[Freeswitch-users] Dropping the Subject: header

[Steven Ayre]

Hmm,

Can you see whether sip_h_Subject is on the A-leg (you can use <action
application="info"/> to log all the variables on the channel)?

If is is, also try:
<action application="export" data="sip_h_Subject=${sip_h_Subject}"/>
although I didn't think this was required if the variable was already
set with the same name.
