Assuming that you're using 1.2 or CVS head and default settings, yes.

The jitterbuffer(s) would be totally disabled on asterisk1 during the 
bridge, and the IAX2 JB on asterisk2 would see and compensate for all 
jitter introduced on packets flowing to the right, and the SIP ATA, in 
theory, would see all jitter introducted on packets flowing left; 
assuming it too, has a JB, it could compensate.
