Mid-call hand-off between end user terminals

A system providing a mid-call transfer service from an end user terminal participating in a call in a telecommunications network to another end user terminal, the system comprising:

• connecting means for connecting a first call through a first switching facility of the telecommunications network such that a first party using a first end user terminal served by the first switching facility and a second party are participating in the first call;
• sensing means for sensing a call condition prearranged to trigger the mid-call transfer service with respect to the first end user terminal, where the call condition is sensed at the first switching facility and different from a feature code to invoke the mid-call transfer service;
• invoking means for automatically invoking the mid-call transfer service for the first end user terminal based on the sensed call condition;
• calling means for placing a second call from the first switching facility to a designated telephone number associated with a second end user terminal in response to invocation of the mid-call transfer service;
• and,
• bridging means for bridging the second party to the second call after the second call has been placed such that the second call proceeds as if the second party had called the designated telephone number associated with the second end user terminal.
