[Users] limiting number of calls

Hi, how can the dialog module help prevent the issue of missing BYEs?? Is dialog module capable of monitoring the sessions going on in openser. I also wanted to ask that if i try limiting the no. of calls that per user can receicve how do i match the invite with the byes. for eg: I may allow some users to have 5 incoming calls and other 2 and so on. So, I'll have to store that value in the DB table somewhere, and when a user receives a call, this column will be checked and the value should be decremented when he receives the invite message. But how do i again increment the value, when the user receives bye. I mean how do i write the logic to match the invite and byes so as to increment and decrement the simultaneous calls value. please help me regarding this.... thanks in advance. jayesh. --------------------------------- Yahoo!
