I currently have a remote analog POTS line that needs to be accessible to our HQ. We would like to be able to take a SIP phone line and have it register to a device that has the analog line connected to the FXO port. The catch is our SIP phones are on a completely different network than where the device will be located so it will be layer 3 connectivity. Can this be done with the Netvanta 6250? If so is there a config guide I can use to get this operational?
As long as the phone network can reach the 6250, then a SIP phone can register to it. The fact that the traffic traverses a router along the way isn't itself a problem.
Gotchas of making this work include NAT between the phone and the 6250 by an external device (try to avoid this if at all possible), configuration and provisioning of the phone itself. If the SIP phone will also connect to another VoIP system, then things get more complicated, including (this isn't an exhaustive list...)
