[App_rpt-users] Avoid squelch noise after receiving a signal

[Shane Morris]

So, you're saying the tail is still there, but you don't hear it because
Asterisk stops transmitting the CTCSS tone just before the tail starts,
meaning the receiving radios actually "don't" hear it?

Interesting way of looking at the issue, thats for sure...!
