Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

简介

T1媒体网关(TIMG)和PBX IP媒体网关(PIMG)设备用于允许PBX将Unity Connection用作其语音邮件系统。从TIMG/PIMG到Unity Connection的通信通过会话发起协议(SIP)。从PBX到Unity Connection的通信通过时分复用(TDM)。

本文档介绍此类集成可能遇到的问题。

问题

Unity Connection配置为与TIMG配合使用，以便与PBX集成。当您呼叫PBX和无应答铃声或全部呼叫转移到语音邮件时，呼叫将转到开场问候语，而不是语音邮件问候语。

跟踪显示：

注意：已重新组织跟踪的某些部分，以便更容易查看。

TIMG组成邀请，因为它已收到实际呼叫。但是，此时，TIMG尚未收到来自PBX的任何呼叫信息。

注意：跟踪的剩余部分已被截断。

这里的主要问题是，来自PBX的呼叫信息在收到触发要发送到Unity Connection的邀请的物理呼叫后大约四秒钟到达。因此，由于没有转移，呼叫转到“开场白”：包含在Unity Connection的初始邀请中，用于告知Unity Connection哪个邮箱用于路由呼叫。

解决方案

要解决此问题，请导航至Configuration > TDM > General，找到Maximum Call Party Delay(ms)，然后将其更改为5,000毫秒等值。这会在初始邀请组成到Unity Connection之前增加5秒的延迟，这允许从PBX接收所有呼叫信息的时间。
