One thing that is possible on some other devices is to put a direct SIP address in a speed dial slot or in a dial pattern. For example, on another device, if I put 904@mouselike.org into one of the speed dial slots, then when I hit that speed dial number it will take me directly to a SIP test number in the UK. This doesn't seem to work on the OBi and I have tried a couple of variations (like sip/904@mouselike.org and sip:904@mouselike.org). Is direct SIP dialing not supported by the OBi or am I just doing it wrong?
IP or URL Dialing is not available on the OBI at present. But I can see this as a good candidate for a new feature. The main challenge is to how to fit this kind of dialing pattern into the OBi's flexible call-routing configuration. But having it as a speed dial should be quite feasible.
