Abstract

A switching system adjunct (120) monitors a call between a calling and a called party and reestablishes the call when one of the parties has been or is being dropped. The reestablishment may be effected to a same or a different phone number of the dropped party, and may be effected via the same or a different medium (e.g., wired or wireless). The call record of the original call is merged into the call record of the reestablished call, thus preserving the context of entities involved in the call that exists at the time that the party is dropped.
