Palo Alto Firewall and Sorenson VP 200 (Video Phones)

[Harry Zahlis <harry.zahlis () FRESNOCITYCOLLEGE EDU>]

Our District just purchased and implemented a new Palo Alto Networks firewall.  We have run across an issue which has 
stumped a lot of people.

Our deaf faculty and students use a device provided by Sorenson (Sorenson ntouch VP-200) for telecommunication.  At 
first we opened the specific ports required by the Sorenson devices but we could not place phone calls.  We opened all 
ports, TCP and UDP in both directions (any-any) and we still cannot get the devices to work properly.  Each of the 
devices has a static address on the inside and outside.

My questions is does anyone have a Palo Alto Networks firewall and utilize Sorenson video phone devices on your campus? 
 I would really be interested to know how you got these suckers to work.

Thanks in advance for any assistance.
