Punky,<br> <br>1. Yes, both adapters are supported using the standard 0.52 kernel via the airprime driver, I don't remember if you need to script a modprobe with the usb device ids but either way it didn't require a kernel rebuild.<br>
<br>2. We have to run a custom version of zaptel, so the standard modules would not do the job.<br> <br>3. MPLS will allow us to effectively create multiple VPN-like tunnels across different WAN devices and provide load balancing and failover between the WAN ports. Communications can occur over EvDO, and if the EvDO link fails it can seemlessly transition to the more expensive satellite link without dropping a single packet (although there can be a few retrys). The inbound VPN IP address is the same regardless of this WAN devices are active.<br>
<br>4. We use unionfs to persist changes to everything except parts of var (asterisk needs the /var/spool tree to be preserved for voicemail etc). We keep a couple of separate flash partitions for the delta storage and failover from the primary to secondary on excessive i/o errors on the flash partition. Once the first delta storage partition fails, we move to send second one and let the user know they need to replace the flash card. If the second one fails, we revert to the tmpfs system with no persistent storage.<br>
