[asterisk-users] Best way to get 60+ analogue extensions.

[Alex Balashov]

I don't know how good Asterisk's GR.303 support, but you could use DLCs as
well.  However, that's a lot of complexity and (seemingly) immature
functionality liability to achieve the same end you'd get with a channel
bank.  The only benefit is that DLCs are specifically for oversubscription,
whereas on PRIs you'd be doing one timeslot per one POTS line on the trunk
side.
