    • In providing personal telephone calling capability as a service, for reliability purposes, it is necessary to have available several independent meet-me systems, to provide redundant capability in the event of a failure of any one of them. Each meet-me system has at least 1) one meet-me bridge and 2) its own telephone trunks directly connecting it to the telephone network over which it receives return calls. A problem with doing so is insuring that the return call is properly bridged to the caller's call when a) the telephone number for the return call is a predetermined translatable telephone number and b) the particular one of the meet-me systems to which the caller's call is connected is determined only upon receiving in the network the call placed by the caller. To overcome this problem, at least each time a caller's call is routed to different one of the meet-me systems, the network routing data base which translates the dialed translatable telephone number of the return telephone call into a network routing telephone number is updated so that it will direct a return call for the caller's call to the same meet-me system to which the caller's call was routed. Advantageously, a hot-spare standby is not needed for each meet-me system. Instead, one additional meet-me system provides the capability to back-up the failure of any single one of the other meet-me systems.
    • 为提供个人电话呼叫能力作为服务,出于可靠的目的,有必要提供几个独立的会议系统,以便在发生任何一个失败的情况下提供冗余能力。 每个会议系统至少有一个会议桥,2)自己的电话中继线直接连接到接收返回电话的电话网络。 这样做的一个问题是确保当a)用于返回呼叫的电话号码是预定的可翻译电话号码时,返回呼叫被适当地桥接到呼叫者的呼叫,以及b)呼叫者的 只有在网络中接收到呼叫者发出的呼叫才能确定呼叫连接。 为了克服这个问题,至少每当呼叫者的呼叫被路由到不同的会议系统时,将更改拨号的可转换电话号码的网络路由数据库转换成网络路由电话号码,从而被更新 它会将呼叫者的呼叫定向到与路由呼叫者的呼叫相同的会议系统。 有利地,每个会议系统不需要热备用待机。 相反,一个额外的会议系统提供了备份其他任何一个会议系统的故障的能力。

    • Calls to geographically limited toll-free telephone numbers, when originated from outside the predefined geographic region, are completed, but not at the called party's expense, by a) indicating to the caller that the telephone call, which otherwise will be blocked, will be completed on his behalf if the caller provides for payment of the cost of the call and b) completing the call if a signal is received from the caller indicating that the caller agrees to pay the cost of the call. Advantageously, the caller is not automatically charged for what he believed would be a free telephone call. The caller may pay for the call by charging it to any conventionally available account for charging telephone calls to which the caller is authorized to charge charges. If the account associated with the caller's telephone is selected by the caller for charging the call, a further test is made to determine if the ability to charge the cost of such geographically-limited toll-free calls to the account has been blocked. If the ability to charge the cost of such calls to the account has been blocked, the caller is offered the option of selecting a different method of payment for the call. Alternatively, the direct dial telephone number to which the 800-type telephone number translates may be announced to the caller, so that he may dial it directly himself on a subsequent call.
    • 来自预定义地理区域以外的地理限制的免费电话号码的呼叫是完成的,但不是被叫方的费用,通过以下方式:a)向呼叫者指示否则将被阻止的电话呼叫将是 如果呼叫者提供了呼叫费用的支付,并且b)如果从呼叫者接收到指示呼叫者同意支付呼叫费用的信号,则完成该呼叫。 有利地,呼叫者不会自动向他收取他认为是免费电话的费用。 呼叫者可以通过将呼叫支付给任何常规可用帐户来支付呼叫,用于对呼叫者被授权收取费用的电话呼叫进行计费。 如果由呼叫者选择与呼叫者的电话相关联的帐户对呼叫进行收费,则进一步测试以确定是否阻止向该帐户收取这种地理上限制的免费电话费用的能力。 如果向帐户收取此类呼叫的费用的能力已被阻止,则呼叫者可以选择为该呼叫选择不同的支付方式。 或者,800型电话号码转换到的直拨电话号码可以被通知给呼叫者,以便他可以在随后的呼叫中自己直接拨号。

    • A technique for monitoring the calls placed to the telephone number associated with the party under surveillance. When a call to the telephone number associated with party under surveillance is placed, the call is routed via an assigned meet-me bridge, and a third party is provided with the unique telephone number of the meet-me bridge via a pager. When the third party places a call to the assigned meet-me bridge, the incoming call to the party under surveillance and the call by the third party are bridged. Thereon, the third party is placed on mute and the third party may silently listen to the conversation between the caller and the called party. When a call (i.e., a page) to a telephone number associated with a pager of the party under surveillance is received, a third party is alerted. Also, in response to the page, when the party under surveillance uses a specific calling card to place a return call, the return call is routed via a meet-me bridge having a unique number, and the third party is provided with this unique number. When the third party places a call to this unique number, that call is routed to the assigned meet-me bridge, and the return call and the call by the third party are bridged. Thereon, the third party is placed on mute and the third party may listen to the return call conversation.
    • 用于监视与被监视的一方相关联的电话号码的呼叫的技术。 当对与监视方相关联的电话号码的呼叫被放置时,通过分配的会议桥路由呼叫路由,并且通过寻呼机向第三方提供会议桥的唯一电话号码。 当第三方拨打指定的会议桥时,将对被监视方的来电和第三方的呼叫进行桥接。 此时,第三方静音,第三方可以静默地收听来电者和被叫方之间的对话。 当接收到与正在监视的一方的寻呼机相关联的电话号码的呼叫(即,页面)时,提醒第三方。 此外,响应于该页面,当被监视的一方使用特定的呼叫卡进行返回呼叫时,返回呼叫通过具有唯一号码的会议桥路由路由,并且向第三方提供该唯一的号码 。 当第三方发出呼叫到该唯一号码时,该呼叫被路由到指定的会议桥,并且返回呼叫和第三方的呼叫被桥接。 此时,第三方静音,第三方可以收听回叫通话。
