Sorry guys! Here is what Callcentric tech support provided. They asked me to add 2 settings to SIP.conf:sendrpid=pai
And modify incoming context like so:
exten => s,1,Noop(Trying to add ${SIPCALLID} to the In-Reply-To Header)
exten => s,2,SIPAddHeader(In-Reply-To: ${SIPCALLID})
exten => s,3,Goto(automated_attendant,s,1)

Basically it's all about adding header they support on their end. I do not know if they had to make any config changes on their side or not but seems like it's a supported and legit feature.Now I need to figure out how to figure out when it's a call from office :)))
Thank you,Ivan

Maybe you should ask them how to do this! Maybe you should add a
Diversion header, maybe they don't allow this kind of spoofing at all.
This is a common request from users of SIP trunks and your use case is
legit. If Callcentric does checks on callerid validity and there is a
call to a customer with callerid X, they should be able to use this
callerid X when forwarding to an external device/number.
