Hi it sounds like the problem is with either the base unit board or the board on the phone.
Do you have one main phone plugged into phone socket and the other two are extra phones that just plug into mains and pick signal up off the main phone if this is the case then the problem will be with the main base unit.
So first thing i would do is check the cable to the phone from phone socket is secure and hasnt been trapped under furniture or somebody triped over it and damaged the wire.
If this is not the case then the problem will be with the base unti itself and as the waranty has ran out this usually means that the phone was only really supposed to last untill this time this is the same with most electrical unit you buy.
The problem could be something as simple as a bad solder on the main board near where the signal is sent from the base.
I would say that the actuall phone is not to fault because if the main phone was at fault then the other 2 would work fine.
If you are ok at taking electrical units apart and can test the board near the signal output on the base it might just be that the solder has failed after this time.
If the phone works for a short while before it dropps the calls then it more than likely is a solder problem the thing is it is difficult to get a spec sheet for these phones i will look and if find one let you know.
Have you tried plugging a different phone into the phone socket to eliminate a problem at the phone exchange let me know how you get on and ill let you know if i find anythnig for you ok

    Hi have found out their is a common fault with this unit they all get this same problem its a problem that wasnt resolved when they was making these they have a really bad review looks like their is no easy sollution also would cost to much to repair as it more than likely needs a new board.

    The best thing you can do is sell them on auction site for spares as people will need things like battery even people can use the handsets as it is the base that has the fault you should be able to sell them thats the best thing to do with this make and model of unit ok sorry cant offer anymore help but seems like genetic problem sorry

How Long Do I Have To Charge My Vtech 5808 Battery?

Lithium batteries can be charged whenever you want for however you want. It is best to charge the phone overnight. you cannot overcharge the battery, and you do not need to deplete it before recharging it. Older batteries had a problem in which improper charging would damage them, but this kind of battery does not. Best of luck!

My phone keeps saying unable to connect

is your phone about a year old? It may be the battery. The vtech phones have weak batteries that clunk out after about a year and you'll get dropped calls, looking for base etc... The phone still appears to be working and the battery indicator tells you it's charged, but the battery is too weak to keep the wireless connection going.

Had the same problem and replaced the battery. had the cheapest ones. But it's a knockoff, so I don't know how long it will last. So far it's been 3 months and the problems are gone. I would try that first and see how it goes. I paid about $15 including shipping. If you buy it from vtech it's at least double...

handset dies or cuts off frequently during calls or when talk is pressed to answer even when fully charged and right in front of the base unit. Beyond frustrating.
If I hadn't lost the reciept, I'd return this useless phone in an instant.

We are having similar problem with vtech 5808

Install new batteries! Be sure to let them charge fully (overnite) before first use.

I have 5 of the i5808 expansion phones around my house - most about the same age - and they all started acting up ithin a few months of each other. I "experimented" with a new battery for one, and it solved the issue for that one I replaced the batteries in each of the others that were experiencing the problems. This was about 2 to 3 months ago, and all phones have been problem-free since the new battery installs!

Hope this helps.

5808 drops call and starts searching for base

Got a wireless router? Change channels on the router off Ch6, the default channel and that may help your phone communication to the base station. I have had wireless phone customers lose their wifi when their phone rings, same frequency or intereference on that frequency.

This model of phone have serious problem regarding the battery. This phone use a lot of juice out of the battery. I'm pretty sure that when your battery is foul charge it doesn't do it. So the problem is in the handset. When your battery starting to get to low you loose your connection. Why?...Because the detection to LOW_BATT in your handset is not calibrate adequately. So it thinks that the batt is weak, to weak to make a conversation.

The other problem could be that your handset doesn't really foul charge your battery. So when you are to far from the base or talking for to long . There's not enough power in the battery to raise the output signal level(db) to your base.

Stupid Phones

If you have two identical handsets, try swapping the batteries. If the problems moves with the battery, then it is old or weak and not holding a charge. That what it sounds like to me.

Hope this helps, and please rate my answer, good OR bad.

Good luck!
