a network message heard when an attempt to route a call to a nodal or ISDN T1 on the terminating end fails due to no call set-up signal from the PBX being received by the far-end Tandem or edge switch "Your call did not go through, 9142T". Optus has an intercept message which is heard by Optus customers when the network is congested or when a technical fault prevents customers from making phone calls: "Unfortunately due to temporary service difficulties, we are unable to connect your call at this time. Please try again later". After the message is played, the call will disconnect. Phone left off-hook If a phone receiver is left off-hook, sometimes an intercept message is used to inform callers to hang up their phone receivers. The most common message reads as follows: A formerly-used variation of this message was as follows: The message may be repeated, then followed by a loud, rasping off-hook tone intended to remain audible even if the handset is on the desktop instead of at the subscriber's ear. This tone is louder than the standard busy/fast busy signal. In Australia In Australia, a user is often given the following message signifying that a call could not be connected. It is voiced by Anna Hruby, who is known as "The Telstra Lady" for her distinctive and memorable voice. This only applies to the Telstra Network; however, Optus and other networks have similar messages, each voiced by a different individual. Telstra: "Your call could not be connected; please check the number and try again." and "The number you have called is not connected, please check the number before calling again." Optus: "Optus wishes to advise that the number you have dialed was incomplete or incorrect. Please check the number and dial again." Vodafone AU: "You've mis-dialled a number; your call will not be connected. If you want emergency services, please dial Triple Zero." The message is usually then followed by a series of letters and numbers signifying the local access switch associated with the caller's exchange or the receiving party's exchange. Variations and enhancements In almost any case, a telephone switch may be programmed to return a slow or fast busy signal instead of an intercept message. Intercept messages also often end with a coded identifier signifying which switch the message is being played by; this can be useful for diagnosing network problems. References External
