Panasonic IP phones
We have recently expanded our company into a neighboring building. Internet connectivity between buildings is active and we're almost 95% sure that our internet connection is not losing it's connection (TWC is currently monitoring but do not worry about this aspect).
We installed a new KX-TDA0470 on our existing system and had it configured. Our PBX card is in building 1 and our IP phones are in building 2. Our Cisco POE switch is connected to the phones through a patch panel and then into the LAN port on the phone. The IP phone model is KX-NT321.
Every morning we come into work, the phones in building 2 are online but there is no dial tone. After disconnecting the phone from the LAN and reconnecting, the phone regains it's dial tone.
Aside from the possible connection dropping, my question is what kind of other troubleshooting can be done to correct this issue? Is it possible that the phones are going into some sleep mode? Does the switch need to be configured to not let the phones go into sleep mode?
Any additional information is extremely helpful. Thanks.

Is that code for the PBX? I'm a little confused.
sorry posted on the wrong question.
What is the dhcp lease?
does it expire overnight so the phone has no ip in the morning.
Does the phone allow a pc to connect in the morning through the built in switch?

The phones are on a static IP address assignment. There shouldn't be a dhcp lease. I'm not sure if it is "expiring" over night because they should keep their assigned IP address. That is why I was concerned about some kind of "sleep" setting. Maybe the switch has a port sleep mode?
The phone does allow the PC to connect. There is a LAN port and then a PC port on the back on the device.

how is the static ip assigned?
If you ping the ip address of the phone does show the device is on/ wake the device up?

You program each device (phone) manually. So I entered in the IP settings directly to the phone.
I can let you know about the pinging of the phone tomorrow morning. I'm sure the issue will still be there.

Important Information
When using a KX-NT321 IP-PT, keep the following conditions in
mind.
• If the unit does not operate properly, disconnect the unit from the
Ethernet cable and then connect again.
It looks like we need a workaround...

So first thing this morning, I walked next door. The phones were online without their dial tone.
Deepdraw - I tried pinging one of the offline phones at their assigned ping. It timed out. Less than three seconds after that, I tried again using the ping xxx.xxx.xxx.xxx -t command. The pings all replied. So it seems as if a ping will "wake" up the device.

Thats great.
Now do you know how to create a script to ping the phones.
I am guessing you could just use a batch file but i could write a few lines of vbs to read a list of ip adresses
or there might already be something like this on the internet.
Also do you know how to add a scheduled task (from control panel)
so you can ping all the phones in the morning at 8:30 so they are ready for 9 am.

The scheduled task guide might help. I can write the scripts no problem. Thanks Greg.

this shows you how to run commands and also how to remove them
I would think you need something like this.
at 8:30 /every:M,T,W,Th,F backup cmd /c c:\scripts\pingphone.vbs

This morning the script ran fine. The IP address all came back with ping replies. Problem is that the phones still had no dial tone. I'm going to double check it again tomorrow to verify.
