Speaking of which. SPA3102 does not provide full signalling. For instance what I am really looking for is Ringback signals i.e. for invite it sends ok almost instantly and only then starts to dial number. So, channel is already open and if on callee is busy - I will hear busy tone, but asterisk won't react accordingly. I guess Digium cards or Sangoma do support full signaling, but question is is there any gateways which can do full SIP signalling as well?
