Asterisk 1.4.12
I wish to extract some custom headers from a SIP REFER message but am unable
to do so. However I can extract them from an INVITE. The code is:
exten => _.,n,Set(custom-id=${SIP_HEADER(custom-id)}) ;
exten => _.,n,Set(custom-valid=${SIP_HEADER(custom-valid)}) ;
Examples of the INVITE (works) and REFER (doesn't) messages are below.

Is this a limitation of Asterisk or am I missing something?

It's something that I think would be a good feature though. /O
