[cisco-voip] ip phone via a ipsec 3des tunnel

[Michael Thompson]

the default one way delay allowed per the design guide is 150ms,
that's 300 ms RTT.

you'll probably get away with 320 .  Keep in mind, that's 320 in a
good state.  QoS is critical since you have no room to spare.  To be
honest it will be a 'give it a try' approach and see if it's usable.
you SHOULD be OK, but you're pressing your boundaries.

I know, very noncommital, but this is definitely a borderline case.
