I need to get value of CALLED_DID header and do some actions in dialplan, but i don't know how.
I've tried to use ${sip_h_CALLED_DID} but it's empty, because have no X- prefix before header name.
Is there any other method to extract value from SIP header?
Please help me, i've read allover the internet but can't find answer.

After reading a ton of material, I came to the conclusion:
Reading of custom header without X- prefix is not possible without modifying of source code.
But this is not acceptable way in my case.
