I am installing Asterisk in a small office with just 4 lines and 8 Extensions.
I have two choices from my local telco (Fairpoint):
1) Old School ISDN BRI lines which I would connect to Asterisk with a OpenVOX B200P 2) Telco supplied SIP trunks over a service called EDIA which is 1MB ethernet over several pair of copper lines.
The ISDN BRI solution is less than 1/2 the price of the SIP solution.
Are there any risks or technical pitfalls I should worry about if I go with the ISDN BRIs ?
