asterisk users - Oct 2012 - a=recvonly

I am setting up with meetme a conf with X number of asterisk boxes and
"other" devices and phones. I am using the l parameter for all devices
being listen only
but I'm not sure thats happening as I am getting some feedback (some 
devices are close to each other like 5 feet).

How do I ensure that a=recvonly is being set or sent when bringing a 
device into the meetme?

Can I added that to SIPADDHEADER or something?

THere is only "one" device talking and all others should just be
listening.
I am using 1.4.43

Thanks,

Jerry

I've checked the code in Meetme and confirmed that feature should be 
working as expected. I would suggest you do some additional testing to 
confirm it isn't.

Asterisk doesn't allow you to manipulate the SDP as such so I'm afraid 
there is no way for you to change that value. Internally within 
applications they just discard the media received under such circumstances.
