg_create_request(dlg, &pjsip_bye_method, -1, &tdata );
 status = pjsip_dlg_send_request ( dlg, tdata, NULL,NULL);

Is there anything missing ? Why is the application crashing after
sending the hangup

Thx
