Total Access 9XX - Bookending: Extending analog trunks over SIP
NOTE: This feature requires A2.05.00 or newer firmware.
The sample configuration below is designed to be used as a basic voice configuration template for extending analog trunks (FXO to FXS) over a packet network on the TA 9XX series. Two TA 9XX series IPBGs will be required to complete this application, one at the main location (FXO) and one at a remote location (FXS).
It is assumed that the routing features of the IPBG have already been configured. For more information about configuring IP interfaces for AOS voice applications, see this guide:Configuring IP Interfaces for SIP in AOS IPBGs . Before pasting the config at the privileged (enable) prompt of the command line, make sure and replace the SIP server address with the appropriate IP address (or hostname) of the remote device. It is also important to note that the media-gateway command must be applied to any interface used to source SIP or RTP traffic. For more information about the media-gateway command, see this guide: . For information on how to access the command line and enable prompt, see Accessing the Command Line Interface in AOS
