[VoiceOps] Time change?

[Leandro Dardini]

Yes, your client is correct. With analogue lines you can send "date and
time" and other information like the Caller ID. There are two types of
messages that can be sent, SDMF and MDMF.

It is better to disable this feature (if possible) or to sync the Adtran to
an NTP sync (if possible)
