I have a Samsung OS7200 (s/w 4.30i) with a PRI. What I am trying to do is transfer a call from a SLT to another extension. Basically, answer an outside call on a SLT, press hookflash, dial the extension number where the call is to be transferred to, hang up. I have went through the programming and user manual and cannot figure this out. I must be missing something as this should not be hard. Any help is greatly appreciated. Thanks.
