If your requirements are simple and you only have a small number if E1s,
you can also use a Cisco 36xx with a T1/PRI card. 3600's have limited
capacity but we run 4 PRIs on a 3640 no problem and it's been very stable
for several years. The nice thing about 3600's is they are almost free,
although the cards are not.

Dear all,

A quick question on deploying Asterisk over E1. I am looking for a low-cost
solution for bridging my E1 line and Asterisk with reasonable stability
suppoing both voice and fax. Will a Digium T100 be good for that or I
really need a Cisco AS 5400 for this task? What is the difference between
using a Digium card vs a physical gateway server? What other alternatives
are available?

Your suggestions will be greatly appreciated.

Thanks,
Mark

The Cisco's also support T.38 gateway functions whereas Asterisk can
only do pass thru. Either way you'll still need another server,
typically hylafax, to receive the faxes to get them somewhere useful.

In my experience the Cisco switches are definitely the way to go for
the ISDN/SIP gateway and then back it on to Asterisk for any PBX bells
and whistles needed. If you've got more time and patience than money
then a card in Asterisk for the ISDN gateway is an ok solution.

Regards,

Greyman.
