Got SIP response 480 "Temporarily Unavailable". Possible reasons and solutions:

1. Call is rejected by provider/end device. In this case please check with provider.

2. Call fails with HGC 20 due unreachable/unregistered device/provider. In this case check device/provider registration status.

3. Call is rejected by MOR due high load. In this case there will be no CDR in last calls section. More information how to check and solve such issue is available here
