Per the .pdf titled "Integrating Cisco CallManager and Cisco SRST to Use Cisco SRST as a Multicast MOH Resource" an FXO port can be used to attach a "live" MoH stream via a Cisco gateway.
One of the listed restrictions is:
"An FXO port can be used for a live feed if the port is supplied with an external third-party adapter to provide a battery feed."
Does anyone know of an adapter that will provide the battery feed? I have searched the Valcom, Bogen, Anixter and Greybar websites without any luck. Google has no idea what I'm looking for.
Thanks in advance.
