Private Name commented on ASTERISK-26063:
-----------------------------------------

the code is:
[setcodec]
exten => s,1,Set(SIP_CODEC=${MASTER_CHANNEL(CODEC)})
exten => s,n,Set(SIPCALLID=${PJSIP_HEADER(read,Call-ID)})
exten => s,n,Verbose(0,WE ARE USING ${SIP_CODEC} FOR "${SIPCALLID}")
exten => s,n,Return

executed from 
exten => _X.,n,Dial(PJSIP/${CODEC}-outbound/sip:${DID}${EXTEN}@${Target},,M(short^${EXTEN:-11}^${CALLERID(num)})${C${recvip}}b(setcodec,s,1))

the code executes fine

> I run the code below inside a b(handler) parameter in the Dial function.
> The code is excuted but it does not return the header Call-ID, which I need to capture for billing purposes. I mean on the outbound channel. In the old SIP channel, there was a variable that held that information. No it is empty, and I guess the code below should read the header in question.
> exten => s,n,Set(SIPCALLID=${PJSIP_HEADER(read,Call-ID)}
