SIP softphone register with CME without username/password

Hi, all,

I set up a SIP-SIP gateway on a C2821, this C2821 routes all outbound
calls from CUCM to an ITSP (both over SIP trunk), C2821 itself does
not act a CME, i.e, there are no SCCP or SIP clients registered to it,
in fact I do not have any configuration that would allow a SCCP/SIP
phone to register/authenticate, however, I found that a software SIP
phone that has IP connectivity to this C2821 can register to it and
therefore make outbound phone calls. I am puzzled, did I miss anything
obvious?

Thanks,
Jian
