Just wanted to check I've explored all of the options with our setup.

We recently ported our VDSL Vodafone plan to Fibre 100 with voice. With the new plan we decided to improve the network hardware and invested in an Edgerouter lite, a UniFi AP AC-Pro and a couple of TP-Link managed switches.

Thanks to the wonderful tutorials on this forum, the Edgerouter setup to connect to the OTN was easy to accomplish and it's ticking over nicely. The UniFi AP is fabulous and gives us great coverage. So the Ultra hub would be kind of redundant right? Well there's the rub - we have a broadband package with voice, and when I connect it up behind the Edgerouter the phone service doesn't work.

From what we've been able to glean from the forums here is that the problem lies in ATA being part of the Ultra hub and the configuration (sip server etc) is not available for the end user to adjust. Were that the case I could offload the settings (I assume) into our Gigaset A580 IP which already gives us offshore outbound VOIP connectivity to the family in Europe.

I've tried packet sniffing the WAN and LAN interfaces on the SIP ports (5060/5061) but the only thing communicating using that protocol is the Gigaset to a sip server in Switzerland. Tried to configure eth2 on the Edgerouter with a VLAN (15) which I also set the Ultra hub WAN interface to. Tries connecting the ultra hub via both LAN and WAN ports but no dice.

Can the Edgerouter be configured to have the Vodafone voice ATA in the ultra hub work or are flogging a dead horse?

If we are then is the best choice to go with a VOIP provider that we can port our 'landline' number to e.g. 2talk and cancel the voice portion of the VF broadband plan (if that's at all possible)?

The simplest solution is of course to just suck it up and have the Ultra hub be the router but then that leaves us with a redundant Edgerouter.

I know we should have done the research but I honestly didn't think the VOIP part of the changeover was going to be the challenge.

Any help much appreciated

As mentioned you can have voip services with vodafone by plugging in their ultrahub or huawei hg659 behind your edgerouter and disabling vlan tagging.

Plug in a LAN port from your switch or eth into the (usually) blue WAN port on the Vodafone box and make sure you set it to be on a sepearate subnet than the one your main network is on as it doesnt do this automatically. Vlan detagging happens on your edgerouter so you dont need this on the VF box. You will need Admin login to do this.

Also just as FYI for vodafone TV you can get this to work with Edgerouter. You need to configure a IGMP proxy for vodafones servers and allow traffic from them through your firewalls explicitly.

I have a config back when i used VF TV but id need to find it when i get back from holiday. If you search using the aforementioned terms you can find out how to get the IP addresses you need to work with.

A year or so back, I put together a short step by step guide on how to set up a Vodafone HG659 behind a third party router and still have the VOIP work: https://www.geekzone.co.nz/forums.asp?forumid=40&topicid=198107&page_no=3#1595908

As SpartanVXL said above, it is basically just disabling VLAN tagging on the HG659 and connecting it to your LAN via its WAN.

I unfortunately don’t have an UltraHub, so haven’t tested whether the same approach works for it, but I would expect it to.

An update on this as the OP.

After we upgraded the speed to max accounts changed and the previous setup failed (SIP 402/Unauthorised)

The good news is, that after searching this forum the answer was again in VLAN-land and was fuelled mainly by this thread (https://www.geekzone.co.nz/forums.asp?forumid=66&topicid=250644).

I first connected the Ultra hub directly to the OTN to make sure that the phone could connect and negotiate a connection with the SIP server and it could.

Then I set the LAN address of the ultra hub to 192.168.3.1 and enabled the DCHP

Reconnected the Edgerouter lite to the OTN.

In the dashboard tab of the Edgemax admin interface I added a VLAN to eth2 to create eth2.10

Then made sure to include the VLAN on the port forwarding tab

Added a DCHP for the VLAN so the Ultra hub would be passed a VLAN tagged address to its WAN port

And added the VLAN to the DNS forwarding list

Connect the eth2 port on the Edgerouter to the WAN port on the Ultra hub and connect the Siemens VOIP unit to a LAN port and Phone 1 on the ultra hub.

And it works. All thanks to the great people on this forum getting me to connect the dots on tagged VLANs.
