[VoiceOps] Maximum latency

[Carlos Alvarez]

Those are some excellent points, Ivan.  They do indeed transfer calls
regularly between agents in various US cities, so I assume the foreign ones
will also.  I'll have to ask.

The US agents are on MPLS to us, 2-3ms at most.

Also, my satellite phone seems to have around 700ms delay, which is quite
challenging.  I should try synthesizing 250ms for them and let them try
it.  Not sure how, but assume there's some open source out there to do it.
