Hi, I have setup two voip phones (Cisco SPA504G) with Server endpoints, and this works correctly when making and receiving GSM calls. However, when there is no GSM port available, I would like to route to hosted PBX. I created a client endpoint for the hosted PBX on the gateway (which is registered), but when I dial out from phone I get unauthorized. I specifically created an outbound rule for testing from one of the phones to use the hosted PBX instead of the GSM port.
Any ideas?
