[Asterisk-Users] QoS in asterisk

[Rich Adamson]

Doesn't make any difference 'how' one might ping a remote site,
ping will never qualify the Quality of the channel between two points.
It will only suggest its up/down and possibly the delay at that
specific point in time. Has nothing to do with whether packets were
dropped or delayed some milliseconds before or after the ping, and
the ping pkt would never be subjected to any positive QoS parameters 
implemented in the point-to-point network infrastructure. A large
number of ISP's block icmp pkts anyway (for other reasons), so its
not a reasonable way to determine anything.
