How to disconnect a call that is not hung up

[cameron.beattie]

We have attached an intercom system to a Cisco SPA112. The intercom system does not hang up the call. When the far end hangs up the call a disconnect tone is played for a long time. Is it possible to control how long that is played for? Is it possible to force the SPA112 to hang up the call quickly?

Did you solve the problem?

Note the original question is wrong. SPA112 is the server side of the analog line, the intercom is the client. As long as intercom is holding line seized, there is nothing the server side can do. It may play disconnect tone, it may revert do dial tone, it may remain silent, but it is unable to order the intercom to hangup unless intercom decide to do so.

So learn the ways your intercom (note that your intercom may not be the same as intercom of cameron.beattie) use to decide the line should be unseized.

We can search if it's requirements may be fulfilled by SPA112 then.

There is no advice until we know the requirements of the intercom in question.

Also note the question is off-topic here. SPA112 is not SPA IP Phone but ATA kind of device.
