Merge changes from team/russell/smdi-msg-searching
This commit adds some new features to the SMDI_MSG_RETRIEVE() dialplan function. Previously, this function only allowed searching by the forwarding station. I have added some options to allow you to also search for messages in the queue by the message desk terminal ID, as well as the message desk number. This originally came up as a suggestion on the asterisk-dev mailing list. git-svn-id: http://svn.digium.com/svn/asterisk/trunk@115021 f38db490-d61c-443f-a65b-d21fe96a405b

|

* 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.
