So it sounds like you press transfer to transfer a call and don't get dial-tone in order to dial the destination number.  Is that correct?

If so, what model phone and are you using CME or CUCM?  It sounds like maybe an issue with the max number of calls setting on the line.  If CME, it might be due to using single lines rather than dual-lines.
