1. Can I have multiple smsboxes for one number to have a sort of load balancing?
depends. It's not clear from the question for which direction (MT/MO) you want to "provision" one number. Is it for MO? Generally Kannel uses the concept of internal load-balancing via connecting N smsboxes to bearerbox and resolving internal load status via heartbeat messages internally. So generally speaking, yes, you can connect several smsboxes to bearerbox.
2. If I have different smsboxes can I also have different logs for all smsboxes and also different logs for the bearerbox?
yes, each smsbox would have it's own config file and hence an own smsbox group and hence an own log-file defines. Bearerbox has one global log-file but can also seperate the smsc-id specific entries to own log-files, see user's guide.
3. When I can make multiple connections to the Telecom with more then one server, should I also need a hardware device between my adsl and my servers (something like a router with load balancing support)?
grrr, things get complicated when you try to "load-balance" towards telcos. Reason here is the architecture side. You are the client towards the SMSCs. A load-balancing is usually on the server side. So there is no need to load-balance as client. Things get more complicated when it comes to HA issues.
Most of my questions are based on load balancing, I don't even know if I generate enough traffic that I need to start load balancing, because I heard Kannel should be able to handle much more sms/sec, but in real life I haven't been able to do this "yet".
let us know what your expected maximum peak rate sms/sec would be? ;) load-balancing comes into play when you have something more around 400-500 sms/sec. The bottleneck is usually the SMSC connections, not Kannel capacities, except you are VERY VERY close to the SMSCs and they push you really hard.
