you are correct; the long-held suspicion is that the mgcp between the pw and mg has proprietary extensions; using wireshark to sniff the protocol would be the first step; would need cold start, warm start, and normal operations captures; normal ops would contain lot's of normal and abnormal call scenarios; what's been missing for a long time is someone with the pw that could provide captures of the protocol to the mg however, i'd be more concerned about the legal aspects of such a project; without effort one finds: http://chillingeffects.org/reverse/faq.cgi the motivation for using brand X MG is to make something big; testing something big and deploying something big makes test case count and complexity go up rapidly; developing big switches at lucent, nortel, cisco, siemens, alcatel, ericsson enjoyed huge resources for testing; the linux kernel has a huge testing base because the equipment to do it is cheap and easily connected to the Internet; a large test base for testing large brand X MG configurations would be difficult to assemble, organize, staff, and maintain On Thu, Mar 15, 2012 at 5:50 AM, Stefan Schmidt <sst at sil.at> wrote: > Hello list > > i have read about chan_ccs which sound like what i want to try. > we now have a Cisco PGW talking to a switch over m2ua (?!) and also some > cisco 5400 media gateways connected to the same switch. > > When i understand this setup right (sorry i am not from the classic > telephone world ;) then chan_ccs would be able to do the same what this > cisco pgw does now.
