Vladimir Yordanov commented on ASTERISK-25302:
----------------------------------------------

Hello,
We would like to add some additional information to our case. We are using Asterisk to make call campaigns for our clients and we are trying to run thousands of calls using 150 lines. The problem is that Asterisk goes into a kind of crashed mode very often and while in this mode calls are still initiated but no messages are played.
We also tried several version of Asterisk and all were unstable. Curently we are using 13.4 as it has best call quality and AMD but is also very unstable and upredictble in terms of when and why it crashes.

> 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?
