I'm a new subscriber to 2Talk VoIP, and have set up a number of lines around our business (a luxury lodge) so that each room has its own phone with a unique phone number that can be used to receive calls during the guest's stay. I would also like to set it up so that guests in one room can dial an extension to dial guests in another room, as well as reach us at the lodge office, etc.
I have two base stations, a Siemens Gigaset C610IP and a Gigaset A501IP. Three phones are paired to the former, and six to the latter. For some reason, I can get the three on the C610IP to "extension dial" each other, but they cannot "extension dial" the phones on the other base station, and the phones on the other base station cannot extension dial at all. Is this an issue with the different base station, or is it a settings issue? Any help would be appreciated!
