I see "no samples for gxxx" warning messages on Asterisk CLI

This warning looks like this:

[2011-09-29 15:31:02] WARNING[29885]: translate.c:155 framein: no samples for g723tolin

It means that one of clients, is using silence suppression mechanism which sends audio frames that do not contain any samples. That is causing these Warnings on Asterisk CLI.

These warnings can be ignored.
