Changing Your Voice Profile
If your voice gateway is an ATM standards-based gateway, the voice profile must match the configuration of the
voice gateway. (You do not set a voice profile for the other supported gateways.)
The voice profile determines the following attributes:
¥ Voice compression: ADPCM32 or PCM or PCM only?
¥ Silence suppression supported: yes or no?
¥ Voice cell payload size: 44 bytes or 40 bytes?
You can display and change your active voice profile. To display the current voice profile, enter this command:
voice profile
To change your active voice profile, specify the profile number on the voice profile command.
voice profile <profile>
Silence Payload
profile ADPCM32? Suppression? Size?
7 Yes Yes 44 bytes
8 No Yes 44 bytes
9 No No 44 bytes
10 Yes No 44 bytes
11 Yes No 40 bytes
12 Yes Yes 40 bytes
For example, the following command selects voice profile 7:
# voice profile 7
The active profile has been changed
