We use Voiptalk / Telappliant. They worked out the cheapest, and work 
well most of the time, but I'm not sure if we shouldn't have gone with

We've about 5 Grandstream GXP2000's which work well. I've just had to 
RMA some Snom M9 DECT phones, as they have problems, but I'm 
expecting/hoping the replacements are better.

They don't with our softphones - Counterpath's Eyebeam. I think you 
might hear the tones if you used in band transfer/dialling, but the TXFR 
button on the softphone takes care of this, and puts the user on hold 
while you transfer them too
