Thanks Alejandro, Currently my Application server is running on DELL PowerEdge 6400 (with 4 Xeon 700MHz processors and 4 GB ram). Likewise Kannel is working on a 2GB Ram Machine with P4. Hopefully it will all work fine in production as your advice also matches the same.
My concern right now is - I am going to get bandwidth from ISP; how much should I get (128kpbs? 256kbps? 512kpbs? or 1mbps?) so that my servers can easily communicate with two operator's smsc operating at a max speed of 200sms/sec? I need an experienced advice as I dont want to stuck in bottlenecks @ ISP speed side coz all others are planned well already withthe help of opinions of experts like you.
