asterisk users - Sep 2010 - Requirement or just Best Practice

Hi gang,

            I'm in the process of documenting an 1100 line IVR dialplan.  In
this dialplan I have almost 300 Set commands.  The numeric ones are simple;

Exten => s,1,Set(TYPE3=0)

My question is about the Alpha/Text values;

If I do

Exten => s,1,Set(beep=beep)

Or 

Exten => s,1,Set(beep="beep")

Then 

Exten => s,n,playback(${beep})

It seems that I get the same result (beep plays)

I'm on 1.4.30;  Keeping in mind that 1.4 EOL's in 14 months, should I
"standardize" my "Alpha sets" to the second instance or does
it matter
(regarding 1.6/1.8)?

 

Thanks in Advance

Danny Nicholas
