[asterisk-users] Configure Asterisk to preserve SIP header?

[Scott McNab]

Thanks for your help.

In case anyone is interested, I managed managed to get it to forward the
Call-Info SIP header using the following extension config:

exten => _X.,1,SIPAddHeader(Call-Info: ${SIP_HEADER(Call-Info)})
exten => _X.,2,Dial(SIP/${EXTEN})

Thanks again,
Scott
