I was wondering what could be pros and cons of ztdummy vs proper timer device (i.e. X100P). I am going to set up an asterisk server in europe (to do trunking, to save bandwith) and I was wondering if it'll be OK to get it going with ztdummy. Furthermore, I have only a 1024/256kbps PPPOE DSL link and I need to squeeze 12 channels through, I was wondering which codec would be suitable
