I have the following pair of macros defined to handle outbound calls from *.
Rather than specifying full dialstrings in the main body of extensions.conf,
outbound dial commands are made using a macro call as follows:
Macro
(outbound,number_to_dial,callerid_to_present,gateway1,gateway2,gateway3,gate
way4)
The final gateway defined is nearly always a fallback to PSTN if none of the
IAX or SIP gateways are working.
The problem is, its an incredibly unwieldy macro that's horrible to edit if
I want to add a new gateway to the thing. Looking through the documentation
for macro programming, I couldn't find the equivalent of a 'shift'
statement
you'd find in other programming languages.
Can a kind soul suggest how I might tidy it up?
Thanks in advance.
[macro-outbound]
; ${ARG1} Number
; ${ARG2} Caller ID
; ${ARG3,4,5,6} Outgoing gateways in order of use
exten => s,1,GotoIf($["${ARG2}" = ""]?4)

exten => s,10,GotoIf($["${GATEWAY}" = "voip2"]?18)
exten => s,11,GotoIf($["${GATEWAY}" = "voip3"]?16)
