Summary:                    iax2 hangs with jitterbuffer or timestamps - after
hang it does not accept calls
Description: 
i have following setup :

nokia_sip_client A-----sip-----B  1.asterisk B------iax2--------C
2.asterisk

ip-addr A,B is public 
ip-addr C is private

1.asterisk (Asterisk 1.4.21 or 080626_asterisk 1.6beta) is only there to
accept calls to forward them to 2.asterisk (Asterisk
1.4.21-BRIstuffed-0.4.0-RC3a) via iax2

1.asterisk has ztdummy(rtc) and 2.asterisk has zaphfc as timing
(ztdummy(rtc) is also loaded )

both asterisk use 1000hz kernel timing 

here the problem:
- having on both asterisk turned on jitterbuffer (jb) and timestamps (ts)
or on both asterisk either only jb or ts 
- sip_client calls voicebox at 1.asterisk - 2.asterisk forwards call via
iax2 to 1.asterisk 
- call gets going - with dtmf and so on - i stress test a bit (push often
dtmf) to reproduce error
- after a while - nothing goes and the call gets closed via 1.asterisk
eventually 

problem solving:
- turn off jb AND ts
- on 1.asterisk works fine - i can reload chan_iax2
- on 2.asterisk reload chan_iax2 says - Soft unload failed, 'chan_iax2.so'
has use count 1 - only "killall -9 2.asterisk" helps !
