Hello, https://wiki.freeswitch.org/wiki/Variable_sip_copy_custom_headers I'm not sure but this link may help you. On Thu, Aug 10, 2017 at 2:24 PM, Lợi Đặng <loi.dangthanh@gmail.com> wrote:
Hi guys, I have a simple call scenario: *Caller -> FS -> Callee* Callee answer the call with an additional header called X-MyVar in 200 OK. I'm trying to store that value only for reporting via CHANNEL_HANGUP_COMPLETE - event socket.
I'm retrieving that custom header by looking at ${sip_rh_X-MyVar} via *execute_on_answer* on B leg, and it's fine. But I'm unable to export it to the A leg. Here's my dialplan:
*<extension name="logvar"> <condition field="destination_number" expression="^logvar$"> <action application="export" data="myvar=${sip_rh_X-MyVar}"/> </condition></extension><action application="bridge" data="{execute_on_answer=execute_extension logvar XML external}sofia/external/${destination_number}"/>*
I don't want X-MyVar header to be passed to Caller, so I have to export the variable. But when CHANNEL_HANGUP_COMPLETE fires, the variable *variable_myvar* present only in the outbound B leg. Look like my export did not work. Note that I have some upstream exports from A leg to B leg in normal XML dialplan and they're all fine.
Below is my fs_cli log: 192.168.1.100 is my FS.
*Dialplan: sofia/external/400@192.168.1.100:5060 <http://400@192.168.1.100:5060> Action export(myvar=${sip_rh_X-MyVar})2017-08-10 17:27:29.958572 [NOTICE] switch_core_session.c:2913 Execute export(myvar=${sip_rh_X-MyVar})EXECUTE sofia/external/400@192.168.1.100:5060 <http://400@192.168.1.100:5060> export(myvar=598c35116ee949.25824485)2017-08-10 17:27:29.958572 [DEBUG] switch_channel.c:1296 EXPORT (export_vars) [myvar]=[598c35116ee949.25824485]*
Not sure what I'm missing in this case. Any help would be appreciated. rgds, Loi Dang
