Can a working OBI ATA be reached through Sipdroid/PBxes?
Sorry if this is a real ignorant question and/or if the wording is incorrect.
I know that I can make a call to an OBI if I set up a 'classic' extension for it in PBxes, or, just dial the number associated with it through Sipdroid.
Can you set up a SIP extension for an OBI?
Does this even make sense?
The straightforward way is for OBi to register to PBXes, same as registering to a VoIP provider. However, this requires an SPx slot. If you don't have one available, you could reach the OBi via SIP URI (using port forwarding and dynamic DNS if needed), or via e.g. iNum, if one of the providers on the OBi offers an iNum.
The above assumes that you just want to call the phone attached to the OBi, or make calls via the OBi's AA. If you want to access the connected POTS line (OBi110) or VoIP services on the OBi, without two-stage dialing, you can set up the OBi as a sub-PBX, though that does require an SPx slot.
