Sip header manipulation for PJSIP

[lgaetz (Lorne Gaetz)]

There are cleaner ways of manipulating SIP headers on outgoing trunk calls, and using the override file is to be avoided whenever possible. I recommend you use the native header gosub functions with macro-dialout-trunk-predial-hook

Need to add SIP header to outbound calls on PJSIP trunk

There are channel agnostic, native FreePBX subroutines for this. Use a dialplan hook to call like this: [macro-dialout-trunk-predial-hook] exten => s,1,NoOp(Entering user defined context [macro-dialout-trunk-predial-hook] in extensions_custom.conf) exten => s,n,GoSub(func-set-sipheader,s,1(X-Tenant,somename.to.match)) exten => s,n,MacroExit()
