We have recently upgraded asterisk and our linux servers and this has caused a bizarre 1-way audio issue for queue users which we cannot seem to resolve.
We moved from asterisk 11.25.1 to asterisk 14.1.2 and to asterisk 13.8-cert4 with the same negative issue occurring on both installs.
We are currently using Ubuntu 16.04.1, which was upgraded from a prior version.
The issue -----------
We have lost caller-id on at least 50% of our inbound calls. Nothing has changed with our carriers or our trunks. No configuration changes have occurred. The upgrade has, for some reason, restricted caller-id.
