Testing PTT on the TC70 and TC75.  I can get voice working over a Cisco AP with no security but can't get voice to pass over a zebra AP with WPA2 and a passphrase.  Both units work, I can get to the internet with both units but can't get PTT voice to pass.

Hi Kenneth,
 
In order for PTT Express to work, you have to make sure network environment is properly configured.
 
There are two major network rules PTT Express follows:
 

Single Subnet rule. PTT Express does not work across multiple subnets.
IGMP snooping must be disabled. PTT Express does not work if network has IGMP snooping enabled.

  
The basic problem you have when you connect to general network like Zebra M-Guest or other is where both of those rules are violated or ignored.
