Hi Bogdan, I was able to implement the channel limiting on one DID by using a variable instead of AVP and replacing all instances of $tU to $rU. Now, I want to limit the channels to a set of DIDs and I'm thinking of implementing a "while loop" and "counter" in order to achieve it. Is this an efficient way of doing the limiting on a set of DIDs? One problem I can think with the "while loop" and "counter" will be how to deduct those calls that were already hung up by the caller. Again, inputs will be greatly appreciated.
Thank you very much. --conpaj-- On Fri, Jan 8, 2010 at 4:53 PM, Bogdan-Andrei Iancu <[email protected]>wrote: > Hi > > It is hard to review scripts to see where the problem is, but I will > help you with some hints on troubleshooting. > > First of all you need to be sure you put in the profiles the calls you > wants - put some xlog() around the place where you add the call in the > profile (in the script).
