[Asterisk-Users] SIP Jitter buffer. What version of Asterisk PLEASE?

[James Gardiner]

Hi,
I am keen to try out the SIP jitter buffer capability.  I hear this was 
available if HEAD.

I was wondering if a version of the latest STABLE with this additional 
feature was available some place.. Or is it simply best to use HEAD?

Would some one be kind enough to point me in the right direction,
Thanks,
James
