Over the last few weeks we have had a recurring issue with calls.
Inbound calls > sometimes users have to redial to get through. Just get a call failed.
Outbound calls > sometimes just a dead line or comes up call failed. but if you redial it works. (no response i believe my phone says)
This also affects things like call pickup.
This also affects internal calls.
We have made no modifications recently. only updated vitalpbx twice (v3)
any insights or what we can do to troubleshoot etc?
usually i would look at the voip provider, but this is happening with internal calls also, for instance internal calls and call pickups.
I am not sure where to start so im about to open a ticket
