Re: [SR-Users] Time elapsed since previous message.

Hello Alex, Again thanks. I'm using that calculation to, when receiving a 180/3, if it comes in too quickly (i.e. 100ms) i cancel that call, and send a 480 the the A leg. I haven't found way of doing this, is this possible at all? I trired setting a very low t_set_fr(10,10) (0 means set the default), but that's not working... Is there a way of doing this? Thanks!
