Losing connection to VOIP provider

[3397premier]

Just about every day our phones go down around the same time - ~9:30AM CST. They are down until I re-register the connection to our VOIP provider. This only affects outgoing calls not incoming.

We get this message first:
Trunk L:10001(VOIP Provider Name) has changed status to unregistered. This means that no more calls will pass via this trunk. Please check your network connection and the voip provider or other SIP PBX

Then we get this one next:
Registration at VOIP Provider has failed. Destination (sip:Voip [email protected]:5060) is not reachable, DNS error resolving FQDN, or service is not available.

The next comes this error:
Device ####### dialed on (AnyLine@Voip Provider) had no available outgoing trunk(s) for Call(from "Username"<sip:[email protected]>;tag=7AC6A33C-E5AFD8EF to #######)

We do not use stun, just a specified IP. Our setup is a Dell R510 server with 3CX Enterprise, Cisco ASA 5505 router, Cisco SG300 switches and our internet is cable with 100 down and 20 up. Any assistance would be much appreciated.

Thank you,

Do you have a system update or backup or anything on that server normally scheduled at the time the line become unregistered?

Who is your service provider? possibly you both have the same provider and that may be why youre experiencing these issues.
