Call-associated data transfer among multiple telecommunication switches

摘要

A telecommunication system includes a first type of telecommunication switch and a first server coupled to the telecommunication switch. The system further includes a second type of telecommunication switch and a second server coupled to the second type of telecommunication switch. A data network link coupled between the first server and the second server allows call-associated data to be transferred between servers when a telephone call is transferred from the first type of telecommunication switch to second type of telecommunication switch.
