[cisco-voip] Guarantee 911 Calls?

[Jonathan Charles]

Yes and no.

See the SRND for CCM4.2 page 10-53, which says that if use MLPP for 911, you
can inadvertently kill emergency calls already in progress (but not
recognized as such by CCM) if you use MLPP with 911.

I would just dedicate one (or more) ports to 911 exclusively.
