Hello, I asked this question on my local linux user group mailing list, and got the recommendation to ask here. Anyway, at the moment I am running Asterisk on an IP04 embedded system. http://www.rowetel.com/ucasterisk/ip04.html It works well most of the time, however there are some bugs that do, under circumstances lead to less then desirable behaviour (such as on some occasions which I don't fully understand sometimes the remote system fails to generate any audio packets when there is no audio - almost like silence suppression was supported by the remote system - and asterisk fails to generate any audio packets in return; on another slower computer running the same SIP software and on the same network everything works fine; as far as I can tell the software - twinkle - doesn't even support silence suppression). I suspect at least some - if not all - of the issues I have encountered may be resolved with Freeswitch, however I don't really want to replace my small, energy efficient, embedded system, with a large, power hungry computer system. Overkill. An added complication is I need at least 1 analogue port to connect to the Australian based telephone line (2 ports exchange ports and 1 extension port would be ideal but not essiential). Unfortunately, I have been told that the IP04 hardware isn't compatable with the requirements of Freeswitch. Such as not having a MMU. So there doesn't appear to be much effort porting Freeswitch to IP04 as a result. I do have a spare TDM400p card, although as it is full height, suspect this isn't going to help. Are there any other good alternatives? Thanks. -- Brian May <brian@microcomaustralia.com.au>
