Hi all!

I'm creating a QoS in my network to priorize some traffic and it's working fine, but I don't know very well how I must to do with the VoIP priorization.

I've 40 ATAs in my network and these ATAs mark the packet with the value 0xB8 (184 in decimal). The manual of the ATA says that this is the defaul TOS mark value (0xB8) for VoIP in a network.

I don't know how can I use these marking in the mikrotik (version 4.13) because the DSCP parameter just accepts values between 1 and 64. How can I do it? What's the right form to use this markint in my mikrotik router?

PS: The wireless network is composed of Motorola Canopy radios and these equipments are working fine with the 0xb8 marking to priorize the VoIP traffic.

Thanks in advance

DSCP uses the higher 6 bits of the 8 bit (1 byte) TOS field in the IP header. Some implementations express DSCP based on just those 6 bits, which gives you values between 0 and 63. Other implementations express it based on the entire TOS byte, which gives you values between 0 and 255.

To convert between the two multiply/divide by 4. 184/4 = 46.

Thank you very much fewi!!!

Would you mind sharing the QOS configuration that you're using? I'm looking to do the same thing and I want to make sure I'm doing it correctly.
