Hey all,

Hoping someone could assist. I have a buddy that inherited a idcs16 system when he leased a building and it was working fine for years but suddenly developed an issue.

When getting inbound calls it rings once then drops the call. You are able to call outbound as normal seems to only be affecting inbound. Any suggestions on what could check that may be causing it?

Idcs16 has a "6TRK" card installed only has 1line fed into the system.
Handsets are idcs 18d

Much appreciated

Used to see this sometimes as a ring trip. Could be an alarm but they are usually programmed to answer after more rings than that.A fax you should hear the cng tone if it answers.

Easy as mentioned , disconnect the line from the system and test.Problem still there?Then it's your line.

Problem goes away try a different line port.
