Gotta gig next week installing an xBlue X16 for a customer that is moving there office. Their new phone service will be via Comcast over the cable modem, then to a converter with 4 analog trunks coming out to the pbx. Has anyone had issues with this type of setup on an xBlue? We've seen some weird stuff using this same setup on an Avaya IP Office with poor audio quality. Just seeing if I needed a heads up on anything. Thanks.
