We to use our 7935/7936 with trunk ports and move them around from place
to place. No problem at all.

	Odd.  (Of course, I haven't read the documentation...)  On our
2900 and 3500 
	switches we configure the switchports as trunks, specifying the
voice and 
	native VLANs; on the 3750s we identify the voice VLAN and an
access VLAN for 
	the non-voice stuff.  7935, 7936 and 7910 (all without switches)
work fine 
	on both.  As I understood it, the phone identifies itself as
such (via CDP) 
	at startup, and the switch associates it with the voice VLAN.
I'll read the 
	docs and sniff these on startup when I get a spare moment
(hah!).
