I need to put together a SOP for testing digital, analog and isdn lines once installed and programed.Basically a standard procedure to make sure it is programed correctly and the line works as it is suppose to. To include outgoing,incoming, internal, Special dial codes and dsn. Don't want to miss anything so i was wondering if anyone has A SOP put together for testing the PHone and lines. This is for a 81c mostly but could include other switches. either way the procedure should be the same. Thanks in advance..
