I would like to know if there is any way of configuring the Quintum Tenor AS series analog gateways to failover to the PSTN if the SIP gateway is unreachable (i.e. IP connectivity is lost).
If so, please point to appropriate configuration flags/options.
If you are originating the call from the FXS of the tenor, you just need to set passthru to Yes on both lcrg and tcrg to allow the fail over while call is connecting.
