> After a period of constant work (calls) this problem appears:
> "Oh dear... we couldn't allocate a port for RTP instance ..."
> and Asterisk  stops processing calls.
> The whole port range 10000-20000 appears blocked.
> Only restart of Asterisk frees the ports.
> Any ideas how this coud be resolved?
