It'll always be considered answered.

I have a simple dialplan with asterisk 18.14.0

exten => 141,1,Answer

exten => 141,n,Playback(beep)
exten => 141,n,Dial(MulticastRTP/basic/239.168.4.90:30410//t(15)
)
exten => 141,n,Hangup

Most times this works just fine ... Once in a while the person hears
the beep - but nothing connects on the multicast.

What might this be? How can I tell what is happening and why it does
not connect?

is it valid to put :
exten => 141,n,Dial(MulticastRTP/basic/239.168.4.90:30410//t(15)
)
exten => 141,n,Dial(MulticastRTP/basic/239.168.4.90:30410//t(15)
)

So if the first one doesnt connect perhaps the second one will ???
Thanks


Multicast doesn't connect. There is no session. RTP is thrown out onto 
the network using multicast, and then devices pick it up. Asterisk has 
no idea what (if anything) is receiving it. You'd want to do a packet 
capture to see what is being multicast.




Does this mean things like DIALSTATUS won't work as expected?

Multicast doesn't connect. There is no session. RTP is thrown out onto the
network using multicast, and then devices pick it up. Asterisk has no idea
what (if anything) is receiving it. You'd want to do a packet capture to
see what is being multicast.
