I am looking softphone which has functionality of protected settings from user.
If Admin configure softphone for user, say autoanswer active.
Admin put some protection for that configuration/settings.
When user uses that softphone, he or she can not change any small configuration or settings. means he or she can not de-active auto-answer functionality by any condition.
1. Is this type of softphone available in market?
2. Free (just free to use or open source) or paid?
