.UMA file

Caller Applications Editor will choose to save applications is *.UMA.

internal format will always be the same.

Access Control List
A list of people in a voice mail domain who have access to Modular
Messaging software applications and tools.
Access Number
The number you dial to get into your Modular Messaging software system.
Adaptive Differential Pulse Code Modulation (ADPCM)
A speech encoding method that produces a digital signal with a lower bit
rate than standard pulse code modulation (PCM). ADPCM calculates the
difference between two consecutive speech samples in standard
PCM-coded telecom voice signals. The ADPCM encoding rate is 32 kilobit
per second.
Audio Encoding Formats
These formats determine the way in which audio is recorded on every
MAS in the voice mail domain. This, in turn, determines the format of voice
messages sent using the TUI and desktop clients. Avaya Modular
Messaging supports these formats: GSM 6.10, G.711 µ-law (mu-law) and
G.711 A-law.
You should ensure that the form of G.711 encoding matches that of the
switch. In general, µ-law (mu-law) is used in North America and Japan,
and A-law is used in Europe. If your choice of encoding scheme does not
match the switch, then audio will sound garbled.
