VOIP provider: XO Communications
Issues: Inbound/outbound garble/jitter.
We’ve been struggling with our VOIP provider over QoS/CoS implementation. We do not have access to their router, and they will not give it due to security reasons, etc. They claim that QoS/CoS is properly configured, but we are having consistent call quality issues (garble/jitter) when a user initiates a download (for example). We never have more than (8) simultaneous calls going, and we are nowhere near using our bandwidth limit. Our provider claims saturation is causing this issue, but then again whats the point of QoS/CoS when voice is supposed to have priority over data?
We’ve been going back and forth with all levels of support. They keep saying that their configuration is on point, and that there is no issues with their circuit, or their hardware. Any advice or recommendations would be greatly appreciated. Thank you.
P.S. We can’t drop them yet due to contract.
