Summary:                    Dial MulticastRTP channel with A option can't play
the file
Description: 
Hi everybody,

I am trying to play a message to a multicast channel:

 Dial (MulticastRTP/basic/239.255.1.1:5004,,A(demo-moreinfo))

I can talk to the channel but the message is never played:

 Using SIP RTP CoS mark 5
    -- Executing [1001 at default:1] Dial("SIP/10.147.248.29-00000003",

    -- Called basic/239.255.1.1:5004
    -- MulticastRTP/0x2306b728 answered SIP/10.147.248.29-00000003

Yes there is traffic in the capture but it's not the traffic caused by the
A option. It's the traffic generated by the caller.

So, when dial a multicast destination with A option or not, the caller is
always heard from the listening phone. It's not a configuration issue on
the listening side. The fact is that you can't stream a file to the
multicast channel.

Kind regards,
Yohann
