asterisk users - Jun 2010 - Silence suppression and internal timing

Is it possible to disable silence suppression by adding silenceSupp:off
to the SDP Asterisk transmits even when Asterisk is using internal
timing? As far as I can tell Asterisk stops sending silenceSupp:off when
internal timing is on, which does make sense, but I would like to avoice
silenceSupp for debugging purposes.

The Asterisk version is 1.6.0.26 in case this matters.
