A call that is placed off site must go through a gateway. This gateway could be a Cisco Media Gateway Control Protocol (MGCP), H.323, or Session Initiation Protocol (SIP) gateway. This course discusses how to troubleshoot these different types of gateways and provides an understanding of the most common issues that are associated with placing a call off site. During call processing, Cisco IOS voice gateways analyze digits and can perform digit manipulation. Understanding these functions and how a Cisco IOS voice gateway performs these tasks differently from Cisco Unified Communications Manager can help troubleshoot common Cisco IOS voice gateway issues. Cisco Unified Communications Manager provides the dial plan for most devices in a Cisco Unified Communications system. This dial plan is often the most complex troubleshooting area of placing off-site calls in your Cisco Unified Communications system. This lesson reviews dial plans, including globalized call routing, and addresses the most common issues that can occur with these dial plans. Other common voice issues that this course covers include troubleshooting missing or incorrect caller ID, ringback issues, one-way audio, dead air, dropped calls, and public switched telephone network (PSTN) setup failure.
