[SR-Users] Change in RTP Payload time on the fly

[Ovidiu Sas]

If you have a codec that has silence suppression enabled, then you may
get all kind of arbitrary lengths for packets (as silence suppression
may kick in at any time).
Disable silence suppression on both ends and retest.  If you are still
seeing variable length packets then there might be a problem.
