level3_bx4-montrealak.net consistently dropping 50% of the packets

| Since you dont see packet loss on the subsequent hops, this is likely
just ICMP rate limiting on the control plane. MTR
| sends quite a bit of ICMP so this is very common when using MTR.

Not a "possible" reason for the degradation of voip from us to our service
provider?
Is there a more accurate test that will render more explanation?

Thanks for the prompt Chris.
