Cannot hear myself during calls??

You're not supposed to be able to hear yourself.

That echo is uber annoying

 

Yea beenz is right. I dunno why you would want to hear yourself. Although I do know that some carriers in order to save bandwidth, do not send sound if people are not speaking. It's kind of weird. You can hear background noise when the other person speaks but if they are not speaking there is no background noise and it is completely silent.

 

Some people like the sound of their own voice a little too much

 

Actually, you are supposed to hear yourself - every phone does that, both landline and mobile. It's called sidetone and is done on purpose. you just might not realize it till it's not happening. Without it, people will tend to raise their voices on the phone because they don't hear themselves talking in the earpiece.

Sidetone - Wikipedia, the free encyclopedia

 

Totally agree nwith OP and Eug, sidetone is the norm in fixed and most mobiles, I also agree it lacking on 2.1.

 

Well... I can't wait till 2.2 for my Milestone comes out.
I'm not sure what phone the OP is using, but my Milestone running 2.1 definitely has sidetone. A good way to test is to blow into the mic during a call... you should be able to clearly hear the whooshing noise from the earpiece.

edit: oh... droid eris. Hmm.
