aa50 intermittant disconnect

We have a strange problem with one of our appliances, intermittently all users will receive a busy signal and then be disconnected when this occurs it will affect four digit dialing through the cloud and POTS line dialing through the Multitech gateway.
We have replaced all equipment except the Asterisk PBX.
Anyone have any suggestions?

I have set up another PBX with all the configs form this office - is there a way to move en mass all the VM files to the new system so that the users do not need to recreate their VM boxes and keep any VM messages they have?
Is there a tool like Filezilla or winscp that will work with the appliance? TFTP will require recreating directories an moving files one at a time - tedious and error prone

rsync ?

Thanks for your response, I believe rsync requires a client on the AA50 which I do not know if it possible to install on an AA50

Here is a verbose capture of a failed call mentioned in my first post:

the gateway circuits are not busy…

Any input/suggestions appreciated.
