OK. Partially solved my own issue by doing the following:
tep 1 On the Cisco Unity server, browse to the directory CommServer\Cscoserv\Ciscopca\WEB-INF.
Step 2 Use a text editor to open the web.xml file.
Step 3 Find unityurl and verify that the value enclosed by "" and "" is a valid IP address or DNS name for the Cisco Unity server that is hosting the AvXml web service/portal.
The value cannot be either of the following:
* 127.0.0.1
* "localhost"
Step 4 Close the web.xml file.
However, When I hit the playbutton to play over the phone I get the old unknown problems... message. any thoughts
