we're having a problem concerning the dial-up connection for our PABX which is a G3si, the modem is not answering to be use for remote maintenance. We only use terranova for dialing to the PABX. We check the lines and it working fine, the vendor suggest to replace the processor but to costly. Do you have any idea what causes the problem or suggest action that can be done to resolve the issue. Their are times that the modem is answering, its like that the port is being locked-out
