Hello,

can you paste the header here and how you used it in the config? Have tried to print it with xlog or in some other expression? Also, in what kind of routing block you try to get it?

Cheers,
Daniel

Hello,

How to get ISUP cause in the 'Reason' header field of SIP error reply ?

I've tried a few ways but it did not work
@message.header.Reason.params["cause"]

or
$hdr(Reason) gives null

Thanks,
