I was going through the script this afternoon, and have a couple of
questions:

1. Why use “>” instead of “=” to compare the extension with “SIP”?

exten => s,n,Gotoif($[“${EXTEN}” > “SIP”]?start)

2. According to www.voip-info.org/wiki/view/Asterisk+cmd+Wait, Wait
only takes one parameter, while WaitExten() can take “m”, which plays
music on hold: Is the wiki out of date and you are using a more recent
version of Asterisk than the 1.4 I have?

exten => s,n,Wait(9,m)

Thank you.
