Abstract: A capability for online application testing of grown application capacity is presented. The capability for online application testing of grown application capacity enables grown application capacity of a cloud-based application to be tested and validated while the application remains online for handling of live application traffic. The capability for online application testing of grown application capacity enables grown application capacity of a cloud-based application to be tested and validated with minimal impact or risk to the application traffic of the application or the existing application capacity of the application. The capability for online application testing of grown application capacity may support online testing of grown application capacity for various mechanisms for growing application capacity of a cloud-based application (e.g., horizontal growth mechanisms, vertical growth mechanisms, pseudo-vertical growth mechanisms, or the like).

Abstract: A method of processing calls in a telephone switching system which is comprised of voice trunks and a message signalling link for carrying signalling data relating to calls on the voice trunks, and a processor for controlling the switching system. The method comprises the steps of receiving an incoming signalling message on the signalling link, converting the message into signalling messages of a type recognizable by the processor as received from a voice trunk, and including a signalling trunk identification address, looking up in a table a correspondence between the signalling trunk identification address and a voice trunk identification address, passing the messages with the voice trunk identification address replacing the signalling trunk identification address to the processor, and processing the call in the switching system as if the messages had come from the voice trunk.
