I suppose you know about the upcoming DS3000P <http://www.digium.com/index.php?menu=news/ds3000p> Supposedly it can handle 28 T1's, so I assume the DSP is done onboard.
Maybe you should give Digium a call. P.S. Sorry for not threading, but I get the digest and have not figured out how to inject the original message-id header. > From: [EMAIL PROTECTED] on behalf of Matt Roth > Sent: Wed 4/20/2005 1:10 PM > To: Asterisk Users Mailing List - Non-Commercial Discussion > Subject: [Asterisk-Users] Large Asterisk Setup (~500 Concurrent Calls > +Scalability) > > > > List Members, > > I am involved in the process of designing a large Asterisk setup for a > call center.

The Asterisk master server will provide us with a centralized > point for queuing, digital recording, and music on hold, as well as > configuration, monitoring, and reporting. Configuration of the Asterisk > slave servers would be limited to setting up extensions to terminate the > incoming T1s and setting up IAX2 trunks to the Asterisk master server. > These configurations would be rare, so the slave servers would be > configured manually on the boxes themselves. _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
