Re: [Asterisk-java-users] Reading a variable after call ends

Sure, every time I remove the listener before adding new one.
In effect my system should manage many calls, about 1500/2500 at day.
On the other hand, using an Agiscript I have the problem that in my method
I should update the db but doing so I update the db either in agiscript and
then in the code of originateAsync and may be not simple manage locking of
record because can happen that modification can be concurrent.
Thanks
