I have a ip office with 9.0 software. Several system wide issues on all extensions and POTS lines which may be related. Intermittantly when dialing externally it appears the call is being processed but then drops while waiting for ring back. Intermittantly when using automated systems(banking/Conf) the numbers are not being recognized by the equipment on the other end and numbers are not appearing on the phone display. Intermittant call drops mid conversation and intermittantly when receiving calls the set will ring but when answered the line has been disconnected. To the caller it appears that they have been hung up on. Any ideas?
