I have a customer with two sites.
The main site will have the UC500 ... in the remote site they are having two IP handsets, which is easy enough.
At the remote site the customer has two PSTN lines.
Can we use an ATA with FXO or a small gateway to connect these back to the UC500?
If so what is the configuration for this?
What type of ATA or gateway should we use?
We do not have a supported (TAC) deployment model that covers this situation. You may want to look into the recently announced SPA8800, and try to use the configuration guidelines that we posted for the SPA8000. You will still need a VPN between the two sites, of course.
