Radio integration into Asterisk

Hi everyone!

Can Asterisk cooperate with Cisco Land Mobile Radio Over IP (LMR over IP)?

Generally, we need to assign a multicast group address to IP phones, so they can call into LMR multicast group. If i’m not mistaking, Call Manager Express can’t support this function.

Maybe Asterisk has a ready mechanism for my situation?

Is this a receive-only requirement? Like where a phone can dial an Asterisk extension and then listen to the LMR traffic? Or does it need to be be bidirectional audio with PTT control packets and the like? There’s nothing directly in Asterisk to join multicast groups, but I dont think it would be difficult to write. There is a Multicast RTP transmitter app that has been used for paging, though.
