Hi Andy,
The CWIC registerPhone function allows unauthenticated registrations by passing "authenticate: false" and "password: ''". Setting the authenticate flag to false basically means "bypass authentication if password is empty". This code registers myuser with device ECPmyuser to CUCM address 1.2.3.4 without authentication:
jQuery('#phone').cwic('registerPhone', { user: 'myuser', password: '', cucm: '1.2.3.4', authenticate: false });
Hope this replies to your question, Thomas

Hello Thomas,
 
We modified the code sample.html from Jabber SDK.
But we got the error message "Unable to login: Login Error eNoLocalIpConfigured".
I don't know how to fix it.
Do you have any idea for error message ?
Thank you!
Andy

        $('#phonecontainer').cwic('registerPhone', {
            user: user,
            //password: password,
password: '',
            cucm: {
                tftp: (cucm || '').split(','),
                ccmcip: (cucm || '').split(',')
            },
mode: phoneMode,
            //authenticate: auth,
authenticate: false,
....

Hi Thomas,
 
You were right. userID with "." for instance return the previous error mentionned by Andy.
I had the same issue and changed for a username with only alphanumeric and it works fine.
 
However it works only for softphone mode. When I select Deskphone and clic on the login button it returns me another error:
Unable to login: No credentials configured eNoCredentialsConfigured
 
Any idea ?
Regards
 
Fabian

Hi Thomas,
The command "ping <cucm>"  and the authenticated regstration with same user is work.
But, The unauthenticated registration is failed.
I has sent the file softphone.log to jabbersdk-support@cisco.com.
Please help.
Thank you!
Andy
