I think if I set a $var() in "INVITE", it will be gone when I receive the failure response. $sht() seems able to last long but it will be accessed by all processes which might include ones not belonging to the same dialog. I wonder if somebody would give me some suggestions here to handle such situations. Does Kamailio provide a mechanism to set up a parameter with a life span of the entire dialog? Thanks.</div><div id="yui_3_16_0_ym19_1_1467900347990_5023" dir="ltr"><br></div><div id="yui_3_16_0_ym19_1_1467900347990_5023" dir="ltr">Regards,</div><div id="yui_3_16_0_ym19_1_1467900347990_5023" dir="ltr">Jay</div><div id="yui_3_16_0_ym19_1_1467900347990_5023" dir="ltr"><br></div><div id="yui_3_16_0_ym19_1_1467900347990_5023" dir="ltr"><br></div></div></body></html>
