I am new to Freeswitch. I am trying to create a MOH server for our Metaswitch. Currently I have it working, but it will only play on audio file. I would like to set it up to play a particular audio depending on the inbound phone number. The below code is in my dialplan/default.xml and does not work. Could someone tell me what I am doing wrong? Thanks for any help. <extension name="4000_hold_music"> <condition field="effective_caller_id_number" expression="^(1000)$"> <action application="answer"/> <action application="execute_extension" data="is_secure XML features"/> <action application="playback" data="$${hold_music}"/> <anti-action application="set" data="zrtp_secure_media=true"/> <anti-action application="answer"/> <anti-action application="execute_extension" data="is_zrtp_secure XML features"/> <anti-action application="playback" data="/music/music1.wav"/> </condition> <condition field="effective_caller_id_number" expression="^(1005)$"> <action application="answer"/> <action application="execute_extension" data="is_secure XML features"/> <action application="playback" data="$${hold_music}"/> <anti-action application="set" data="zrtp_secure_media=true"/> <anti-action application="answer"/> <anti-action application="execute_extension" data="is_zrtp_secure XML features"/> <anti-action application="playback" data="/music/music4.wav"/> </condition> </extension>
