[cisco-voip] Drop call for 911?

Tue Dec 16 10:53:56 EST 2008

This won’t drop the calls, but it will let you reserve a channel or two for them.  It is going to require an H323 gateway.

There's actually a parameter that will bump down an executive override to the next lowest level, allowing future executive override calls to bump a previous bumper. oh the fun.

forgive my terminology here, i worked on the feature but resisted the dictionary.

i believe MLPP can only preempt a lower priority call. the first 4 911 calls will go with the same priority level.  the 5th call has the same priority level as the previous 4.  5th call will not preempt the previous 4 calls of the same level.

if you're saying that calls 1-4 are 'normal' calls with lower priority then the 5th call can route via 911 translation pattern, increase priority, and preemtp the first calls.  you can setup locations CAC to get the gateway only allowing 4 calls. MLPP will interact with CAC to drop the existing call.

All that said enabling MLPP changes lots of native CUCM behavior such as forwarding intercepts. this may be an overkill.

I only say that because I have not heard of anyone successfully using MLPP for 911, and without MLPP there is only one way to ensure a 911 call goes out.

CAMA is old school… but they work and do their job without much work at all.

Don’t rule out a CAMA trunk

	H323 is supported?  with FXO?

	It seems Like FXO on a MGCP VGW may not be supported.

	I've never configured it personally but it does show that H.323 gateways are supported for MLPP.   

	You'd definitely have to do some testing.

	I know a couple of people that have tried to use MLPP for this app.

	If you look at the specs, there are specific requirements for use of MLPP.

	Analog lines don't fit into that spec.
