#### Step 1 - Copy the queue onto the router. ##
#### Step 2 - Identify the VOIP traffic. In this example, 3 phones have bee identified by their IP address. ##
#### Step 3 - Adjust the Parent Queue upload and download speed to max speed delivered to the router. ##
#### Step 4 - Adjust the VOIP queue and the "All Other Traffic" Queue so that their max upload and download is equal to or##
#### less than the Parent Queue. ##
#### Step 5 - Adjust the limit-at speed on the VOIP queue so that the speed is set to 250K X #_of_VOIP_Streams. In this ##
#### example, there was three lines, so limit-at was set to 750K. ##

Hi, i am starting learning mikrotik, thanks for this blog.
I have one question, this script means:
total bandwidth is 1 mbps for upload and 25mbps for download
reserve 1mbps for upload for 3 host and assign 2 mbps download for 3 host
the restant bandwind for the nework.
it is true?
thanks, regards from Colombia – South America
Hi Jhon,
The script is:
One line #1, defining the amount of bandwidth that is available as a whole (1M up/ 25M down):
add max-limit=1M/25M name=”Office Parent Queue” target=10.254.254.0/24
The queue in line #2 is subordinate to the “Office Parent Queue” and is guaranteeing 750K/750K to the phones, but allowing them to use as much as 1M/2M if its available.
add limit-at=750k/750k max-limit=1M/2M name=”VOIP Traffic” parent=”Office Parent Queue” target=10.254.254.231/32,10.254.254.232/32,10.254.254.233/32
The queue in line #3 is also subordinate to the “Office Parent Queue” and is equally dividing the bandwidth of 1M/25M to however many users request if from the target subnet.
add max-limit=1M/25M name=”All Other Traffic” parent=”Office Parent Queue” queue=pcq-upload-default/pcq-download-default target=10.254.254.0/24
The overall idea here, that the phones always have bandwidth if they request it, but its shared if the phones are not using it.
