This issue is found while verifying issue XECS-149.
When a audio file name with a space in it (say ex: auto attendant.wav) is used for Callpark, ACD, MOH, Paging Groups plays correctly without any issues. Also, for a audio file with a space , orbit.xml file inserts %20 instead of spaces/blanks for Callpark and MOH.

But, when a audio file with a space in it (say ex: auto attendant.wav) is used for AutoAttendant, it fails to play the audio file when AA number is dialed.

Steps to reproduce:
1. Navigate to Features ---> Auto Attendants and click on add Attendant with following details:
Name: s1
Prompt: auto attendant.wav
2. Now, navigate to System --> Dialplans and create a custom Attendant dialplan( say, aa1) to use s1 as Default Attendant with Extension as 666.
3. Click on Apply and then Activate the dialplans.

Expected Result:
When 666 is dialed, the custom attendant auto attendant.wav should be played to the caller.

Actual Result:
The audio played (auto attendant.wav) is not heard by the caller.

Note:
1. AA plays the audio correctly without any issues for a audio withOUT any spaces in it.
2. Snapshot has been taken from HA Master. Issue also exists in a standalone system.
