New features in 5.5.47
|23822||The new pqs configuration field lets you limit the number of queued PTT requests. Previously, the length of the queue had no limit. This is still the case by default, and it corresponds to pqs = 0. To specify a limit for the queue, set the value to 1 or more, as necessary.
With a PTT request queue of 2 or more, PTT clients can get in line while a user (for example, a dispatcher) is still talking, which is not always desirable. However, if you set it to 1, this means no one else can join the queue while a user is talking in the channel and they have to wait until the user has finished talking to take the floor.
