Most of our users want voice.
WB-AMR is THE good thing for them, it makes a difference.
For 90% of our users: those who do not care about HSPA+.
Anyhow (AFAIK), so far only O2 in Moldova and England is using it,
and it is on 3G only.
So users making handover to GSM (and every 10th call starting in UTRAN ends on GSM)
will notice sudden degradation - and forget voice was good before.
It has to be on both systems, so complete voice call between two WB-AMR terminals
has same quality.
Terminal vendors do not support WB-AMR: if they support, then it is blocked in the SW.
Infrastructure vendors claim to support it: but they do not tell us why it is not yet
implemented in real networks.
Is it yet another chicken/egg story? Is there something wrong with specs?
Are there problems with legacy terminals?
Are vendors too greedy to overcharge, so nobody wants to buy?
Will it ever happen in CS domain: or we just wait for VoIP/LTEa?
I want High Definition Voice at home and in roaming. When?
