hi,
this looks ok for me... as long as you dont forget to remove the listener.
I also would check the impact to the whole system / performance / memory
usage depending on the amount of calls
your code has to handle... i could imagine that this is not healthy for
high traffic... if you have a high call volume you
maybe should go another way.... but try it out and give feedback,
yves
