Understanding VOIP #3

Hi, thanks a lot for the findings.

I have the Nokia G-240W-A with Maroc Telecom in Morocco.

I would like to bypass their restrictions to use the VOIP account with my Asterisk setup in my LAN.

It seems the VOIP is on a separate VLAN from the pppoe connection. I know the main connection is on VLAN 881 because I am able to put the ONT in bridge mode and use the internet connection from a Mikrotik router and connecting to the pppoe server from there. I have the credentials.

But with the default configuration, I can't seem to find the VLAN of the VOIP connection. Also, it seems that there is a process listening on port 5060 on that VLAN. I can only ping the VOIP server by specifying that interface on that VLAN also.

Sorry I am just a software engineer, not a network specialist...

I found out the following interfaces:

gpon0
  gpon0.ani
    voip0
      pon_v90_0_1
        - inet addr:10.X.X.X Mask:255.255.252.0
        - vlan? (90?)
    veip0
      pon_881_0_1
        - main ppoe internet connection
        - vlan 881
ping <voip-server> doesn't work
ping -I 10.X.X.X <voip-server> works

That's where I am right now.

My ultimate goal is to go back to bridge mode and use both pppoe and VOIP myself, completely bypassing the Nokia. I am able to do it with the pppoe connection, but not yet for the VOIP.

Thanks a lot

Turns out that in bridge mode, the VOIP on the modem still works, and I still can use a second router for the Internet.

Will keep it that way... thanks!
