When we test the skype without Palo Alto it works fine.What can be the reason? why Palo Alto dont pass the voice outside
There are quite a few things that could be going on via policy depending on if you self-host or use a hosted cloud enviroment, or simply use the consumer version of Skype. I would recommend setting up a isolated test enviroment and turning logging on the interzone-default rule to see what exactly is getting denied and work from there.
Then you would likely be hitting the default deny rule. Without knowning what your security policies actually look like, I would recommend you simply log the default deny rule temporarly and test and see what's getting denied.
