I have an Obi202 with two VOIP lines connected in my house. However, I'd like to be able to call between them (use it as an in-house intercom) w/o using the VOIP service, since the VOIP service charges a per minute fee. Can you do that, and if so, how? I assume you can use the ObiTalk Network to call for free, but since both phone lines come out of the same Obi202 device, I thought maybe there was a simpler way?
Thanks in advance for your help.
