Backup configurations, the ability to remotely configure through the Digium technical support (raising the VPN), statistics collection, firewall - all this as a matter of course.

What are the uses for this gateway?

1. You can give a second chance to your old Panasonic or Avaya, who from birth did not know what SIP is.



2. Recently, quite often the IP-PBX goes into the cloud, where there is no possibility to insert a PCI or PCI-E board that we are used to.

Or, if the reception of the stream E1 and PBX are physically located far from each other. This gateway is just a must-have!



3. Finally, the last option. If you want to manage E1 flows, send a part of the DID to your old PBX, and the rest to the new Asterisk / Switchvox / etc server.

All this can be done with this product.
