Types of Toll Free Conference Calling Plans
There are alternative toll free conference calling plans such as stand alone and follow me services which can suit individual needs. Stand alone service allows the user to connect their phone behind PBX equipment while follow me service is useful to those who are constantly on the move. This facility allows you to change your “ring to number” at any time by simply logging on to your account and changing your preferences. This is a very useful and convenient alternative and is especially suited for travelers and salespersons though the call charges may be slightly higher at 6.9 cents per minute. There is also a provision to route your calls to internationals destinations so that your foreign colleagues and friends may contact you as if they were local callers. These then are some of the readily available toll free conference calling plans that one can avail of without having to pay too much.
