Some follow up on this topic:
When we discussed this internal it showed that this is not as trivial as it seems.

While the customer affected mostly has this issue during break times, a time based limit wouldn't solve this entirely (e.g. for weekends). A bare raise of the number of call assets may have negative effects in terms of performance. Other users with low call traffic may want to keep the number of assets low. Having a caller log for like the last 2 months wouldn't be helpful.

We'll update this issue accordingly if anything moves.

This indirectly has gotten a duplicate of #3550 which did introduce a setting that allows to use up to 300 call entries.
