Hello,
I have a problem with the battery of my landline telephone. I use it to take part in a Cisco telephone conference that is only for audio. I call a telephone number and a code and then I'm in. My problem is the battery of my landline telephone. It is empty after max. 30 minutes. Normally I can use it for phonecalls of 2 hours. Only in telephone conference the battery is empty after a short time.
Can somebody help me?
