E1 or analog line

Hi:
I want to have conference call(meetme) service with asterisk and 30 users.Now do I use 1E1 or 30 analog lines with due attention to high price of E1 line?And which interface card do I use?
Best regards.

I would use an E1 line.

Bye.

I think you will find that 10-12 analog lines will be about the same price as an E1 or T1. If not find a cheaper provider for your T1 or E1.
