SIP "Call-ID" field from outbound INVITE

How can I get SIP “Call-ID” field from outbound INVITE?

Which channel driver are you referring to? For example PJSIP allows it using the CHANNEL dialplan function[1] using:

${CHANNEL(pjsip,call-id)}

@jcolp

CHANNEL(pjsip,call-id)

Thanks for your help! Yes, I use PJSIP driver. Before I try to use

channel.PJSIP_HEADER("read,call-id"):get()

but it only for inbound calls.
Now I can finish my cel events.

Have a nice day!
