This idea has been batted around like a worn out cricket ball. It seems like a great idea but no one ever does it. Controlling AS5350 and other media gateways like it is usually done using MGCP. Open protocol - seems cool. Seems like something like Asterisk or ss7box could be the controller. In principle this is correct. The difficulty is that the MG makers have not published their protocol. The suspicion is that there are proprietary extensions to MGCP, and that reverse engineering might be a moving target, and not worth the effort. However, there's this: http://www.cisco.com/en/US/products/hw/univgate/ps501/prod_eol_notices_list.html The moving target problem has now be solved. The remaining problems are: 1) access to devices by those inclined to reverse engineer the protocol 2) 53xx is a dead product (supposedly these things are cheap and plentiful - but if there was a cheap MGC, maybe the supply would dry up? it's a limited market regardless) 3) reverse engineering may not be successful 4) reversing for Cisco, then Lucent, then another - is this the best way to spend our time? what about possible differences in model revisions? 5) full load testing is expensive - would you really want to deploy boatloads of E1 circuits using a system that's been undertested?
