No ringback for inbound callers

[allTel]

When we send inbound calls into a queue the caller receives no ringback or audio until we answer the phone. If we send inbound calls directly to an extension, the caller receives the ring audio just fine. Is there something about the queue setup that would suppress caller ringback?

More Info - We had configured the queue to overflow into a call group. We discovered that if we set the overflow to ring to an extension or forward to a outside number, then callers receive ringback audio as normal. Is this a know issue?

I had the same issue and after investigating found out that the problem was with my SIP provider. I alerted them to the problem and they solved it on their end.

I have the same issue, but i need to get a ringback because the length of time it takes the ivr to answer is about 20 seconds and it appears as the line is dead until the ivr answers. unless there is another work around for the lag before the ivr answers.
