We have seen this on one of our polycom phones and it had something to do with the power adapter being fried. This was the only phone on an unprotected (non-UPS) outlet and we basically had to throw the adapter away and use a new one then the interferance went away and all was good.

On some calls there is a static-buzzing of sorts that occurs when users talk. It can be picked up on SIP-SIP calls and SIP-ZAPTEL (Channel BANK<<-T100P). It basically sounds really weird whenever someone talks, it sounds like a bee buzzing or something. Very hard to explain. Also, there will be echo on internal calls. We were not having any call quality issues with internal calls until recently. Upon inspection of the network, there isn't a virus or anything bogging down traffic. Additionally, the network is switched 100Mbps with a Gig port to our Asterisk Server. The Gig Ethernet card in the server is connected to the switch at 1000mbps. Any one know what other areas I can pursue? Thanks, - Brent _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
