[asterisk-ss7] testing chan_ss7 ws libss7

[Vazir]

Matthew,

Made a testbed as of

TESTPC < -- > PC_CHAN_SS7 < -- 4xe1 -- > PC_LIBSS7 

So PC_CHAN_SS7 is test1 in logs below
and PC_LIBSS7 is test2

Testpc generates huge load by placing call files to 
the /var/spool/asterisk/outgoing and connecting local 
extension which plays "hello world" va SIP to PC_CHAN_SS7 
which than places an SS7 call to PC_LIBSS7. TESTPC also 
records all of the placed calls by Monitor() for further  
manual (audial) analysis .

LIBSS7 initially working and there is both-way audio in all 
CIC. After a few minutes of the loaded operation it fails 
signalling (chan_ss7 PC shows that it looses connection) 
but even if I stop asterisk on PC_CHAN_SS7 - the libss7 
keeps thinking that there is connection. Restart or any 
manipulations on PC_CHAN_SS7 brings no result and to 
restore the link asterisk on PC_LIBSS7 must be restarted.
