You may think you're using g.722, but you're not, they only support g.711

Interesting, as I specifically asked customer support and they gave a different answer but obviously I trust the one you linked more.

Interesting that 711 is still better than any mobile call I've ever made.

Try setting your VoIP adapter to g.722 only. All outbound calls will fail. I know as I tried when I migrated and only g 711 would connect.

Tried again, and indeed, “Display Name” HAD TO be empty
Once re-registered, it works fine

A bit late to the party, I was also moved to Digital Voice with Zen, and using a Synology RT2600ac. We only receive calls on the landline, and I thought I'd repurpose an old smartphone with no SIM and use an Android app.

I first tried MicroSIP on the PC to begin with, and I got it to work. Then, however, of the two Android Apps I tried—MizuDROID and Zoiper—both can register and make calls, but neither can receive calls, and the SIP settings are the same between the PC app and the Android Apps. The PC is on wired, phone on WiFi, but the same IP network, and no router setting that is different for the wired and wireless clients. Any thoughts?

Edit: I cracked it. For those willing to use an app instead of a terminal, the key point is setting the local signalling port to 5060, not just the SIP server port. I figured this one out after using WireShark to trace the calls through MicroSIP and Zoiper—which I also installed on the PC—and saw the requests coming in on that specific port. Zoiper Free version does not allow to specify the local signalling port, either Android or PC, but MizuDROID does. Chicken dinner!

I thought I would post my lessons learnt as I have just spent bank holiday Monday getting my digital voice to work, mostly I wish I had found this thread earlier. I actually ended up trying out both methods when using an alternative router. (I use a vigor 130 in bridge mode and openbsd (PF) in proxmox in HA mode for my firewall)

1) Connect your Fritzbox to your phone line as the router and just make sure digital voice works. (They appear to have pushed an update to the Frizbox with the voip info in it, search to earily and your find nothing)

2) Export the config from the Frizbox (I used the password "a") then put your old router/firewall setup back

3) So what are my VOIP settings?
Registrar: voip2.zen.co.uk
Proxy: voip2.zen.co.uk
Username: <Your phone number>
Password: See below

4) So whats my password? If you use the Fritzbox you don't need (and I don't mean as a router see later)
I checked my Zen page as suggested by other people in this thread and sadly the info was not there.

So to get it I used the FritzBox Decoder As suggested by tdw42 it compliled out of the box on my linux machine. With the exported config I decoded it with

./decoder decode_export a < ../FRITZ.Box_7530_164.07.50i_29.05.23_1444.export
and searched for passwd in the file there is a voip section.

5) Easy method, you don't to even to part 3 or 4! On your Fritzbox go to wizards -> Configuring the Internet Connection
Select existing connection over lan
when it has reconfigured plug in LAN1 to you existing network.

Logon to the Fritzbox again in Home Network select the network settings and select IP Client-LAN configure a manual ip address or setup your DHCP server to give it a know IP. Skip to 7

6) Other FXS device I had also bought a Grand Stream HA612 for my Digital Voice change over, not knowing how useful the Fritzbox might be. IT Truely horrible interface! Set it up with a static IP or give it a known one via DHCP. Use the details for 3 and 4, tell it is using NAT and tell it your external IP address.

7) Firewall, I could have setup a sip application gateway on my firewall but that seemed complicated. So instead I redirected traffic from voip2.zen.co.uk (212.23.7.235) port 5060 and voice.zen.co.uk (212.23.7.228) port 5060 to the IP address of my FXS gateway/Fritzbox. That way I will not be bothered by people trying to direct call me via voip, I only wanted to keep the phone number as my Dad wanted to keep calling me on it.

8) Outstanding Issues....

Frittzbox client mode - None
GA812 outgoing caller id does not work. Meh not making calls from that line anyway but still only 9/10

9) Bootnote
If I get FTTP I will get a new install (with no phone) as suggested, then port my VDSL to sipgate which will kill my broadband. I didn't know that and thanks for the great advice.

Just to add another option for anyone else checking this thread.

Once you have moved to Zen Digital Voice, they are (currently) quite happy to let you move your number to another provider without impacting your FTTC/FTTP supply/contract.

It's only shown in the "old" portal - My services > General > View Technical Details, then select your Digital Voice order item.

Whole point of Digital Voice is NOT to have voice tied to the broadband
So moving the DV to anybody else will NOT affect existing broadband (nothing will be cancelled)

From a technical standpoint that is correct. It depends on the terms of your contract, some providers make it difficult to unbundle packaged services.
