[asterisk-users] [Extensions.conf] Interval + discrete extension?

[Vincent]

Hello

	We currently offer extensions 1-4, but we also need to add extension
9 so people can call an operator.

This is the first line for this section in extension.conf:

	exten => _[1-4],1,Verbose(${CALLERID(name)} - ${CALLERID(num)})

Is this the right way to add extension 9?

		exten => _[1-4,9],1,Verbose(${CALLERID(name)} - ${CALLERID(num)})

Thank you.
