Hi, It is not clear what you are trying to achieve. If you want to set the diversion header on the b-leg, you need to use the export application instead of set. Also, you are using break-on-true, which requires a bridge call or an extension with continue=true to be useful. If the export does not work, can you please post your full extension and the corresponding freeswitch debug log?

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 <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, Alexis Devin
