Sounds like you want the MIS guy to control this remotely. The station he is calling from would have to have a COS with console permissions. This changes the way the phone with the new COS handles features now. When he dials the feature access code for call forwarding he will now get back dialtone, instead of the confirmation tone. He will now dial the extension number he wishes to forward followed by the extension he wishes to forward to.
IE He is sitting at extension 100. He wishes to forward extension 200 (his own extension). The COS on the phone he is dialing FROM has console permissions. The feature access code for call forward/all is *2. He would dial *2, he would then hear dialtone, he would then dial 200 (he wants to forward his phone), and then dial the number he wants to forward to. Say extension 300. So he would then dial 300.
*2200300
*2{extension you wish to forward}{forward to number}
This is a big help if you are supporting users and they have forwarded their phones and don't know how to un-forward them. You can remove the call forwarding for them from any phones that has the correct COS. I would be cautious as to how many phones have this permission. The fewer the better. If not it will cause you more trouble than good.
Hope this helps
