good idea.  It could also be a global config setting somewhere of whatever 
suffix
is added after the .imsi/.msisdn, defaulting to the osmocom example.

Will you create them accordingly?  As indicated, I think it's [at least] two 
differen
levels;
a) ensuring that keepalive on either TCP or IPA is enabled and works, and
b) creating situations where the same peer establishes a second new connection
   while the old one is still not torn down (timeout not expired yet, FIN 
packets
   lost, ...)
