I would like to comment just on the download QUE tree section.. We make use of a Cloudcore so instead of the specifiying the LAN bridge as per your example for traffic originating from your WAN connection we have to select the Eth 1 (LAN Interface)

My question is the following... Wouldnt this limit all traffic speed from other interfaces (branch office WAN for example) to the Eth 1 LAN interface ??

For example im my case just for testing Ethernet 1 is where all the phones would most likely be connected.

Wouldnt specifying ethernet 1 limit all traffic from other interrfaces to ethernet 1 ????

Or would a better idea be to put all VOIP phones on a VLAN and specifiy the VOIP vlan as the exit interface in the Download Parent Section ? Thanks

I have several customers using OOMA Voip and OOMA doesn't manage the SiP the same way you describe in the video where I can specify the SiP Destination IP. From OOMA support, "Unlike most other phone providers, we securely tunnel all SIP communications to our ooma SIP Servers." I am not sure how to mark the connection without the SiP IP. BTW: I have about 6 customers using OOMA and they are all experiencing choppy outgoing call quality (heard from their connected customer but not heard by them.) I want to set up queues but am stuck at the mark connection step. Any Tips? Awesome video BTW. Learned a lot.

Hello, callers cannot hear me when they call in (I can hear them), and on another VoIP app, the calls are oftentimes dropping. I was told that SIP ALG needs to be disabled, however, I work from on a phone data plan that I tether to my laptop. Will the phone company be able to disable SIP ALG in this regard, or what other options may I look into? Thank you!

What was the program you said you used to test customers or potential customers networks with?

@22:38 you have command line at priority 8 which is supposed to be 1 for the parent...but I guess the parent priority is not used anyways.

1. one way traffic call dialed is ok if any one wants to call its gives the phone busy
2. one way audio also is one more problem

I use 2 isp, and use 2 Mikrotik with different segments,

one isp has a problem, for example ISP 1 down, I move the segment path 192.168.216.0/24 through
mikrotik 2, with this configuration there is one way call, can you tell me how to fix it ??
