Ringing Noise on intercom call

[jjdad]

I have a Vodavi XTS system with Infinite DVX+ phones.

Three extensions have noise problems on answering.

When calling any of these three extensions on intercom, when they answer, you get a "fast busy" type ringing tone on the caller end. It rings about 3-4 times then goes away. Everyone has to wait until the "ringing" noise goes away before they can have a conversation.

Thanks!

It sounds like a cable problem to me. Hook a jack right at the ksu with jumper removed to affected extension. Plug same phone into jack, and test.

I did some testing and it appears the problem lies within the telephone itself. If it is on speaker phone, the noise exists. Plus the noise stays with the phone, even if you move it to another extension. Looks like this system has a couple bad phones.
