I have been configuring a production IP PBX (elastix 2.2.0, asterisk 1.8) and the main stations will be SPA504G's (7.5.2b) and SPA303's (7.5.2b). On both models when in active call, the second incoming call is as if it doesn't exist, and the second caller gets a busy signal.
For testing I use a third Siemens IP phone in which CW works ok: there is a notifying sound and the display shows the 2nd incoming caller ID. For that reason I have excluded the Elastix Server possible fault.
Both SPA devices have Call Waiting enabled, and I just can't seem to understand why is this happening. Do I have to register EXT2 with the same account to get CW work? Or something else?
