You are helping a new Sales Engineer learn about Avaya Aura survivability. If a branch that has only SIP devices and has deployed a Survivable Remote Communication Manager and Session Manager, the engineer wants to know what happens when the connection to the Avaya Aura core is down.
What are two things you would tell the engineer? (Choose two.)

You are working on a proposal for a location with the following requirements:
* 275 H.323 stations
* 125 analog stations
* 8 voice mail channels/ports needed
* G7.ll should be used for station to station calls
* T1s needed in 6 stations per trunk sizing
Which statement describes how to calculate the number of T1cards required?

You are planning a branch location that requires Tl/El Public Switched Telephone Network (PSTN) trunks.
There will be a peak hour usage of 1 PSTN trunk for every 20 of the 500 users.
How many PSTN trunks and DSP resources will be needed to support calls between IP telephones and the PSTN in the branch?

Which change was made to EC500, to provide CS1000 Mobile-X like feature experience?

The adoption of Avaya Aura(g) Media Server by Communications Manager (AAMS-CM) provides many of the resource capabilities of the H.323 Media Gateways (MG); but it is not always a direct replacement. With Avaya Aura and Communications Manager (CM) 8.1, both AAMS-CM and MGs are sold as media resource options, since AAMS-CM can support more channels per instance than either H.323 media gateway.
When would AAMS-CM be deployed, instead of a media gateway?
