Thanks for the information. In an earlier post You told us, that the
local phones talk to asterisk on eth1 using 192.168.101.0 network. Could
You please double check, that the phone did not try to register on
another IP? The asterisk is IIRC on a dual homed machine. Is Your phone
using a DNS lookup to find the asterisk? To which address is that lookup
resolved?
Another hint: Is Your SNOM using some sort of STUN to lookup an public
address? (Just to eliminate some things).

HTH,
Karsten
