Ok, thanks for the info.
I thought it might be possible to send a re-invite to initiate another codec, 
or to re-write the invite on 488 failure, changing the order of the supported 
codecs to put g711 in the first place. 
Frankly I'm surprised the softphones fail at all, as g711 is in the list of 
supported codecs sent by the sipura's invite, just not in the first place...
I'm finding out I still have a lot to learn here though...

Thanks,

Richard
