Hi,

 

If I normally receive a INVITE that has a header ‘aaa’ with value ‘bbb’, but it’s possible that some INVITEs don’t have this header.

How do I determine in the config file if the header exists?

To check the value of the header I do if($hdr(aaa) == "bbb"). But what if the header doesn’t exist?

 

Cheer,

Allen
