Summary:                    PRI Zap native Bridge fails upon connect of second
channel
Description: 
Hi Guys,

Full PRI installed in Canada with Sangoma A101DE and Asterisk 1.4.21.2,
LibPRI 1.4.10.

Placing a call into PRI and then transfering that call out to another
number results in a hangup. Problem is that the call rings out but the
moment the 2nd party pickups both legs of the call are disconnected given
Cause code 16. 

**********************************************************************
Incoming call is sent to this context to be bridge with another channel:
[zap_bridge]
exten => s,1,answer()
exten => s,n,Dial(ZAP/g0/4168889999)
**********************************************************************


*********************************************************************
CLI Output:
    -- Called g0/4168889999
    -- Zap/2-1 is proceeding passing it to Zap/1-1
    -- Zap/2-1 is ringing
    -- Zap/2-1 answered Zap/1-1
    -- Native bridging Zap/1-1 and Zap/2-1
    -- Channel 0/1, span 1 got hangup request, cause 16
    -- Hungup 'Zap/2-1'
  == Spawn extension (zap_bridge, s, 2) exited non-zero on 'Zap/1-1'
    -- Hungup 'Zap/1-1'
*************************************************************************

Here is PRI debug:
Starting just before Channel two is connected until both channels are
disconnected (maybe FACILITY 98 is of interest?!):

Any input and thought is appreciated on this. This is really annoying me
as there are no pointers as to why LibPRI is asking to disconnect once the
channel is connected.

Thanks,
Bruce
