Why can't i talk and listen at same time on my speakerphone

Earphones automatically turn on and the internal speaker turns off when a headphone jack is inserted. There is no way to disable this. Sounds like something is either in the jack or it is damaged. Either way the phone needs repair.

This is a problem with the model of the phone you are using.
It only has a half duplex speakerphone. Meaning it can only do hald the conversation at any given time, either teh listening or the talking.

What system are you using? you may be able to get a different model that would have a full duplex speakerphone, so it could do both.

Press MENU button, scroll to Talk Caller ID by pressing up or down arrow keys, then press Select. Choose off or on by pressing the up or down arrow keys, press Save then press OFF to end

your cell phone probably has an internal speaker for you to hold the phone up to your ear and talk and an external speaker that is used for the ringtone and for you to use the talk on speakerphone option. You can try to use the speakerphone to speakerphone and see if you can hear your callers.
If you phone's internal speaker is not working, the phone needs to be repaired or replaced.

open the phone, clean the surface of the speaker, read the speaker with a meter, if it is working, put it back on and couple the phone but if it does not work replace the speaker with working speaker.

hold down the scroll wheel on the left side while in windows media player, hold it down till a volume bar comes up, make sure that its all the way up by rolling the wheel up

you need a replacement speaker for the phone. if you contact www.fixphonenow.com they should be able to give you a repair quote.

I think the earpiece has become disconnected either in the curly lead or in the handset.
