When I am on a call and another call comes in, I do not always want to take the second call, using Flash. Callers tell me that they are not able to leave a voicemail message if I am already on the phone. Is there a remedy for this? I may not want to take a call, but I do want to hear voice messages. Thank you.

I do not know allot about the s5090, but I can give you general information based on how most Nikon pocket cameras are designed to work. If the Nikon is set to one of the automatic modes it is designed to prevent you from taking a picture if it senses that there is insufficient light to get a properly exposed picture. The camera may be telling you to rase the flash because it needs more light. Also, somewhere on your camera there is probably a menu that allows you to choose the flash mode. It may be in your regular menus or, if your camera has a round left-righ-up-down switch on the back, you can select the flash mode by pushing up and then using the right-left keys to choose the flash mode. The mode you select is locked in when you push the button in the center. In general, the modes are automatic (the camera decides when flash is needed), red eye reduction (the flash activates twice; once to cause your subjects eye's iris to close and the second to take the picture), flash always (flashes regardless of the ambient light) and flash off.

First off, make sure you case isn't covering the second microphone used for noise canceling. Second off, tell the person on the other line to turn up their volume.

So what, exactly, is your question? Physically, you order a second line in a "hunt" group, and plug or wire it into the system cabinet. By default, a Nortel system has 2 lines already programmed to the sets, but you will probably need to activate the second line appearance in programming.

Depending what number your extensions start with, you need to go to the programming for the auto attendant and "undefine" the number in the menu. More than likely, it is built as a "thru-dial" and allows callers to punch in the extension. If you remove this, callers will have no other choice but to use the options in the menu. I can walk you through these changes if you want.

Yes it very well could be your phone lines and not the system. Call your provider and tell them you have low speech path on your lines. They will troublshoot it.
