[Freeswitch-users] Delete previously appended header for the bridged leg

Hi, I issue this command via python ESL: " originate{origination_uuid=bla}{sip_h_X-HEADER1=VALUE1}sofia/gateway/gateway1/to_uri1 &bridge({sip_h_X-HEADER2=VALUE2}sofia/gateway/gateway1/to_uri2) " The problem I have is that HEADER1 is still existent in the bridged leg. I have tried adding &unset(sip_h_X-HEADER1) without success. Also I've tried with [] as said here [1], without succes. What would be the solution to remove the sip_h_X-HEADER1 for the bridged party?
