asterisk users - May 2005 - Setting the jitter buffer in AIX

Are these things possible?

1) Set the local Asterisk jitterbuffer size, but only for a particular 
connection.  I'd like to force Asterisk to use a particularly large 
buffer in certain cases.  Should I expect this to work?

[general]
jitterbuffer=no
register => username:password@parcelfarce.domain.net	;parcelfarce
register => username:password@iaxtel.com		;iaxtel

[parcelfarce]	;connection to parcelfarce
type=friend
auth=md5
secret=password
context=inbound-from-parcelfarce
host=parcelface.domain.net
qualify=yes
jitterbuffer=yes
maxjitterbuffer=600   

2) Set the remote jitterbuffer.  I want to tell the remote Asterisk 
that, during this call or part of a call, that a much larger jitter 
buffer is OK.  Basically I care more about quality of the delivered 
sounds, rather than latency.

3) Monitor the remote jitter buffer discards.  I want to know if my 
outgoing stream is breaking up.

Here I am building an information retrival service, so conversational 
latency is not an issue.  The remote Asterisk is at a PSTN company such 
as VoicePulse, TelAIX or LiveVOIP.

I don't think so -- I think maxjitterbuffer applies globally.

Nope.

The new jitterbuffer in CVS-HEAD provides this functionality, via IAX 
RR (receiver report) IEs, and you can monitor these via "iax2 show 
netstats" from the CLI or Manager.
