Go ahead. I am not sure how good it is. if you find problems , please let me 
know.

I am sure there must be problems there. But since I am also new, so I can't 
spot them all. that is why I posted it.  it will be nice that there are 
people spot the problem
and tell me. I can continue to improve it. when it is good enough, maybe 
this can be put in opensips repository
for everybody to share.

Thanks Jimmy,

I have been looking for some sample script for ages at every possible
place. So, far no luck but its really nice of you to post your script
here. I always wondered with open source software what is the deal of
posting your functional script (hiding your confidential info) but
never had an answer. Finally I see a brave person posting script...

Would you mind if i try your script and see if it works for me???


Thanks,
