VCS Expressway event log errors when Jabber for iPhone and Windows log in

Question

hi folks,
I've deployed Collaboration Edge with VCS Control and Expressway:
my Jabber for iPhone succesfully can log in from Internet and it can IM but not calls and I see next messages in VCS Expressway when Jabber is logging in:
2015-03-27T18:00:28+02:00
tvcs: Event="Authentication Failed" Service="SIP" Src-ip="Client-in-the-Internet-IPaddress" Src-port="49543" Detail="No valid authentication" Protocol="TLS" Method="REGISTER" Level="1" UTCTime="2015-03-27 16:00:28,204"

tvcs: Event="Inbound TLS Negotiation Error" Service="SIP" Src-ip="Client-in-the-Internet-IPaddress" Src-port="49512" Dst-ip="Expressway-IPaddress" Dst-port="5061" Detail="No SSL error available, probably remote disconnect" Protocol="TLS" Level="1" UTCTime="2015-03-27 15:58:08,582"
"Digest User" in the "Protocol Specific Information" section of Phone Configuration selected right user. in this Jabber I see following error "Failed to get device configuration". however Jabber for Windows and for Android hasn't such issues - they succesfully can log in from Internet and it can do calls and IM but I see next messages in VCS Expressway when Jabber is logging in. The same log line appears when Jabber for Android log in:
tvcs: Event="Inbound TLS Negotiation Error" Service="SIP" Src-ip="Client-in-the-Internet-IPaddress" Src-port="56751" Dst-ip="Expressway-IPaddress" Dst-port="5061" Detail="No SSL error available, probably remote disconnect" Protocol="TLS" Level="1" UTCTime="2015-03-27 14:19:11,769"
and I can't find any information which describe such types of error.
thanks!

Thanks Srini, but the instructions have two options:
1. Use the Control Panel, select "Oracle 11g..." and uninstall from there.
This is of course the first thing I tried, but as I said, there is no entry for Oracle 11g in my "Programs and Features" applet.
2. Download the install package and run OracleXE.exe with the remove iss file.
Firstly, there is no OracleXE.exe in the package I downloaded, just setup.exe;
Secondly, setup.exe ignores the iss parameter and tells me that OracleXE is already installed (setup.log contains ResultCode=-3) so it can't be installed.
Is there somewhere else to get an OracleXE.exe that will work for 11g? Or are these the instructions for 10g and haven't been updated yet?
Am I unusual in not having a Control Panel entry?
(and I understand this is a beta - that's partly why I'd like to uninstall it - I'll go back to 10g and not be so impatient :))

Andrew
