Excuse my ignorance on the subject, but we have recently implemented a complete Cisco IP telephony solution, using Call Manager across dozens of sites. At our smaller offices, with maybe a 5-10 people, we have installed VoIP phones, connected via Cisco 877 router, and then over a 2MB ADSL Private Access Broadband service. Data is also going over these lines, and the calls are breaking up. QOS isn't possible over ADSL - but can the router be configured to implement some kind of QOS? Would anyone ever recommend attempting to do this? We feel our supplier has led us up a path to a solution that will never work.
