Customer is complaining of a static sound or grinding sound when answering an incoming call. They said it lasts for just a few seconds, and the caller does not hear it. They say it does it on 80-90% of incoming calls. They just recently switched providers. They were using Atlantic Broadband with a modem that provides copper pairs to the SBX. The new provider has given them a similar converter. I'm not sure of the provider other than it's a local guy reselling - probably something like Nextiva with some kind of SIP gateway device that gives copper pairs to the SBX. The reseller / provider tested it and said it doesn't make the sound using a butt sett.

I see two threads without resolution that look similar. Wasn't sure if would be good etiquette to resurrect such old threads.
