I have an IP Office that had no issues prior to the service provider switching to incoming fiber. We have Windstream, and they have a router that puts out the analog lines and data. This router was running on copper, and they replaced it with another router that is now being working on fiber into the building.
Since the cut over, you hear a loud static on the handset when you answer a call on the first ring of the phone. This did not happen before. The noise is NOT heard by the outside caller. The noise is NOT heard on the line with a test set. The noise is NOT the caller ID. I can hear that tone with my buttset normally after the first ring.
This is what is sounds like:
Here is a time line of the call:
Place a call on my cell phone.
First ring comes on the line, Call Status say "Pre-alerting"
Caller ID signal comes in.
Second ring comes in on the line, and the huntgroup rings for the first time.
Answer the call, and hear up to one second of loud noise, on the system phone only.
Call works normally.
If you wait for the first system ring to finish before you answer, you do not hear the noise.
I found this thread thread940-1648989 from 2011 explaining the exact same problem. In this thread, there is talk of a work around ( ) using an announcement. I have tried this, and it does not work for me. Call status shows the announcement being played, but when you answer quickly, you still hear the noise. I have also tried routing the incoming call to a user and forwarding to the huntgroup, sending it to another huntrgroup with no users, or a dummy user, with an overflow delay of a couple of seconds. Essentially, i've tried to build in some sort of delay, or way for the system to answer the call first, but every time when it rings the main huntgroup, you hear the noise.
I'm hoping someone else has encountered this problem since 2011 and may have a better solution. Before we had this issue the incoming lines were not POTS lines, they were still coming out of the CO's router. The only change is, there router is now being served by fiber not copper. This leads me to change it may be a configuration in their router. I've been working with Windstream, and we've played with line, CID, voltage, and compression settings, and have heard no change. We don't know what else to try.
