find out the ports needed by your application.

easiest is to check the logs and then open the ports accordingly.

one way to verify the required protocol/port is to configure "capture".

e.g.

access-list ipphone permit ip any

capture ipphone access-list ipphone interface inside

then do "sh capture ipphone" to view all the traffic originated from the ip phone application host.
