EFR enhanced full rate used to be discussed about nokia phones, turning it on and off etc.
These days do the phones still offer EFR, which is suppose to have better call quality?
Are they on out of the box?
EFR on N95 8GB?
Pretty much all phones manufacturered from around late 90s undoubtably support EFR.
It was more also a Network Feature as well as just a phone feature. It was always supported from the outset on T-Mobile and Orange. I would strongly suspect that its pretty standard on all of them now they have gone 3G. Most nokia phones support Adaptive Multi-Rate in both GSM and 3G mode which has 8 different modes of HR/FR which different compression bitrates and will changeover based on what the operator supports.
As a reference

Supported speech codecs in WCDMA: AMR, and in GSM: FR AMR/HR AMR/EFR/FR/HR
So by the looks of it the phone supports full Adaptive Multirate which includes EFR as its highest rate in 3G and fixed HR/FR/EFR as well adaptive in 2G.
is it easy to tell when EFR is on or not with the sound quality i mean?
i presume it is all automtic on the phone nowadays and yu dont switch it on or off

Nope its been AMR for a while now. I think it was pretty much automatic even back on my old 3210. You could force a particular rate ( if you stuck it in Half Rate you knew! ) but activating EFR on an operator that didn't support it had no effect as it just dialled out at FR.
