This is a question around QoS tagging my VoIP, using World Exchange over Chorus UFB, ISP is Vodafone so it could really sit in any number of forums :-).
I have a Mikrotik into the ONT on VLAN 10 DHCP, all working perfectly.
I created a mangle rule to identify outbound VoIP packets and tag them with 802.1p = 5.
(I used 5 as that is what is specified in https://www.chorus.co.nz/file/48702/Bitstream_2_Acelerate_Service_Description-June-2014-Final.pdf)
I ran a packet capture during a VoIP call and confirmed my outgoing RTP packets are being tagged correctly - hopefully this means I am going through the 2.5 Mbps high priority CIR.
I then took a look at the inbound packets from World Exchange and noticed they do not have any priority or DSCP tag. I'm wondering if I should be seeing a priority tag on these inbound packets through to me, or if they are lost somewhere through the network? Maybe World Exchange does not tag packets, or they are being stripped somewhere in the middle or maybe even at the ONT?
An outbound RTP packet:
802.1Q Virtual LAN, PRI: 5, CFI: 0, ID: 10
101. .... .... .... = Priority: Video, < 100ms latency and jitter (5)
1011 10.. = Differentiated Services Codepoint: Expedited Forwarding (0x2e)
An inbound RTP packet from World Exchange:
802.1Q Virtual LAN, PRI: 0, CFI: 0, ID: 10
000. .... .... .... = Priority: Best Effort (default) (0)
0000 00.. = Differentiated Services Codepoint: Default (0x00)
Hoping some VoIP, QoS, UFB gurus can shed some light on this for me.
