asterisk users - Dec 2009 - Force Jitter Buffer for SIP to SIP calls

We have a customer on a wireless connection that has very bad jitter. They
can hear people fine, but people have a very hard time hearing them. They
are connected via a SPA-2102.

It is a SIP client going to a SIP trunk.

Something like this in sip.conf [general] would be in effect for all SIP
clients:
jbenable = yes
jbmaxsize = 150
jbresyncthreshold = 1000
jbimpl = fixed
jblog = yes
I only want to enable the jitter buffer for the end points having the
trouble.

Reading the docs, it seems that the jitter buffer is only used when the end
point is connected to an app like voicemail.

This is from voip-info.org -
http://www.voip-info.org/wiki/view/Asterisk+config+sip.conf
It is in the [general] section

#  Asterisk sip jbenable = yes|no : Enables the use of a jitterbuffer
on the receiving side of a SIP channel. (Added in Version 1.4)
# Asterisk sip jbforce = yes|no : Forces the use of a jitterbuffer on
the receive side of a SIP channel. Defaults to "no". (Added in Version
1.4)

It mentions the 'receiving side' which should be the incoming or
upload form the clients.
As I am sure you saw, it is not mentioned in the peers and clients section.
Perhaps setting jbforce to no and jbimpl to adaptive.

I am sure you read all that, anyone have any real world experience?

Aloha,
