Hello,
Suppose the following command, while MG supports the Pyaload types 0, 8,
18, 4:
(The unusual thing in this command is twice underspecified SDP)

MEGACO/1 [1.1.1.1]:2727
Transaction=111 {Context
=$ {Add=Physical1{Media{LocalControl{Mode=SendOnly}}},
Add =$ {Media {LocalControl {Mode = ReceiveOnly,ReservedValue=ON}, Local {
v=0
c=IN IP4 $
m=audio $ RTP/AVP $
v=0
c=IN IP4 $
m=audio $ RTP/AVP $
}}}}}

Which reply is correct?
Option #1:
MEGACO/1
[2.2.2.2]:2427
Reply = 222{Context = 4{Add = Physical1,Add = Ephemeral1{Media{Local{
v=0
c=IN IP4 1.2.3.4
m=audio 5678 RTP/AVP 0
v=0
c=IN IP4 1.2.3.4
m=audio 5678 RTP/AVP 8
}}}}}

Option #2:
MEGACO/1
[2.2.2.2]:2427

m=audio 5678 RTP/AVP 0 8 18 4
}}}}}

Option #3:

Reply = 222{Context = 4{Add = Physical1,Add = Ephemeral1{Media{Local{

m=audio 5678 RTP/AVP 0
v=0
c=IN IP4 1.2.3.4
m=audio 5678 RTP/AVP 8
