Abstract:
In a system having a switching device in a first location, and an extending device in a second location, a method of providing a communications link between (i) a first phone associated with the extending device and (ii) a second phone local to the second location and not associated with the extending device includes analyzing parameters associated with the first phone and the second phone so as to determine that the first phone and the second phone are local to the second location. The method further includes separating signaling data associated with the communications link from voice traffic associated with the communications link. The method further includes directing the signaling data through the switching device via an extension link between the switching device and the extending device, and directing the voice traffic between the first phone and the second phone.
