Audio 3cx / SBC

[Central Oto - 1Stop]

Location A has 3CX server, Location B has SBC. Twice this week, the phones over at Location A had audio and outbound issues. They could not hear anyone on their end and vice versa, as well as they were not receiving outbound calls. I decided to reboot SBC PC at Location B and everything at Location A fixed. Is there a reason why this is happening? For temporary resolution, I have a scheduled reboot of SBC every morning so that this can lessen the issue arising, but I would like a more permanent way to stop this.

Are the phones at A using the SBC at B?

When the issue happens, does the mobile apps / webclient also have the issue or only the IP phones?

Do the phones at B work?

Not receiving calls also indicates that your sip trunk was not registered.
At that moment you had issue with external calls only?
Are you using a supported provider?
