* Added two new dialplan functions from libspeex for audio gain control and
denoise, AGC() and DENOISE(). Both functions can be applied to the tx and
rx directions of a channel from the dialplan.
+ * The SMDI_MSG_RETRIEVE function now has the ability to search for SMDI messages
+ based on other parameters. The default is still to search based on the
+ forwarding station ID. However, there are new options that allow you to search
+ based on the message desk terminal ID, or the message desk number.
