Has anyone tested cordless phones and really got them working with 3CX? I've tried the Snom M9R and it just seams slow when pressing buttons. I've also tried the iPhone app to maybe use iPod touches instead but the whole sleep thing with the delay to wake them up it too long and unreliable. I have been looking into using the Snom M65 but not in the supported phone list and very expensive because it doesn't come with a base which is an extra. I'm looking for fully integrated and supported with 3CX, transfers, shared phonebook etc. Would prefer wifi over Dect but those seam to be not too common.
