Hi All,
I have a weird problem I have been debugging for a while. I have been using my setup (OBi200 google voice with Cisco SPA514G SIP phone for years now. I believe the problem has begun to occur more recently but not sure. I have been on more long conference calls lately where I am muted. When on a conference call (Webex for example) and my phone is muted, conference members sometimes complain of bad feedback and echo after a while. Webex shows audio coming from my line even though my Cisco phone is muted (this is how I first keyed into it maybe being me). If I mute at the source via webex interface or conference line that allows you a *X command the problem goes away. I have also noticed that if I unmute my phone briefly the problem will go away for a while. Meaning I think it only happens when my phone is muted for some time. When on a call where I am active or don't have my phone muted the problem is never encountered. So it appears it only happens after I have been on mute at my phone for some time - maybe 10 minutes or more but not sure.
I don't believe any configuration changes have been made lately (I think I have code locked down - currently at 3.2.1 (Build: 5757EX)). The only change that I can figure out is that I did have a POE switch die on me and I replaced that. The new one is a BV-Tech. But not sure when this really started.
Thanks in advance for helping me with this.
