After config and testing near end of a trial the server was updated to 2.4.1. Since the upgrade, the call routing fails periodically. There is dial tone but calls either drop off or get a busy signal. Both call routes show as registered on Voip.MS. A quick survey of various logs showed DNS errors. The server name was replaced with the server IP address and everything was fine until the server was rebooted. Calls were again failing.
This time the server IP was replaced with the server name and all was well again. To see if the problem could be duplicated the server was rebooted and the calls again failed. Oddly, this doesn't always happen on both call routes/DIDs. Sometimes it only affects one.
The server is not the DHCP server, and it is behind NAT. Did not have this issue before upgrading to 2.4.1.

it is hard to say what could be wrong. It sounds as if the provider's domain resolved to several IP addresses and the inbound traffic came time to time from a different address. If it is the case, add all IP addresses to the inbound proxy field. To learn all possible addresses, contact your voip provider or use google to find them.
Otherwise I must ask you to contact our technical support to help you resolve the situation. The information they will need is:
1. Enable debug logs: Asterisk, Asterisk(detailed)
2. Wait for the problem to happen
3. Start packet sniffer
4. Make a test call to demonstrate the issue. If possible, make an inbound and an outbound call.
5. Generate a support info file (link at the bottom of the System Health screen)
6. Email everything back to us.
