Summary: UAC parse error

Initial Comment:
When trying to authenticate to voipbuster.com with UAC
I get the following error message:

/usr/sbin/openser[15766]:
ERROR:uac:parse_authenticate_body: parse error in
<Digest
realm="sipdiscount.com",nonce="227614094",algorithm=MD5>
around 59

The SIP packet which is sent by voipbuster looks like
the following:

SIP/2.0 401 Unauthorized..Via: SIP/2.0/UDP

look like the problem is the algorithm value which is not
quoted. The parser expects a quoted value even if the
RFC2617 does not enforce it.

  algorithm     = "algorithm" "=" ( "MD5" | "MD5-sess" |
                  token )

I will take care and fix it.
thanks for report
