Abstract: A pinging electronic device, a pingable electronic device and a network for the devices are disclosed. The ping electronic devices comprising a ping function and a transmitter wherein the ping function is adapted to generate and the transmitter is adapted to transmit over an ad hoc wireless network at least one associated ping control message to at least one pingable electronic device paired to the pinging electronic device for actuation of at least one indicator element of the at least one pingable electronic device.

Abstract: A method of placing a call from a handheld device to a receiving device using VoIP includes initiating the call, transmitting a plurality of voice data packets to the receiving device, determining whether the receiving device has detected one or more missing or delayed packets, and providing a poor voice service indicator if it is determined that the receiving device has detected one or more missing or delayed data packets. Also, a method of placing a call to a receiving device over a network system which allocates bandwidth includes sending a request to the network system for a bandwidth allocation for the telephone call, determining whether the request has been granted, providing a poor voice service indicator to the user of the handheld electronic device if it is determined that the request has not been granted, and transmitting a plurality of voice data packets to the receiving device.
