Kindly clarify some of my confusions. We have 2 Gateways(AS5350XM) + 2 GateKeepers(Cisco 2811 Routers) & have been added into the Call Manager. Now I have to insert some FXO cards(for PSTN lines) since Gateways are not modular I've inserted these cards in GKs. Now I need to add these GKs as Gateways into the Call Manager so that I can add the Dial Plans accordingly.
Keeping this into consideration that I cannot add same device with a single IP into a call Manager I have binded a secondary IP on these GKs so that these can be added into the Call Manager as GWs. Now is this a right & recommended technique to reuse a GK as GW??
If anyone having a similar setup pls. share & provide reference links as well.
