Your register uri is email.cz, but you test only for the ip
(10.1.22.237) in your ser.cfg. ser thinks the request is not for it,
resolves email.cz and sends it to 62.168.57.98:5060 which seems to drop
it.

Use if (uri==myself) instead of if(uri~=10\.1 ...) in ser.cfg and add
alias=email.cz at the beginning of the config. You might also want to
add a DNS SRV record for _sip._udp.email.cz pointing at 10.1.22.237 to
your internal DNS server.
