Chris, My experience has been that the APX and TNT products require a single SIP proxy, how are you load balancing 2500 calls? If all of the traffic is outbound it is fine, but what about origination? Are you using something other than asterisk as a SIP proxy? On a smaller scale the TNT is a good bet since the number of calls it will do (672 with t3) is closer to what an asterisk box can do without trans-coding. You can connect 1 partially populated TNT to one * box and not need another sip proxy, you can also have a failover sip proxy configured but not active unless the primary fails to respond. Both the TNT and APX have issues with calling name delivery over PRI when connected to a Lucent 5ESS configured to do end office LIDB dips, so calling party name on inbound calls can be a bear, look to connect to a Nortel DMS if you have the option -- go figure the LUCENT media gateways work better with Nortel class 5's than then they do with lucent class 5's. Have you learned something I have not about how to get all of the calls a TNT/APX can handle terminated on the SIP side without still having a single point of failure in the SIP proxy? _______________________________________________ --Bandwidth and Colocation sponsored by Easynews.com -- 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
