ML17929 line in use and clock issues
We just bought ML17929 phones for our office. We have four phones: two that are plugged directly into single jacks that receive both line 1 and 2, and two phones that are split from one single jack that receives both line 1 and 2.
Line in Use Issue
Sometimes the 'line in use' comes on one or two of the phones but not the light and sometimes it's the light and the comment, but usually there's no indication that someone is on the line and we pick up the line to interrupt the conversation.
Clock Issue
Also, for some strange reason the time changes when a call is received, no matter how many times I reset it.
I've looked through the manual but I'm trying to understand if it's an issue with the phones, the cords, the lines, or the phone company. Any ideas?

My first suggestion would be to attempt to simplify your configuration. Can you unplug two phones, make some test calls and see if the problem still exists for the remaining phones. If so, then disconnect one of the two remaining and connect one of the others where it usually sits and see if the problem comes back. Repeat with the fourth phone (disconnecting the third again).
If you discover that a particular phone is causing the issue, swap that phone with another one at the same jack. Does the problem remain with the phone or with that jack.
Did it never happen with 3 phones? Perhaps the four phones draw too much on the line. What kind of two line phone service do you have? POTS? VOIP? something else?

It's voip. And we never had four phones before. We had a base unit at the back of the office and a wireless base at the receptionist desk. We just upgraded to four phones and the phone company came out to upgrade the existing jacks to add the new line 2.
I'll definitely try to unplug the phones and see if that helps.

As for the time... whenever a caller id message reaches the phone from the VOIP ATA, the phone looks at the timestamp in it and sets the clock accordingly. While you can set it manually, it doesn't show anyway to keep it from setting it from the VOIP caller id message. So, you need to talk to your VOIP provider about sending you the correct time stamp in the caller id.

Pretty much what @JefferMC suggested, plus you need to be sure the lines are correct on all phones.

Just now got some time to check the manual for the ML17929. Checking the time and date settings there is no way to turn off the time and date set by caller ID, so your VoIP provider will need to correct that. Also, it's very important that the lines are correct on all phones. The phones communicate with each other by a data link on line one, so you need to make sure line one is really line one on all phones. Don't depend on the line light you need to verify by removing line two and seeing if all phones still have dial tone on line one, you can remove line two at the NID, which would be the most accurate way to do it. Unplugging all but the main phone and plugging in one at a time until the problems starts is also a good way to determine which phone is the cause, as suggested by @JefferMC . I'm betting on at least one phone the actual line is not the same as the others.
