Hi Community, I have a question: according to wiki: https://freeswitch.org/confluence/display/FREESWITCH/NAT+Traversal parameter <param name="nat-options-ping" value="true"/> may be assigned to profile. But may it be assigned to particular user ? I tried to do this like that: <user id="pbxuser"> <params> <param name="password" value="PwgEn123"/> </params> <variables> <variable name="toll_allow" value="domestic,international,local"/> <variable name="accountcode" value="1000"/> <variable name="user_context" value="mypbx"/> <variable name="callgroup" value="techsupport"/> <variable name="sip-force-expires" value="180"/> <variable name="sip-force-contact" value="NDLB-connectile-dysfunction"/> <variable name="nat-options-ping" value="true"/> </variables> </user> But freeswitch does not send option to registered endpoint. Thanks ! -- Best regards, Volodymyr
