The are often issues with DTMF depending on what system you've called into, it would be really helpful for a user to be able to toggle between INBAND and RFC2833 etc. either using a dialing code or using a menu option (that didn't require an admin login)...

Thanks, TJ

Phone access level can be customized by administrator. If the option is necessary it can be made accessible to user login.
