announcement port limitation

Avaya PBX announcement port’s maximum capacity is thirty simultaneous connections.

In my vector, I have music for 30 seconds, followed by an announcement and then loop. Does it mean that when I have 90 calls simultaneously entering my vdn I will get 60 calls “ringing” while waiting for announcement port to open up? Is there a way to alleviate this problem without an upgrade?

music isnt provided through the announcement board only actual voice announcements.
