I have to agree, 4xT1 density is too low for $2500. If there is some magic sauce inside the box then maybe.
What exactly is it? A 4 BRI card in a mini Linux install? Who maintains the SIP-ISDN translations? What about docs and support? What are the chances the box is really just an mini * server? > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:asterisk-users- > [EMAIL PROTECTED] On Behalf Of Jonathan k.
