Windows Server 2008 Filtering Platform Packet blocking connections I want

Working in a test environment with a phone system that uses IIS for end user's portal access to the vmail sever. all phone apps apps work except the ability to play the voice message via the browser. playing message by the phone, yes.

environment
-phone machine is it own box
-voice mail server is on windows server 2008RC2
-user uses a third party web app (Port:8080) on same server

The phone connects though the phone machine connection to the VM server. The user, uses third party web app to interface with the phone system and ia able to control the phone feature like pickup and dial... when the user click play voice mail via web, a message pops up in the browser "not able to from browsers". If the user changes the setting in the web portal to play the message via the phone. the message plays on the phone from the web app.

already done;
-disable firewall vie local policy
-update c++ (fixed errors in event log and cell phone app connection started working)
-turned on audit / security failures

Get entries in the security logs
-The Windows Filtering Platform has blocked a packet:5152
-connection source in error are the different devices trying to connect to the phone system web app.

even with the firewall off, The Windows Filtering Platform has blocked the connection, how can i turn of filtering and tweak it later
