It helps a great deal if you do not cut-and-paste log entries into
e-mail, but rather save them into text files and attach them to e-mail.
Generally, cut-and-paste damages the format of log entries greatly and
makes them much harder to work with.
In your case, as Stephen Miller pointed out, you're receiving a 420
response from sipX. 420 means that the request contained a Requires or
Proxy-Requires header demanding that the recipient support a particular
extension, but that the recipient did not support that extension. (For
details of this process, search for "Requires" in RFC 3261.)
In your case, the log shows this request:

You can see the line "Proxy-Require: 100". Unfortunately, there is no
defined extension named "100". It's possible that the phone is
demanding to use the extension "100rel" (see RFC 3262), but that must be
mentioned in a Require header, not a Proxy-Require header. See the
valid list of "option-tags" (as they are called) at
http://www.iana.org/assignments/sip-parameters (search for the header
"Registry Name: Option Tags").
And in any case, a phone would rarely want to use Require, but would
rather use Supported, as that allows the call to be accepted by a device
that does not support the extension in question.
You should talk to Grandstream support and ask why the phone includes
the demand that the phone support an extension which does not exist.
Also check to see that the firmware on the phone is up-to-date, as they
may have corrected this problem already.
