A private branch exchange (PBX) or other communication system switch is configured to establish connections for at least first and second calls associated with an external endpoint, using respective first and second trunks. Upon detection of a voice path connection between the first and second calls in a network external to the switch, the switch conferences the first and second calls together within the switch and drops at least one of the trunk connections. The switch may detect the voice path connection using an active approach in which a designated signal is generated on one of the first and second trunks and a determination is made as to whether the designated signal is detected on the other trunk. As another example, the switch may detect the voice path connection using a passive approach which involves monitoring the first and second trunks to determine whether they are connected in the external network.

Switch-based call processing with detection of voice path connection between multiple trunks in external network

The present invention provides an apparatus and system for accurately predicting and evaluating cellular system performance before an actual system is installed at a site. In accordance with an embodiment of the invention, only two persons (or under certain conditions, as few as one) are required to operate the portable measurement and antenna placement (MAP) tools of the invention, and evaluate system performance (e.g., voice quality) at varied locations of a site without the system being in place. A user can measure out the size of cells using a bar graph display that shows the range of acceptable signal levels for the system, and an audible warning tone that signals the user when the cell edge has been exceeded. In addition, other quality determinative system parameters (e.g., bit error rate (BER), etc.) can be evaluated simultaneously with voice quality and average received signal strength.
