I am having an issue with our XTL5000 mobiles since we went AES encrypted. Our XTL5000 mobiles have a 1.5 - 2 second delay before they will pass any audio when an encrypted transmission comes through on a p25 repeater. If we go direct simplex p25 encrypted the audio comes through without delay. We have played with the unmute time, modulation, unmute rules and this has not worked and also no difference in firmware from latest to older versions. We have a mix of radios APX,XTS and only the XTL5000 have the issue. Has anyone here had this issue ?
