Hello,
you can use:
if(is_present_hf("aaa")) ...
Also, it should work like:
if($hdr("aaa") != $null) ...
The is_present_hf() should be slightly faster as it just walks through
the list of headers, not parsing the header body and not returning its
value.
Cheers,
Daniel

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
