[Freeswitch-users] Unset variable in dialstring

[Vallimamod Abdullah]

Hi,

For sip headers you need to set an empty value to remove them: {sip_h_Privacy=} 

or before the bridge: 

<action application="export" data="_nolocal_sip_h_Privacy="/> 

the "_nolocal_" (or "nolocal:") prefix tells freeswitch to set the var only on b-leg.

Hope this helps.



Best Regards,
