i ordered some lines to test with at our hq before rolling out some new boxes to replace some avaya partners in the field … the local lec is embarq
anyway they delivered them a while back and i called to have them check the options on them and discovered that they did not have disconnect supervision, hangup on disconnect or whatever you want to call it - kewlstart as we know it
i happily placed my order to have it changed - they happily accepted the order , BUT … then they called me back and regretted to inform me that the switch servicing us was too old , out of date , or something and could not provide any disonnect supervision …
after some discussion with them they said the next best bet was ground start signalling - said ok and they provisioned it
THEN i learn after some time trying to configure it that this is not an option with the digium hardware, TDM04B i believe - the 4 port fxo card; heck i thought ground start only applied to analog circuits ?
anyway looking around i see that other FXO implementations for FXO do respect and use Ground Start for disconnect signalling … one example being cisco
i’ve looked over the following :
and still dont like the options
am i missing something ? is there any other hardware anyone would recommend that can utilize ground start with FXO ?
