Description:Here is my Dialplan. Asterisk crashes at the Dial application. Using the Page application did not change anything and putting an Answer() into the dialplan did not help either. Changing the IP did not help either.

exten => 55555,1,NOOP(RTP)
exten => 55555,n,Dial(MulticastRTP/basic/127.0.0.1:4444)
exten => 55555,n,hangup()

Hi,

I have the same problem that occurs only once in two.
Asterisk version: 1.8.1
By: Yohann (wybecom) 2011-01-07 01:37:39.000-0600

In chan_multicast_rtp.c line 129:
1) control is never set, so is the control_address.
control_address is needed to instanciate rtp session (this is the local_address)

control_address is null, that's why asterisk crash...

No problem with asterisk-1.8.2-rc1
