Description

Some providers are not so flexible with the MC VoIP authorization management. It is possible that there are some providers which use for the "realm" not their domain name. 

Solution

The authorization is now more flexible on the MC VoiP side.  Now MC VoIP will always use the same "realm" name as it is used by the provider in the authentication "challenge" SIP request, so that the authentication will always work independend from the "realm".
