Hi Team,

I've a small doubt. I have a working call where A party is talking to B party. 
B party putts the call on hold, however I see "Session Attribute" with a value 
"SendOnly". Mostly I've seen it coming in Media Attribute.

"Session Attribute (a): sendonly" Instead of "Media Attribute (a): SendOnly".

What's the difference?

I've read some phone (PolyCom) while its set to a different settings, do this.
For e.g
voIpProt.SIP.useRFC2543hold     0 or 1  0

When the phone is set to 0,  use SDP media direction parameters (such as 
a=sendonly) per RFC 3264
Otherwise use the obsolete c=0.0.0.0 RFC2543 technique

Could someone throw some light? Just trying to figure out the difference?

Cheers,

Sylvester
