ARDEN is not deterministic, and voip will be a crap shoot on it. Dedicated
links with QoS are needed.

There is no requirement to have your nodes talk to AllStar Link.  Asterisk and
app_rpt are completely independent for private nodes (beginning with 1xxxx).
The HUB could be a public node if you wanted too.

You can do a permanent link where if the system goes down it will try to
reconnect.  You can setup a script to try reconnecting too if you want.

It will connect to the hub, and then bridge to the other nodes.

Most people use SIP.  There are SIP interfaces to LTE/GSM which would work.
