After migrating from Open Call Media Platform (OCMP) 4.4.1 to 4.4.3 the conference service using Network Announcement (NETANN) conference stopped working.
OCMP answers "503 Service Unavailable" and nmsg file shows:
- Add at least one video codec on OCMP base 4242
- Edit file /opt/OC/share/ocmp/reservation_configurations.xml and set "RESERVATION_OPTIMISM" to "100":3
<value>100</value><description>Performance multiplier (percentage) can be manually set for a more efficient hardware than where calibrated</description></property>
- Restart OCMP Base
Problem will be fixed on OCMP 4.4.3 Reactive Patch 301 specifying audio mode as default.
