Ok, I will try this.

BTW I also checked the current and this one did not drop in.

regards

Disconnect supervision is evidenced by a drop in loop current voltage on the CO line when the other party hangs up the phone on their end.

An easy way to test this is to use a test set directly on the CO line with a volt meter set to DC volts and call your cell phone.
Hang up your cell phone but do not hang up the test set.
If disconnect supervision is enabled on the CO line you will see the loop current drop from 10v to 0v and then back to 10v until you hang up the test phone at which point the current will go to 48v.

Try it a few times and try it on every CO line to make sure the telco didn't miss any.

If disconnect supervision is present on the CO lines then you need to make sure that your SVMi is set to accept it in the PORT block under SAMSUNG IN-SKIN


I've probably said too much already since this is technician level stuff which we aren't supposed to post on the open forums so I won't go into details on how to check the settings in the SVMi.

Mods - if I overstepped my bounds here please edit this post.

You are good to go Pete thanks for asking. :thumb:

I checked this, but I don´t have the disconnect supervision enable in my CO lines.

I made the test, but the loop current did not drop, still in 10v didn´t change a bit, remain in 10v always.

Is ther another way to do this disconnect?, maybe with the tone cadence or something like that.

Thanks

You might set the SVMi to disconnect on silence, I've never tried it though.

Can you call the telco and add disconnect supervision? It should be working by default, but maybe you are in an area that it must be requested...
