Hi,

I'm wondering what the best option to obtain a high availability
asterisk server is.

I currently use a TE410P (4 x E1) card.

I'm thinking of 2 different solutions:

- 2 servers configured with Heartbeat + DRBD (drbd mainly for
voicemail....) and the E1 span plugged to the 2 servers (with a TE410P
in each server).

- 2 servers configures with Heartbeat + DRBD with the E1 span hooked to
an ISDN guard connected to the main server and the backup one.

Here comes the real question.

Is it "technically" good to connect an E1 span to 2 cards at the same
time (with only one accepting the calls).

Since it is possible with BRI cards, i'm wondering if it could be done
with PRI.

Thanks

Laurent
