[Freeswitch-users] Diversion Header in Dialplan

[Igor Potjevlesch]

Hello freeswitch users,



I’m discovering freeswitch, and I want to understand how to extract and use
the variable « sip_h_Diversion » in the Dialplan.

I know this question has been asked more times in the mailing-list but I
didn’t understand the issue of the diverse topic who evocate this variable.

Also I read the information on the wiki but I wasn’t able to know what I
have to do in my case.



In my Dialplan , I tried to put :



<condition break="on-true" expression="^(?:<sip:)?0(\d{9})((?:@.+)?)$"
field="${sip_h_Diversion}">

                <action application="set" data="sip_h_Diversion=<sip:$1$2"/>

</condition>



to apply a modification on the Diversion Header, but this condition is
unrecognized.

I hope someone could explain me, if I have to extract this variable before
to use it and how to simply do it ?



Thanks,
Bests Regards,
Igor
