Description (partial)

Symptom:
Jabber for Android can disconnect from services including Contact Search and Phone Services due to access token expired.
This is happening when Jabber client is missing to setup access token refresh timer while working in the background

When Jabber will send REGISTER message to Expressway, it will receive 407 Proxy Authentication Required and will fail to respond to it. You will see following lines in jabber.log:

[c/services/impl/CredentialsImpl.cpp(416)] [CredentialsImpl] [getSecureOAuthTokenWaitMode] - Get blank OAuth Token, verified:1, expiry time:<unix timestamp>

[nyservice/CredentialsHelperImpl.cpp(188)] [jcf.tel.credentials] [getSipToken] - Failed to get Oauth token
[onewrapper/ccapi_plat_api_impl.cpp(2000)] [csf.ecc.sipcc] [platDecryptString] - Failed to get password
[cc/core/sipstack/ccsip_messaging.c(5397)] [csf.sip-call-control] [sipSPIGenerateAuthorizationResponse] - sipSPIGenerateAuthorizationResponse: decrypted_password is NULL, just return.
