@Christian, no, I mean that while the user is on the phone they hear the far end party mixed with ringback tone in their ear. @Brad, we have not correlated it with hunt groups or even on incoming calls. We've only been able to capture it a couple of times and the times we have seen it, it has coincided with a slew of spanning tree activity on the LAN. Could be coincidence, but I am thinking there is an indirect correlation. Clearly the spanning tree is not SIP (and we are not seeing a 180 Ringing or other message that might confuse the phone) and is not inband ringback in RTP, but I am thinking it might be causing the phone to to wig out, though this is pure speculation. We also have the same concerns about file structure. On Fri, Jun 3, 2011 at 3:00 PM, Brad Anouar <Brad at broadcore.com> wrote:
We?ve had the same problem with FW version 3.3.1. We?ve noticed that it only happens when the call is terminated through a hunt group. There was some sort of a reINVITE that triggered a weird ring back tone in the middle of the call. Polycom support has acknowledged the issue and suggested to downgrade to 3.2.4, but as you probably know, the structure of the configuration files is different in the pre 3.3.x FW. The next FW version is scheduled to be released in July. We are still trying to come up with a work around.

Back in January there were a couple of posts related to "ghost ringing" on Polycom phones. At the time the workaround seemed to be to downgrade to v3.3.0 (we're on 3.3.1). Looking at the release notes on 3.3.1 it looks like the .0 release was pretty buggy and therefore we'd rather not downgrade to it. Polycom has not acknowledged (to us) that they even know about the problem. Does anyone know if any headway has been made in actually fixing the issue?
