[Asterisk-Users] What's the deal with "secret=" vs. "password="?

[telephony at jonjay.com]

I have RTFM, Googled and experimented on this issue, but it's
still unclear.

In the sip.conf file, what's the difference between:


secret=welcome

    and

password=welcome


The O'Reilly book example uses the first version, but I can't
get no registration with it.  The only way my SIP phones are
registered is by using the second form.
