Hi,

I am looking for Session Border Controller to serve about 600 concurrent calls (media flow-through, codec g729, no transcoding, no vad, a lot of number translation, ACL integrated on the same router); I consider two solutions:

1. Cisco 3845

2. Cisco 7200VXR with NPE 2G

I found following info:

http://cisco.com/en/US/products/sw/voicesw/ps5640/products_qanda_item09186a00801da69b.shtml

there is a table that shows 3845 serving 750 calls and 7200 only 500 calls. There is no info about what NPE was used wth 7200.

Do you have any perofrmance experience with SBC at 3845 and 7200VXR? Which soluton would you prefer?

ANother quesion - what is SBC performance for XR12000?

Regards
