Hi Cole,
I never tested it but you can try:
Following ports needs to be open
53
80 (normally open anyway for web)
443
4080
5223
udp 16399-16472
++++++++++++++++++++++++++++++++++++++++++
Create a specific custom application for these ports and group them to a custom application set and cofigure security policy to allow these ports.
Verify if it is working.
If it still does not work , then you may need to play with enabling or disabling SIP ALG>
