Hi Ben,You can specifically check the Open Source list for Unified CM depending upon what version you are interested in:https://www.cisco.com/c/en/us/support/unified-communications/unified-communications-manager-callmanager/products-licensing-informa...
Sam,If you want to change the headers in the same 'outbound_INVITE' headers, then just add additional header manipulations in the function you are working on.Mark
Hi Sam,gsub is greedy, so unless you capture the LHS, it will disappear after the substitution. I would try:local b = string.gsub(from, "@10.10.10.1>", "@A.B.C.D>")Mark
