The idea is that you set up the providers in Voxalot and NOT in your Gigaset. Then you register Voxalot in your Gigaset. This lets you do the following:
Outbound calls.
By using the methods I described in my earlier post you can select which provider you need for the call.
Inbound calls.
Depending on the level of premium service that you have with Voxalot you can register various providers. When a caller dials one of these your Gigaset will ring.
Bear in mind that you might not necessarily need to register a provider in Voxalot to achieve this incoming call scenario. If a provider allows you to redirect a call to a SIP URI, then do so, to
xxxxxx@voxalot.com. Incoming calls to that number will ring your Gigaset without your needing to register it in Voxalot.
Remember too that many providers do not need to be
registered in Voxalot to permit outbound calls. Enter the details in Voxalot but set the "SIP Register" field to "No". You should still be able to use it to make outgoing calls.
