five SIP+RTP sessions to the same remote host to appear as if they are

running on debian may be registered (through Kamailio) on the same
remote host by using five different accounts and source IP addresses.

Should be simple, but so far cannot find good sources
of reference. I
need your advice.

Snipping your long story, summarized to: sipserver only accepts 1
connection from 1 ipadress (which is kind of strange, have you tried 1
ipaddress and different source ports?) and you want to make multiple
from 1 machine (with multiple ipadresses).
If my understanding is correct the solution is simple, in kamailio use
force_send_socket to send requests to the sipserver from different
adresses (10.1.1.1N).
The hard part is how you will differentiate the REGISTERS from asterisk
to the sipserver. The easiest way I can think of right now is to listen
on multiple ports with kamailio and tell the kamailio peers to connect
to these in a unique way.
So in kamailio it would something like:
if($Rp=="5070")
{
force_send_socket(10.0.1.10:5060);
}
else if($Rp=="5071")
{
force_send_socket(10.0.1.11:5060);
}
else if(...)
