How can I create an audio broadcast over the Cisco IP telephony network so that any user can start listening to the broadcast audio signal if they wish?

Question

Telephony

Good afternoon,
There is an IP-telephony network based on Cisco Unified Call Manager, if the source is an audio signal (for example, a conventional radio). The network has a 2901 router with an E&M analog expansion card. The alarm is disabled on the port and the number is configured, you can call and listen, but the analog line accepts only one subscriber. The question is how to get around this limitation, or how else can you organize the access of phone users to listening?

Answer 1

Enable the multipoint audio conference option, add a number with an audio stream there. Then everyone will be able to call the conference and listen.
If there is no option, I recommend deploying OpenMCU
