We are trying to configure CUCM-Expressway Outbound B2B calling to allow for callback which doesn't work on the normal case since caller ID is DN@"CUCM IP Address" and we need to make it DN@Domain so we are using CUCM normalization script, I'm trying this now in a lab environment but i can't seem to make it work when i check CUCM SDL trace logs i see the header in the SIP invite just the same, i read in some other post on the community that TAC doesn't troubleshoot SIP Normalization Script so i was wondering of anyone can provide some insight regarding this, I'm using the below script configured on the SIP profile applied to Cisco Jabber:
M={}
function M.inbound_INVITE(msg)
local from = msg:getHeader("From")
local newfrom = string.gsub(from,"cucm1pub.example1.com","example2.com")
msg:modifyHeader("From", newfrom)
end
return M
