Abstract
A method is provided for the use of a signaling protocol stack by telephony applications which run on different system software images. When a telecommunications session is conducted by a first telephony application, the first telephony application typically controls the state of the telecommunications session through a signaling protocol stack executing on the same system software image as the first telephony application. When control over the telecommunications session is passed from the first telephony application to a second telephony application, the second telephony applications begins controlling the state of the telecommunications session through the same signaling protocol stack by using remote procedure calls.
